EXPLORING THE APPLICABILITY OF PRODUCTION SHARING
AGREEMENTS TO OFFSHORE WIND PROJECTS
Chapter
1introduction
The purpose of this exploratory research is to examine whether hydrocarbon
PSA-like contract terms could be applied to OWE projects and is the first to attempt
such analysis. PSAs are used in the hydrocarbon industry in more than eighty
countries, most of which are considered developing or undeveloped nations (Wood
Mackenzie, 2022). The contract governs the terms of the lease of seabed for O&G
exploration, development, and production (Johnston, 1994). It outlines the rights,
duties, and obligations of the contracting parties. The lessor in the agreement, the
party who leases the seabed for the hydrocarbon project, is the resource owner,
which in most countries globally is the government (hereinafter known as the
Government). The lessee is typically the energy company or investor who will be
building and operating the projects (hereinafter known as the Contractor). PSAs are
widely used in the hydrocarbon industry (Kaiser & Pulispher, 2005a) and when
properly structured,
are considered a successful and attractive contract by which governments lease seabed
to industry (Luo & Yan, 2010; Pongsiri, 2004; Zhang, 2022).
OWE has in the past required government subsidisation to be economically
attractive, but this era is ending (Jansen et al, 2022). Countries, such as developing
nations, which could not afford to subsidise offshore wind, may wish to encourage a
national energy transition. This transition could be away from polluting hydrocarbons
towards renewable energy. It could be away from energy dependence, if no
11
hydrocarbon industry is present, towards independence through renewables which
may be sourced locally. There is no requirement for these countries to follow existing
12
offshore wind leasing models, conversely, there is an opportunity for them to shape
new contract terms for offshore wind. This research looks at capturing contractual best
practices from the O&G industry and testing their applicability to offshore wind, to
explore an alternative leasing mechanism for future projects.
Successful application of the contract terms to offshore wind projects depends
upon the project having a positive financial outcome for both parties to the
agreement. A positive financial outcome is defined as the generation of a positive net
present value (NPV) for both parties. Thus, the quantitative phase of this exploratory
mixed method research addressed five research questions (RQ) through stochastic
cash flow modelling in combination with multiple regression (“meta-modelling”) and
scenario analysis. The use of these methods in combination unifies the best of
industry practices and academic rigour. These RQs concern the economic viability of
the PSA- like terms, their impact on offshore wind project profitability, the optimal
set of contract terms, and the effect of project characteristics on profitability. RQs 1, 2
and 3 (below) take into account the perspective of both parties to the contract, which
is an advance on earlier research.
RQ1-1: Is the wind farm characterised by a positive NPV for the Contractor under the
PSA contract terms modelled?
RQ1-2: Does the wind farm provide a positive NPV to the Government under the PSA
contract terms modelled?
RQ2-1: What effect does each contract term have on Contractor NPV?
RQ2-2: What effect does each contract term have on Government
NPV?
13
RQ3-1: What effect do other inputs such as Discount Rate, Price, and Power
Generation have on Contractor NPV?
RQ3-2: What effect do other inputs such as Discount Rate, Price, and Power
Generation have on Government NPV?
RQ4: Can the optimal set of contract terms be discovered for a given wind farm?
RQ5: How do the NPVs fare under different power generation, price, and cost
conditions?
Adoption of the contract by governments as a leasing instrument for offshore
wind is also dependent on it having attractive features not present in existing
contracts.
The qualitative phase explored the reasons behind using PSAs for hydrocarbon
leasing and the benefits which could accrue if PSA-like contract terms were used for
OWE. This phase of the research employed interviews with O&G industry
professionals to address RQs 6 and 7:
RQ6: What are the advantages and disadvantages of using PSAs in hydrocarbon
leasing?
RQ7: What could be the advantages and disadvantages of using PSA-like contract
terms in leasing for OWE projects?
A successful outcome of this research involves finding that PSA-like terms can be
used for OWFs and that there will be benefits for both contracting parties. These
factors would entice a Government to offer and a Contractor to accept the terms. In
that case, this research would provide a new type of leasing arrangement for OWE that
may attract developing countries to add another renewable source to their energy
transition.

CHAPTER 2
REVIEW OF LITERATURE
Note on Grey Literature
Grey literature is defined as publicly available writings which are not controlled
by commercial publishing (Lawrence et al, 2015) i.e., have not gone through the
traditional peer review and publishing process of an academic journal. Its
incorporation into research can be positive, and is becoming increasingly important
(Adams et al, 2017). Pappas & Williams (2011) point to the delay between research
and peer-reviewed journal articles in their field of medicine and argue that grey
literature fills the time gap between cutting-edge research or innovation and
publication. Grey literature is produced by governments, academics, businesses, and
industry; it is protected by intellectual property rights; and whilst it is often of
sufficient quality to be preserved in libraries, it is not peer reviewed (Adams et al). In
the course of this study, the researcher has observed the progression of OWE to be so
rapid, that to rely solely on academic literature would mean missing the latest trends
and events. Thus, the following literature review contains references to articles,
reports, and web pages which have been published but not peer-reviewed.
Energy Transition
“Our addiction to fossil fuels is pushing humanity to the brink. We face a stark
choice: Either we stop it — or it stops us........We are digging our own graves." - U.N.
Secretary-General Antonio Guterres at the COP26 conference in Glasgow, UK in
November 2021 (Associated Press, 2021).
15
As world leaders acknowledged at the 26th Conference of Parties (COP26), the
existential threat to the planet from climate change must be stemmed. Energy derived
from hydrocarbons must be significantly reduced and replaced by energy originating
from renewables (Alolo et al, 2020). Indeed, a shift from hydrocarbons is key for
reaching already agreed-upon climate goals, as well as the more ambitious goals that
will be required to halt climate change (IRENA, 2019). Many countries are well-
endowed with renewable energy resources, including solar, geothermal, hydropower,
wind, and biofuels. In 2022, 40% of global installed power capacity came from
renewable sources, which was a 5% increase in renewable capacity over the prior year
(IRENA, 2023). More startlingly it represents a 48% increase over a decade before.
Encouragingly, according to Haegel & Kurtz (2023), whose data is used by the
National Renewable Energy Laboratory (NREL), 83% of new power generation
capacity added in 2022 came from renewables. Contrast that with 2018 when the
number was only 65%. This research aims to provide one small piece of the energy
transition jigsaw and demonstrate that the use of hydrocarbon PSA-like terms could
provide a leasing alternative for OWE to developing nation governments.
Renewable Energy’s Benefits
A drive towards renewable energy can mitigate two energy-related challenges for
a nation: dependency on fossil fuels, often imported from other countries, and climate
change (Lee, 2021). Some countries, such as Jordan, which imports 94% of its energy
needs, see an opportunity for improved energy security through developing domestic
renewable energy sources (Abu-Ramman et al, 2020 and IRENA, 2019). While this
will
16
not mitigate the need to import liquid hydrocarbon fuels for transport, it can still have
beneficial environmental and security of supply impacts on domestic power generation.
Similarly, Namibia imports its power from neighbouring South Africa, Zimbabwe,
and Mozambique; those contracts can fill 92% of Namibia’s peak demand. However,
the country has the potential off its own shores to fulfil its demand with OWE (Choti
& Xydis, 2022) and become power independent. The same two reasons cause
Bangladesh to have ambitions to tap into its own solar and wind (initially onshore,
subsequently offshore) assets rather than import increasing amounts of hydrocarbon
fuel (Alam, 2022).
Security of energy supply and climate change are two of the four reasons driving
Russia to pursue policies to support renewable energy (Kudelin, 2021) – the other
reasons being a decrease in negative health effects and the associated cost, and
replacement of declining hydrocarbon resources. Pakistan (Rabbani et al, 2022) sees
four reasons to switch to renewable energy: energy security, reduced use of fossil
fuels, economic benefits, and job creation. Nigeria (Idris et al, 2012) has five reasons
for a switch to onshore wind energy: security of supply, decreased reliance on
hydrocarbons, fewer negative effects on the environment, increased socio-economic
development, and improved quality of life.
Vietnam does not subscribe to the common belief that pursuing green policies
will stunt development, but rather that it will accelerate due to the adoption of
technology and improved energy efficiency (Zimmer et al, 2015). The country wants
to improve energy supply security, act as a role model, and attract foreign investment
and donors due to its responsible attitude towards climate change (Zimmer et al). The
authors find
17
Vietnam suffers some of the worst air pollution in the world, has a long coastline
making it vulnerable to rising sea levels, and the coal, oil, and gas that fuelled the
economic development since the 1990s are being depleted. A shift to renewable
energy makes sense.
Atteridge et al (2012) discuss the shift in policy in India, which had very low
greenhouse gas emissions per capita between the 1990s and 2012. The former two-
fold policy was centred around the country not being part of the climate change
problem, and that spending on a shift to renewable energy would compromise the
national goals of poverty reduction and economic growth. The authors find that by
2012 India had become concerned with energy supply security and decreasing imports
of fossil fuels, both of which could be achieved by a shift to renewable energy. They
state that the goals of energy security, economic growth, and poverty reduction can be
achieved in a way that has a side-benefit of mitigating climate change. Thus, India is
beginning to emulate wealthy countries in some policies.
Gopalakrishnan et al (2023) suggest that the “fragile states” – often developing
countries – can achieve wider access to power at a lower cost with renewable energy
than with fossil fuels. They can benefit locally from the transition and not just through
their contribution to the global drive to mitigate climate change.
Further, the expectation (Tavakolian et al, 2022) is that hydrocarbon exploitation
will become more expensive in the future as the easy-to-access, conventional
resources are exhausted. This will make renewable energy more competitive.
Additionally, new sources, such as oil sands, have a more deleterious effect on the
environment than sources already tapped, such as light, onshore oil deposits. It is
true that the shift in
18
recent decades from coal- to natural gas-fired power plants is better for the
environment. In the US alone, 121 coal-fired power plants were converted to natural
gas between 2011 and 2020 (Aramayo, 2020). However, this improvement may be lost
if future sources of natural gas are sufficiently difficult to access and transport that the
harm to the environment accelerates again.
The Problem of Intermittency
Naysayers often point to the intermittent nature of renewable energy sources as a
barrier to success, and indeed this is a major concern in comparison to stable baseload
technologies using hydrocarbons as fuel. However, Bhandari (2014) and IRENA
(2019), discuss the clustering of two or more renewable technologies, known as hybrid
renewable energy systems (HRES). Such systems improve the intermittent supply issue
inherent in naturally occurring power sources. These can be connected to the existing
grid so that power can be pulled from the grid if the renewables cannot meet peak
demand, eliminating the need for storage - (Bhandari). If the system is not connected, it
can include lithium battery storage, but the battery can be smaller and cheaper than in a
single source system, whose intermittency problem will be greater (Bhandari). Some
use diesel fuel to replace renewables when demand cannot be met (Bhandari). That
offers a transition away from hydrocarbons but does not entirely replace them.
However, the HRES/diesel combination does solve the unnecessary expense of
oversizing the system for peak demand (Bhandari). The author, in his 2014 literature
review, points to studies, some theoretical and some functioning in practice, designed
as follows: solar and wind with battery; solar and wind with grid connection; solar and
hydro with grid connection; solar and wind with diesel (seen in Palestine); solar, wind
and hydro with
19
battery; solar, wind, battery and diesel (seen in Malaysia); and wind-pumped hydro in
Ethiopia (the water, pumped to a height acts as the storage mechanism). These projects
are all small-scale, but solutions such as these are expected to be seen increasingly,
and since Bhandari’s 2014 paper, hydrogen has emerged as a new storage technology
(IRENA, 2019).
In 2017, a larger-scale hybrid project of 43 MW of onshore wind, 15 MW of solar
and a relatively small, 2 MW, battery was installed in Australia (IRENA, 2019). In
2018 the first HRES including offshore wind became operational when the 30 MW
Hywind OWF in Scotland was connected to a battery array (IRENA, 2019). The
hybrid system, named Batwind, decreases volatility in power supply by storing energy
in a substation of 1 MW batteries (Equinor, 2018). The world’s first OWE and solar
project is currently under development off Nanri Island, China (Memija, 2023b). This
project comprises 12 MW of offshore wind on three floating semi-submersible
structures which also house solar panels. In addition, fish farms could also be set up in
the centre of each structure. Larger-scale HRES involving offshore wind will require
more advances in technology such as floating solar or wave power. Pilot and
conceptual projects are being undertaken by Scandinavian, British, German, Spanish,
and American companies (Solomin, 2021). Rusu et al (2017) point to the opportunity
for offshore wind HRES in developing countries (OWE in combination with wave
energy), though at the time of writing, the authors found that the cost would have been
prohibitively high.
The adoption of any new energy source will have problems, as does the
acceptance of a new technology, a new medical procedure, or any advance. Human
innovation has a history of overcoming such issues. For example, the use of oxen
20
was superseded by
21
more powerful horses in the ninth century, but that transition was not possible until the
horseshoe was invented (Fouquet, 2010). The same author writes of the sixteenth-
century introduction of chimneys and grates ushering in the switch from wood to coal
for heating. He also notes that new technologies accompanied the transition to fossil
fuels, first seen in the UK. From there the technologies spread globally with the shift
in fuel type. Innovation will continue to be seen to accompany the transfer to
renewable energy sources.
This research aims to tap into the benefits of renewable energy, applying a widely
used practice from O&G, giving renewable energy a boost up the learning and
innovating curve with respect to offshore leasing.
Adoption of Renewable Energy
Nations such as those in the G20 (mostly developed and wealthy) accounted for
85% of global GDP and 66% of global population in 2022 (OECD, 2022). In 2023,
they held 87% of installed renewable energy capacity (calculated from IRENA, 2023),
leaving only 13% for non-G20 (mostly developing) nations. Within the IRENA G20
capacity data, the G20 countries which are considered developed (this includes China)
account for 84% of installed renewable energy capacity. Developing G20 nations only
account for 16%. This focus on developed countries is due to the historical costs
involved in developing a renewable energy industry – costs over and above the
expenditure required to provide energy from fossil fuels at the time. The dominance of
wealthy countries in renewable energy is also due to the need for research and
development (R&D) to generate the technologies needed – expenditure which is out of
reach of many developing countries. E&Y (2021) identify that developed countries
22
must take responsibility for both financing R&D for renewables and assisting
developing countries with financing for renewable energy projects. Bui et al (2022)
point specifically to Vietnam’s potential for OWE but that the country will rely on
technology flow from developed nations. Do et al (2021) speak of Vietnam’s likely
reliance on knowledge and manufacturing from other countries.
Although developing countries lag behind the progress of their wealthy
neighbours, they stand to benefit greatly from renewable energy as they develop,
rather than relying on hydrocarbons. Industrialisation, increased trade, urbanisation,
deforestation, and combatting poverty in developing countries are increasing
contributors to environmental degradation when fueled by hydrocarbons (Masron &
Subramaniam, 2021). An acceleration of renewable energy penetration into those
economies is essential so that those countries do not become the next generation’s
biggest polluters, affecting both local and global environments. For example, in
Africa, the second most populous region in the world (Wittgenstein, 2022), 80% of the
rural population still relies upon candles and firewood for lighting and cooking
(Nalule et al, 2022). Replacement of wood for cooking in Africa is expected to save
US$20-30 billion a year in reducing health problems caused by poor indoor air quality
(Gopalakrishnan). In turn, Cottrell & Falcao (2018) point out that developing and
undeveloped countries are the hardest hit by climate change and stand to benefit from
the energy transition. Welsby et al (2021) indicate that “60% of the oil and fossil
methane gas, and 90% of coal must remain unextracted to keep within a 1.5 deg C
carbon budget”. Yet, between 1999 and 2019, O&G production increased by 12% and
93% respectively in Africa (BP, 2021 & BP, 2010).
23
Despite the potential cost, but recognising that renewable energy is beneficial and
that the country is more exposed to climate change than most, Vietnam has
implemented at least seven policies to encourage renewables or discourage
hydrocarbons (Zimmer et al). As Vietnam is a developing country, it is not bound by
obligations under the Kyoto Protocol, yet it created goals to reduce greenhouse gases
by 2020 and beyond, and policies around carbon tax, emission reduction, green
certificate trading, increasing energy efficiency, phasing out fossil fuel subsidies, and
increasing tax on hydrocarbons (Zimmer et al). By 2022, these had evolved into goals
for emission reductions in 2030 and 2040, 75% power from renewables by 2045, the
phase-out of coal by the 2040s, and to be net-zero by 2050 (Agarwal et al, 2022). In
2022, Vietnam had the third largest renewable energy capacity in Asia, behind much
larger China and India (IRENA, 2023).
Wind energy is seen as having advantages over other renewable energy sources
including ease of implementation, long life of turbines, uncomplicated infrastructure,
and being low-cost (Rabbani et al). As the International Energy Agency (IEA, 2019)
points out, wind energy, and particularly OWE, has less variability than competing
renewable energy sources such as solar. Tidal, wave, and geothermal power have the
advantage over wind of being available around the clock. However, geothermal is
currently cost-prohibitive except in niche settings (Tester et al, 2021) and tidal energy
demonstrations have also suffered the same fate of being too expensive (Chowdry et
al, 2021). Wave power has seen many successful small-scale demonstrations but there
is not yet a commercial-scale park due to technological constraints, prohibitive capital
costs, and high operating costs (Guo & Ringwood, 2021).
24
Compared to fossil fuels, renewable energy is a new industry even in countries
with the longest histories of renewable energy installations. The most developed
example is biofuel ethanol, with a forty-year history since the early 1980s (Cotti &
Skidmore, 2010). In contrast, OWE is one of the newest, in which installed capacity
only reached double-digit MW output at the turn of the twenty-first century (Higgins
& Foley, 2014). Developments and changes to all aspects of the industry are frequent
and common, as in any growth area, providing opportunities for innovation, not only
in the technological and engineering sense but in all facets of the business. As of the
late 2010s, OWE has shifted from being considered a new technology to a “rapidly
maturing” one (IEA, 2019 p15). Nowadays, the new technology related to offshore
wind is floating offshore wind. It has only been considered feasible since 2017 with
the 30 MW Hywind demonstration (pilot) project in Scotland (IEA, 2019). By 2023
Hywind had been joined by three more: 25MW Windfloat Atlantic off Portugal,
50MW Kincardine off Scotland, and 88MW Hywind Tampen, off Norway (Edwards
et al, 2023). In December 2022, construction began in China on what will be the
world’s largest floating wind farm, which at 1GW will have eleven times the capacity
of Hywind Tampen (Xia et al, 2023). Floating OWE is considered to have even more
potential than fixed bottom OWE due to higher wind potential and lower visual and
acoustic effects on human populations further offshore (Barooni, 2023). The authors
point out that since much of the usable wind is located where the seabed is over 60m
deep and/or the bathymetry is complex, floating solutions are required. Constant et al
(2021) confirm this, approximating that 80% of offshore wind sites are at water
depths greater than 60m and Casey (2024) states 70% of USA OWE is only accessible
with
25
floating installations. Barooni et al detail the five types of floating structure that can
be used – interestingly, four of these are taken directly from offshore O&G platform
designs. However, as those authors admit, the costs of floating OWE are higher than
fixed bottom, which are in turn higher than onshore.
This research, with its study of the applicability of an existing lease contract
type, aims to encourage the adoption of one renewable energy source; fixed bottom
OWE. If successful, the applicability to other sources could be demonstrated in future
work.
Offshore Wind
Introduction
Wind energy, and specifically OWE, have enormous potential to provide power
for the global population – eighteen times over - according to the IEA (Yale
Environment 360, 2019). Indeed, the best sites alone could supply more power than
the world consumed in 2019 (IEA, 2019). Wind, together with solar power, will need
to become a central pillar of global energy supply by 2050 if the world is to meet the
net zero roadmap set out by the IEA (GWEC, 2022). Wind will provide 35% of global
power and solar 33%. This includes moving power generation from wind offshore;
there is more available space offshore compared to on land (Do et al, Esteban et al,
2011, Lee et al, 2023). The wind is stronger out to sea (Dahl, 2022), and wind speed
is more constant offshore (Esteban et al). Bigger turbines and farms can be installed
offshore without creating conflict for land use (Esteban et al). As IRENA (2019)
points out, Gigawatt-scale farms can be built offshore, close to population centres. To
achieve the same scale onshore would require over 300 turbines rated at 2.75 MW
26
each (USGS, 2023) vs. 67 offshore turbines of 15 MW each (calculated from Lewis,
2023b) or 56 offshore turbines of 18 MW, prototyped in 2023 (Lewis 2023a). Taller
turbines can be built offshore, which will have a smaller visual and acoustic impact
from land (Soares-Ramos et al, 2020) and are expected to increase the efficiency of
wind energy (Chen & Su, 2022). Visual and noise impacts are two of society’s
objections to onshore wind farms, as are decreases in property values, destruction of
views, blocking of light, and diminished access to nature (Westlund & Wilhelmsson,
2021). All these concerns can be mitigated, or addressed entirely, by moving wind
farms offshore. However, Dwyer and Bidwell (2019) caution that local communities
must still be properly engaged for offshore installations. In fact, tourists to Block
Island, offshore Rhode Island, USA, view the wind farm positively and are interested
in seeing it (Bidwell, 2022). Residents, when surveyed and interviewed before
installation, at first operations, and a year later, became more positively disposed to
the OWF (Bingaman et al, 2023).
In their bibliometric analysis, Chen & Su find OWE has both positive and
negative impacts on marine life populations. On the negative side, transportation,
piling, seabed disturbance, and noise can cause sea life to avoid the area. However,
once in place, on the positive side, the turbine bases can act as artificial reefs and
attract sea life. This has long been seen around O&G rigs and facilities (Ajemian et al
2015). To achieve the global temperature-rise limitation of 1.5 degrees Celsius,
onshore wind will need to scale up by a factor of three by 2030 and a factor of nine
by 2050 (IRENA, 2019). Offshore wind, being less prevalent today, has further to go:
a ten-fold increase by 2030 and over forty times by 2050.
27
Offshore Wind Usage and Policy Today
In 2022, according to IRENA (2023), OWE capacity was split 51:49 between
Asia and Europe. Within Europe, the split is 55% EU to 45% UK, with the UK
holding almost 70% more capacity than the next individual country, Germany. In
Asia, China holds 94% of the capacity, with more than double the UK’s. The US lags
with 0.07% of the global OWE share though in 2024 (BOEM) there are thirty-nine
active federal offshore leases at various stages of analysis, permitting or development.
In 2022, the first auction of seabed in four years was completed and garnered record
bids of US$4.4bn, ten times that of prior auctions; and encouragingly, more than
recent O&G leasing auctions (Lewis, 2022). The 2024 five-year offshore wind leasing
schedule (BOEM) envisages twelve more lease sales to continue to support the goals
of 30GW of fixed bottom offshore wind by 2030 and 15 GW of floating offshore
wind by 2035. Being a follower into a new technology may even prove to be prudent.
Hayashi et al (2018) opined that China has rushed the building of wind generation
capacity and has neglected to build a strong foundation including quality
infrastructure, knowledge, and a skilled workforce for the future. Further, as
Westwood (2022) points out, China will be challenged to add capacity at the same
rate after the expiration of governmental subsidies for offshore wind at the end of
2021.
IRENA (2023) figures show that offshore wind capacity additions increased 29% in
2019, 52% in 2020, and a huge 194% in 2021 to beat the expiry. The same data shows
a modest, but non-zero capacity addition in 2022 of 15% which matches the average
rate of growth in onshore wind from 2016 to 2022.
28
Taiwan offers an example of a country which realises the key role offshore wind
can play in the energy transition (Yue et al, 2021). Today, power generation is from
hydrocarbons (coal and natural gas), 98% of which are imported, and nuclear. The
Government underwent a policy shift in 2016 towards nuclear and natural gas, but the
nuclear expansion has halted since the dangers were realised post-Fukushima (Yue et
al). Now the Taiwanese Government is shifting towards offshore wind, realising the
strong offshore potential, and has specified thirty-one OWFs that will start to replace
the other energy sources (Yue et al). The authors demonstrate that nuclear and coal
can be replaced by OWE by 2025 and 2032 respectively, and natural gas can be
replaced by 2040. Similarly, Hong Kong, which imports most of its hydrocarbon fuel
for power from mainland China, sees an opportunity to decrease its carbon footprint
and achieve supply resilience by taking advantage of the good wind potential in the
surrounding waters (Delina, 2022).
France is an interesting case, since 80% of its power comes from nuclear energy,
15% from hydro, and very little from fossil fuels (Desvalles et al, 2023). Other forms
of energy, including offshore wind, are not welcomed due to the large footprint of the
installation per unit of power produced. The authors point out that conversely, France
does not reject the concept of OWE, and the country provides one-third of Europe’s
manufacturing capacity for turbines. However, most stakeholders do not see a place
for offshore wind in France’s energy mix.
Most countries will also face challenges from aging or insufficient grid
infrastructure e.g., Vietnam, China, Germany (Do et al), and the USA (Smith et al,
2019) though if there is the will, there is time to rectify this issue alongside the
29
building of large offshore wind installations. In 2022 (IRENA, 2023) offshore wind
comprised 7% of total wind energy and less than 2% of renewable energy – there is
time to address infrastructure issues. This author is not attempting to minimise this
critical issue, but to leave its resolution to others.
There are currently very few developing countries engaged in offshore wind
activity, due to the historical costs and requirements for subsidisation. Vietnam is the
only example of modest active offshore wind with small coastal power plants serving
as pilot projects to test the area (Tsuge et al, 2023). The report does highlight that the
testing has been successful and there are plans for a 500 MW to 1 GW farm by 2030.
2023 also sees the first leasing of four tracts of seabed off India (Times of India, 2023)
for 4 GW of power generation potential. The article mentions ten further tracts to be
auctioned in the future for another 10 GW of generation. This adds to the 42 GW of
onshore wind currently active, and 58 GW planned by 2030 – to make up nearly a
quarter of India’s ambition for 500 GW of renewable energy by 2030. Brazil is leasing
very successfully for offshore wind, having received 71 applications for projects by
late 2022 with a total proposed capacity of 177 GW, including large 2 GW and 3 GW
sites (Buljan, 2023).
None of these leasing efforts use a contract modelled on a PSA. This research
aims to widen the options for governments wishing to lease seabed for offshore wind
projects.
Global Wind Potential
OWE is one of the most rapidly developing renewable energy sources (Dahl et al,
2022). Consider that in 1991, the first OWF became operational in Denmark, with a
30
capacity of merely 5 MW of power (Gaudiosi, 1996). In 2022 OWE capacity was over
twelve thousand times that, at 63,200 MW (IRENA, 2023). One hundred OWFs have
been put in place between 2000 and 2022, and a thousand more are in the development
stages (Chen & Su).
The strongest resources in terms of wind potential are to be found in the
temperate zones offshore Northwest Europe, Northern USA and Canada, China,
Southern Australasia, Southern and Northern Latin America, Southern Africa (Weiss,
2018); Northwest and Northeast Africa (Soares et al, 2020); and Eastern Africa
(Choti & Xydis, 2022). The best geographic locations can be seen in Figures 1 and 2
below, in which the highest potential areas are shaded in yellow/green (Figure 1) and
yellow- orange-red (Figure 2):

Since only two of those areas, Northwest Europe and China, have any significant
OWE capacity to date, there is much scope for expansion. Eicke et al (2022) posit that
by 2050 60% of offshore wind capacity will be sited in Asia, 22% in Europe, and 16%
in North America. This leaves little for Africa and Latin America, which both have
wind potential and in the case of Africa, a large population. The continent is predicted
to hold 25% of the world’s population by 2050 (Wittgenstein, 2022). The World Bank
(2019a) also recognises in its programme the opportunity to fast-track the adoption of
OWE in developing countries. However, the programme is about raising awareness,
assessing potential, and identifying challenges rather than installing wind farms.
The closer wind farms are to population centres the better, as power attenuates
when transported (IEA, 2014), and the cost to build or upgrade infrastructure is lower.
There is a calculable tradeoff between placing wind farms in the areas of high
potential that are further from the markets and siting them close to large cities in
lower wind potential areas (Lamy et al, 2016). The authors state that it is important to
32
study
33
this trade-off – they demonstrate that in the mid-west of the USA, moving to an area
with a wind capacity of 43% vs. 40%, extra infrastructure capital expenditure of
US$1.4 billion can be made before reaching the breakeven point. The authors also
point to the relevance of these calculations in China, where the best wind potential is
in the Northwest, but the demand is in the East. This argument can be extrapolated to
any country or continent with higher wind potential far from the demand centres.
Lamy et al were concerned with onshore wind power but the point is also relevant to
offshore wind. 84% of countries have a coastline (Rusu et al), and 41% of the global
population live within 100km of a coast. In over half of the world’s coastal
countries, 80-100% of their population lives within 100km of the coast (Martinez et
al, 2007). There is a large market for power from offshore wind.
A diverse set of organisations see a strong future for wind power’s penetration
into the global energy mix (IRENA, 2019). Agencies such as IRENA, the IEA, the
consultancy BNEF, energy companies such as Equinor, DNV, and Shell, and the
NGO Greenpeace see wind providing 21-35% of global power by 2050 under current
policies (IRENA, 2019). This share will be even higher if policies are amended to
limit global temperature increase to 1.5 degrees Celsius.
Learning from the Oil and Gas Industry
The offshore wind industry has much in common with the offshore O&G industry
such that offshore wind can make quick advances by emulating or using O&G
resources. Edwards & Dalry (2011) find six common technologies; including offshore
construction vessels, remote-operated vehicles, and dynamic positioning systems, are
directly relevant and transferable to offshore wind operations. The authors also found
34
in their interviews that the supply chain has significant similarities, but they caution
against one O&G practice, namely sub-contracting for servicing and maintenance, due
to the risks introduced by not maintaining control of operations. Finally, they advocate
for the adoption of one practice; cooperation on technology, research, and
development, which has been a key success factor in O&G. At the time of writing,
offshore wind technologies had been developed in secret, and opportunities to
collaborate were being lost.
O&G companies have recognised the similarities, and many have entered the
OWE space. Mathews et al (2022) point to TotalEnergies of France, BP of the UK,
Equinor of Norway, and CNOOC of China – all global major O&G companies, who
have either entered joint ventures to build OWFs or have started their own OWE
divisions. In addition, service companies are transitioning to gain offshore wind
capabilities; thus, all these companies are engaging in Schumpeter’s creative
destruction process and replacing their own O&G business with renewable energy
(Mathews et al).
It is due to these similarities that offshore wind has been selected as the
renewable energy source for this research and as a topic of study for the application
of PSA-like terms. OWFs are the most similar renewable energy installation to
offshore O&G platforms, to which PSAs currently apply. This researcher does not try
to claim that OWE can replace O&G – merely that offshore wind can provide power
where traditionally hydrocarbons would be used – and that best practices from the
O&G industry could potentially apply in leasing contract terms.
35
Hydrocarbon Contract Terms
Global hydrocarbon production is governed by fiscal systems which are intended
to lay out the contractual rights and obligations between the foreign investor (known
as the Contractor) and the host Government; and provide the fiscal calculations for
the allocation of revenue (Johnston). In this sense, fiscal refers to streams of
government revenue; these could be traditional taxes or non-tax cash payments
(Sunley, 2003).
There are two primary fiscal systems, the Concession Agreement (CA) and the PSA
(Løvås & Osmundsen, 2009). Other less-used systems include a standalone strategy in
which foreign investment is not sought (Mohamed et al, 2022a), and Service
Contracts, which are unpopular with foreign investors who merely receive a fee for
the work and do not share in the upside; nor does the system encourage marginal
projects (Johnston & Johnston).
A CA is a long-term contract giving the Contractor sole right to operate on the
concession area in question whilst only paying Royalty and Taxes to the Government.
Royalty and tax rates are set at the region or country level and rarely vary by
concession. The CA system is viewed as skewed towards the Contractor (Løvås &
Osmundsen) for two reasons: it does not allow for Government participation in the
project, and the Contractor owns the mineral resources. Additionally, in a CA, the
Government can change the fiscal terms at any time as they are area-wide and not
included in the contract (McClean, 2023). This creates uncertainty for the Contractor
in projects that may span 40 years.
Contractual systems, of which PSAs are a modern example, date back to early
1800s France and are rooted in the idea that the Government should retain ownership
36
of mineral resources for the benefit of the citizenry (Kaiser, 2006). The PSA was first
used in the 1960s in Indonesia, at the time of the country’s independence, in response
to local hostility towards the foreign oil companies who held CAs (Bindemann, 1999)
and a desire by the Government for more control of, and benefit from, their own
resources (Hassan et al, 2022). The critics were satisfied with the new contract as the
Government retained control of the resources. Contractors were initially hesitant but
since then PSAs have spread to every continent. The PSA, being a negotiated contract,
offers more flexibility on a project-by-project basis than a CA which is governed by
the industry rules and regulations in force at the time (Hassan et al).
Key Goals of Production Sharing Agreements
The key goals of a PSA offered by a government include attracting skilled
foreign investors in the form of energy companies, facilitating skill and knowledge
transfer to host country workers and companies, providing revenue for the
Government and an acceptable rate of return for the Contractor (Dirani et al, 2021).
Many developing countries lack the technical or financial capability to extract
hydrocarbons and hence, cannot create value from them (Dirani), and PSAs provide a
solution in several ways (McClean). In fact, the PSA is the most prevalent form of
O&G leasing contract found in developing countries (Hassan et al). The Government
keeps ownership of the mineral resources and through the leasing agreement (the
PSA) appoints the Contractor to operate the project. The Government shifts the risk of
an unsuccessful project to the Contractor, who pays all the capital and operating costs.
In return, the Government allows the Contractor to recover those costs from a
successful project and share in the production and financial success (Sunley).
37
This research aims to investigate the utility of these points outside the context of
O&G by applying them to OWE.
National Oil Companies
Unlike any other hydrocarbon leasing contract, the PSA is frequently seen in
conjunction with the establishment of a national oil company (NOC) to participate in
the projects and receive the skill and knowledge transfer. Tracy et al (2011) discuss
several reasons why governments choose to set up a NOC. These include socio-
economic goals such as increasing employment, building infrastructure, and
improving technological capacity. These goals also include minimising government
bureaucracy - through its participation, the NOC monitors the private companies
managing projects, rather than needing a government department for oversight.
Hassan et al state that the joint committee of the international oil company (IOC) and
NOC are critically important in monitoring the operations of an oil or gas field. Also,
a NOC, through its participation as an equity holder and partner in a project, can gain
economic rent as a contractual party and increase the amount of cash that flows to the
Government above pure government receipts from Royalty, Profit Share, and Taxes
(Hassan et al). NOCs were prevalent throughout the developed world in the last
century – there were over a hundred created between 1920 and 2003 (McPherson,
2003). The early goals of the NOCs were nationalism, energy supply security (direct
control, not merely through legislation), job creation, manufacturing capacity and
infrastructure building, and policy implementation (Tracy et al, McPherson), and those
goals still hold for today’s NOCs.
38
It is true that NOCs frequently manage the downstream industry alone, but they
rarely attempt exploration or production (upstream) projects without an IOC partner
due to the sheer costs and risks (McPherson). The fact that developing countries (the
typical users of PSAs) have neither the needed expertise nor capital to run an upstream
O&G project (Hassan et al) makes the IOC-NOC partnership engendered by the PSA a
valuable one. Indeed, NOCs are expected to gain knowledge and expertise from the
IOCs through these partnerships, the governance of which is written into the PSA
contract (McPherson). The same is true for infrastructure building, job creation, local
manufacturing capacity improvements (all known as local content), training,
scholarships, and grants (Pongsiri). The Government also benefits by having a degree
of control over operations through the NOC and it may retain some mineral resources
for local use or sale (Majd, 2020).
Antolin et al’s case study (2013) contrasts Bolivia’s and Brazil’s NOCs and
concludes that a functional NOC (such as Petrobras, in Brazil) can improve the
country’s hydrocarbon industry performance by gaining better control of the country’s
natural resources compared to a country with no NOC. Brazil has also improved
innovation and the use of local suppliers in the industry through its contract terms
requiring those activities of foreign investors, in partnership with the NOC. The
authors also point to the fact that an NOC with strong technical, operational, and
financial capabilities will perform as a strong regulator and make that country
attractive to foreign investment. The converse is that a less capable NOC (such as
YPFB, in Bolivia) can lead to harsher regulations and fiscal terms and in turn,
discourage foreign investment (Antolin et al).
39
In 2003 NOCs controlled 90% of the world's oil reserves and 73% of the
production (McPherson) and are still widely seen in developing countries. Of the 82
countries with PSAs, 56 (68%) have NOCs which participate alongside IOCs in O&G
exploration, development, and/or production (Wood Mackenzie). From the same data
source, 51 (91%) of PSA-using countries with NOCs are developing countries.
Conversely, NOCs and PSAs are rarely seen in developed countries (only Brunei,
Thailand, Malaysia, Oman, and Trinidad & Tobago), most preferring CAs and
government oversight but not participation in the projects. The use of PSAs and
NOCs in the three aforementioned Southeast Asian countries dates back to the
proliferation of PSAs in the area after their invention by neighbouring Indonesia – at a
time when they were developing countries themselves. Since the early days, some
wealthy nations - the UK, France, Norway, Spain, Italy, Belgium, and others have
chosen to partially or fully privatise their NOCs, (Tracy et al) and no longer consider
the reasons for retaining a NOC important enough to bear the cost of running the
company.
This research intends to examine whether these advantages of NOCs within a
PSA framework could be applied to OWE.
Revenue and Profit Sharing
Government revenue in CAs comes in the form of bonuses (for access), royalty,
rentals (a minute portion of the total cash flow), and taxes. The PSA, on the other
hand, is designed to share the profit between the Government, who is the resource
owner, and the Contractor who takes on the expense and the risk of exploring for,
developing, and producing the hydrocarbons (Luo & Yan). Over decades PSAs have
been developed and refined and are considered the most functional method of sharing
40
wealth over a broad range of project characteristics (Johnston & Johnston) such as
hydrocarbon deposit size, cost to develop, hydrocarbon price, geologic risk, and
others. Costs and risks may be borne by both parties when the Government
participates in the projects through its NOC, or solely by the Contractor.
PSAs are designed to provide the resource owner income at various stages of the
project. This includes royalty from gross revenue, a share of the profits after costs
have been repaid to the Contractor, and taxes; that is corporate income tax plus, on
occasion, a special petroleum tax, on net income (Johnston & Johnston). The
calculation of the royalty, the fund from which costs can be recovered, the profit split,
and the special petroleum tax are often flexible and depend on prevailing hydrocarbon
market price, hydrocarbon resource size, project rate of return, or other factors. This
flexibility ensures that an economically marginal project can still be profitably
developed by the company. It also ensures that in the case of a hugely profitable
project, it is the resource owner and not the Contractor who receives most of the
excess profits above a certain rate of return to the company. In a CA, the resource
owner often financially benefits only from a royalty on gross revenue and corporate
taxes and does not share directly in the profits.
Rarely have countries switched between fiscal system types, but Brazil is one
example. The first contracts on offer to foreign companies, from 1995, were CAs of
the type used in developed countries such as the USA, UK, and Norway, and were
inspired by those systems (La Macchia, 2017). However, despite world-class
geology, Brazil was not able to attract foreign super-majors’ interest as it hoped. In
2010 the country switched to PSAs which were intended to be more flexible under
differing
41
project conditions. They also permitted the NOC, Petrobras, to participate alongside
the foreign companies in the projects and enhance its technical capabilities. Brazil
now has fifteen areas leased under PSAs (ANP, 2023).
One objective of this research is to study whether this revenue and profit-sharing
mechanism could have potential for OWE.
PSA Fiscal Terms
The four key terms in a PSA that affect the division of revenue are Royalty, Cost
Recovery, Profit Oil/Gas, and Tax (Kaiser & Pulispher, 2005a; Bindemann, 1999;
Hassan et al). There may be other minor terms, either legislated or negotiated, such as
signature and production bonuses, value-added or sales taxes, special petroleum taxes,
import/export duties, uplifts, and rentals. Cost Recovery, Profit Oil/Gas, and Tax are
common to almost every PSA. These three terms, together with Royalty, are found in
70% of global PSAs and have the largest effect on the division of revenue (Wood
Mackenzie).
Royalty is calculated as a percentage of the gross revenue. The rate may be a flat
percentage, or it may vary with the life of the project, production rate, cumulative
production, or other factors such as project return or oil quality. (Wood Mackenzie).
Royalty is popular with Governments as it provides up-front revenue as soon as a
project commences production, but it can be regressive, rendering marginal O&G
fields uneconomic as Royalty is paid before costs are covered (Tordo, 2007), hence its
absence in 30% of PSAs (Wood Mackenzie).
Cost Recovery allows the Contractor to be repaid for capital and operating costs
from the post-Royalty Revenue. A Cost Recovery Ceiling (CRC) of less than 100% is
42
often set so that costs can only be recovered from a portion of the post-Royalty
Revenue. This ceiling is above 50% in 90% of PSAs (Wood Mackenzie). A ceiling
much below 100% can cause a regime to be regressive but does allow the Government
earlier cash flow than from Profit Oil/Gas or Corporate Income Tax (McClean).
Unrecovered costs each year are carried forward.
The Profit Oil/Gas Split provides the next division of revenue between Contractor
and Government. The Revenue after Royalty and Cost Recovery is split between the
two parties. The Profit Split may be a fixed percentage or on a sliding scale with
production or other factors. It is popular to base Profit Split on an “R-factor”, which is
based on project return – 35 out of 81 (43%) countries employ it (Wood Mackenzie).
This allows good flexibility to support marginal projects but also permits the
Government to enjoy most of the upside from highly profitable projects. Profit Split is
a progressive term if structured well, encouraging marginal projects by directing most
of that profit to the Contractor; but providing a windfall to the Government in the case
of a highly successful project.
Income Tax is usually legislated and often applied at the same rates to all
industries and all companies in a country. Rates can change as tax legislation changes
unless grandfathered into the PSA contract. Tax rates may be flat or progressive, with
higher rates for higher levels of net income. Countries wishing to tax hydrocarbons at
a higher rate than other industries will enact a resource rent tax, or special petroleum
tax (SPT), payable in addition (Sunley). Countries that use PSAs rather than CAs
make use of SPTs less often – there is no need, as the Government shares in the profit
through the Profit Split. CA users must tax the hydrocarbon industry at higher rates
43
than other businesses to gain a larger share of the profit. This special tax revenue
comes at a later stage of the project than the profit-shared cash flows from a PSA
(Sunley). Taxes can also be mitigated by the Contractor by depreciation and
deductions, potentially limiting the flow to the Government. Globally, only 16% of
PSAs include SPT whereas 41% of CA regimes include it.
Other more minor financial terms commonly found in PSAs and worth
mentioning include rentals and bonuses. Rentals are small payments made annually
based on leased acreage, and bonuses are paid at the time of leasing but are typically
only found in highly prospective areas (Sunley). Energy companies are not willing to
pay multi-million-dollar bonuses for risky land grabs, nor where there is little
competition for the land (Sunley). One final term also seen in PSAs is Uplift (Sunley,
Tordo). In this researcher’s experience, it is often used in new areas – new
geographies, new markets, new geologies, and new technologies. Uplift is a multiplier
applied to costs before Cost Recovery to encourage the Contractor to make the
necessary investments. The Uplift allows the Contractor to recover costs more quickly
and gain from the time value of money. This term would not be seen in a highly
profitable or well-established area but is often included in contracts in geologically
risky or technologically expensive areas such as marginal deepwater fields in Angola
(Wood Mackenzie). Uplift has utility in this research as applied to OWE in
developing countries: a new technology in new geographies.
Non-fiscal terms to be found in PSAs which nonetheless affect the project cash
flow include local content obligations and domestic market obligations (DMO). In the
former, the Contractor must provide training for, or employ nationals, or use local
44
goods and services (Tordo, Tordo et al). In the latter, the Contractor must sell a
proportion of the production to the local market, often at a discounted price
(Bindemann).
Offshore Wind Terms
Subsidies and Incentives
Until the early 2020s, contract fiscal terms governing wind energy projects were
based on the Government offering subsidies and incentives to develop projects.
Examples are found in Europe (Higgins & Foley, 2014; Reichardt & Rogge, 2016;
Fristrup, 2003), Asia (Anwar & Mulyadi, 2011) and the USA (Anwar & Mulyadi,
Mormann, 2014). In Europe and Asia, which have producing wind farms, these terms
are collectively known as feed-in tariffs (FIT) which are part of a policy that mandates
energy utilities to pay a premium to producers that generate electricity from renewable
sources (Mendonça, 2012). They are found in two forms: feed-in premia and feed-in
prices (Alolo et al, 2020). A feed-in premium in offshore wind is a government-
provided premium above the market sales price of power whereas a feed-in price is a
government-guaranteed sales price for power, also known as a contract for differences
(CfD). Burer & Wustenhagen (2009) found in a survey of sixty investment
professionals that feed-in prices are the preferred subsidy method, and Polzin et al
(2019) confirmed this in a review of ninety-six studies on the impact of policy on key
investment metrics. However, the efficacy of feed-in premia is debated, with Alolo et
al (2020) finding it ineffective based on discounted cash flow modelling in 27 EU
countries whereas Reichardt & Rogge (2015) had previously found it to be effective
in
45
Germany. Bunn & Yusupov (2015) assert that feed-in premia will become ineffective
as wind power supply exceeds demand.
Community Benefits and Compensation to Local Residents
In several countries, provisions are made to compensate local communities for
the burdens felt living with a wind farm, but examples for OWFs are rare (Rudolph et
al, 2015). Most are related to onshore wind farms which have been extant for longer
and are more likely to inconvenience local communities. In Denmark, two schemes
are underway applying to both onshore and offshore wind; a third was halted after ten
years in 2018. The first is a property-value loss scheme and the second is a co-
ownership scheme (Jorgensen et al, 2020). The authors describe the former as
financial compensation for diminished property value due to being located near a
wind farm, and the latter as financial returns through holding an equity share in the
business. The latter can be offered to a wider community than the former which is
constrained to neighbouring properties. The authors find that these purely financial
schemes have limited success unless alongside recognition, another key dimension of
environmental fairness.
Financial assistance was also the most common benefit encountered by Rudolph
et al in the UK and the Netherlands. The UK is considered a leader in community
benefits from onshore wind in that GBP5,000 must be spent per MW of installed
capacity (RenewableUK, 2013). However, offshore, the amounts were often less
generous, and participation was considered voluntary (Glasson, 2020). As well as
funds which provide financial support to the community, schemes which directly
46
provide apprenticeships and education were seen in the UK. Ownership in the facility
was seen by the same authors in Germany and the Netherlands.
In 2014 (Rudolph et al) the first community benefit agreements in the USA were
seen during leasing off Massachusetts, but these did not specify up-front amounts or
activities which would aid the local population. The bids in California’s first offshore
wind lease round in 2022 (Ayoub, 2023) also included community benefit agreements,
this time with more specific terms, supporting initiatives for workforce training and
supply chain development. This last example, having specific development goals and
not just financial support, is akin to some of the terms seen in PSAs in O&G in
developing countries.
The traditional PSA, as described previously, mandates specific benefits that
must be built for the host country such as infrastructure. It also obliges funds, such as
for training and education, which are financial benefits. A PSA, being an enduring
contract, would provide these benefits to the communities for the life of the wind
farm. The communities would be protected from a change in legislation that might
cause a loss of those advantages or compensation, the same way PSAs protect those
rights attached to O&G projects.
There are no national energy companies to mirror the NOCs in the O&G industry,
though two developed country NOCs, Equinor and Ørsted, have diversified into OWE.
Both companies are operators and are not in the position of needing to learn from
experienced operators through a PSA-type arrangement. There are no instances of
developing country governments directly benefitting from OWE in the manner that
they do through PSAs in the hydrocarbon sector.
47
Existing and Mooted Leasing Mechanisms
Laido et al (2022) make the important point that providing developers of OWFs
access to the seabed is a crucial piece of the puzzle. Gonzalez et al (2020) performed
case studies on the offshore wind leasing mechanism in Denmark, the UK, and
Germany. From 2013 to 2019 those countries were the top offshore wind power
generators in Europe; even in 2022, they are in the top four, joined by the Netherlands
(IRENA, 2023). All were characterised by a mixture of tenders (bidding rounds) and
direct negotiation, by multi-phase licences corresponding to different activities, and
historically, by FIT or CfD incentives. Government participation in the projects was
not mentioned, indeed, none of these countries’ governments participates in O&G
projects. Last century, Denmark and the UK had state O&G companies, now known
by the names Ørsted and BP. Ørsted is no longer active in O&G and BP has been
privatised. Interestingly, both are significant players in offshore wind today.
Community benefits as discussed in the previous section do feature in the leasing
practices of all three of these countries.
In China the approach has been uncoordinated, involving numerous ministries
and agencies (deCastro et al, 2019) making the meteoric rise in installed capacity
even more remarkable. Hybrid systems of approvals exist, involving municipal,
regional, and central energy departments, and long-range plans are made at the county
and prefecture levels (Hughes et al, 2022). As such, this researcher has not been able
to elucidate a clear picture of the leasing mechanism(s) in use. As outlined later in the
section “Beyond Subsidies,” FITs were in existence until late 2021 but discussion of
48
the type of lease – whether or not it mirrors an O&G CA-type agreement - does not
appear to be extant.
The USA has been slow to adopt OWE (Firestone et al, 2015). There was a push
in 2005 with the US Energy Policy Act which required the Department of the Interior
to devise a leasing system for wind energy in offshore waters and they had a leasing
mechanism in place by 2009 (Firestone et al). By late 2021 (Comay & Clarke, 2021)
only one commercial-scale (though small, at only five turbines) OWF was operational
at Block Island, offshore Rhode Island. It is in state waters, not federal. This is despite
leasing having taken place in federal waters annually from 2012 to 2023 except in
2020 and 2021 offshore Delaware, Maryland, Massachusetts, New Jersey, New York,
North Carolina, Virginia, and California (BOEM, 2024). The first Gulf of Mexico
OWFs were approved in 2024 (Budin, 2024) in Louisiana’s state waters; the state
recognised that although their economy has been heavily dependent on O&G for
decades, renewables will play a large part in their energy supply future. These USA
lease auctions are modelled closely on the offshore O&G lease sales which have been
ongoing since 1954. Firestone et al attribute this slow start for OWE to three factors.
First, the burdensome offshore O&G regulatory regime being inappropriately applied
to offshore wind – it is onerous in order to protect against the potential catastrophic
disasters that can beset O&G installations – which do not apply to wind farms. A fit-
for-purpose regulatory regime would be more desirable. Second, the leases place an
emphasis on up-front lease bonuses committed at the auction, which can have a
regressive effect on the project's economics. A preferable system would be to extract
royalties from the revenue of the operational OWF, though the government would
wait
49
longer for their portion of the revenue. Third, although the USA had an interest in
OWE, it did not put strong policies in place at the time to encourage offshore wind
over hydrocarbon energy sources.
The USA has chosen not to offer price-supporting tariffs like China and Europe
have. Instead (Energy.gov, 2023), tax credits are available to both onshore and
offshore wind farms. Three types of credit reduce corporate income tax burden; based
on generation from the OWF, capital expenditures made, and power capacity built.
This method has the least regressive effect on project economics but is coupled with
highly regressive up-front lease bonuses.
A notable fact about all the leases offshore USA is this payment of large up-front
cash sums. The five leases in the 2022 California bid round went for US$757MM
(Ayoub) and the sale offshore New York and New Jersey in the same year attracted
bids of US$4.37 billion (Volcovici, 2022). The author points out that one advantage to
the up-front sums is that the money goes into the Treasury and benefits taxpayers.
However, marginal projects can be damaged by high up-front payments, and in the
future less-promising areas may not receive any bids. A contract such as a PSA, where
less revenue flows to the government initially, encourages marginal projects. If the
PSA is structured correctly, the government can more than make up for forgoing early
cash by taking the largest portion of the upside later in a successful project (Mohamed
et al, 2022a). Naturally, no one gains revenue from a project that does not go ahead
because the contract terms inhibit it economically.
With respect to offshore wind California could be compared to a developing
economy for the following reasons. It has no local supply chain like the East Coast of
50
the USA, there are no power purchase agreements (PPA) in place at the time of
bidding to ensure sales price, the permitting process is complex, and there is a lack of
grid infrastructure (Ayoub). Add those factors to the need for floating OWFs which
are more expensive, risky, and based on much newer technology than fixed-bottom
farms and it is a wonder there are any interested developers. There were bids,
however, albeit lower than East Coast bids. This illustrates that even in new and
difficult areas, there is a desire to build OWFs when the conditions are promising.
The USA’s government has no desire to get involved in the building or operating of
offshore wind projects – nor do they in O&G projects. The only area in which they
may choose to involve themselves is upgrading the grid (Comay et al), as it is
typically multi-state infrastructure. A leasing model which contained a NOC (or
NEC) would therefore not suit the USA.
Australia and New Zealand are even newer to OWE than the USA. Australia has
leased only one area to date (Coull et al, 2022). The leasing regime comprises three
licence types: exploratory, feasibility, and commercial. The lease in question was
granted in 2019 as an exploratory licence, and the developers hope to move it to the
feasibility phase in 2023. The plan is to begin construction in the mid-2020s for first
power delivery in 2030 (Star of the South, 2023). The up-front payment for these
licences has not been published - and the licence was designated rather than subject to
a bidding process. The wind farm proposed on the acreage will have a capacity of over
2 GW and involve 250 turbines, over double the capacity of the average farm starting
up in 2020-2022. Rapid increases in capacity and technology should be expected in a
maturing industry. Australia recognises the positives of offshore wind in terms of
51
reliability (relative to onshore wind and solar) and the fact it will be low-cost by 2030.
It sees as an advantage the ability to build OWFs near demand centres (coastal cities),
and the possibility to transition O&G workers to the new energy installations. Rispler
et al (2022) found that at the lower end of cost estimates given for future installations,
OWE would not only displace hydrocarbons but also onshore wind and solar. The
authors suggest that although net zero is a goal for 2050, due to the difficulties in
replacing some uses of energy with clean sources, in Australia, heating and electricity
must be net zero by 2035 to 2037. This leasing regime, like the USA and Europe, does
not offer the Government a chance to participate in the project and offers revenue only
at the bidding stage, and in taxation of the Contractor as a going concern. No mention
was made of community benefits. Perhaps no coincidence that Australia also uses CAs
for O&G leasing (Wood Mackenzie).
New Zealand realises it has great wind potential and considerable coastline per
capita. The country is currently designing its regime for OWE (Coull et al) which will
partly be based on best practices from the O&G industry - but with changes where
merited (unlike the USA). The country is partly looking to Australia’s regime for
ideas. New Zealand is cognisant of the issues faced by offshore wind and is ready to
address them (Venture Taranaki, 2020). It realises transition is needed, which involves
electrification, and as the population and the economy grow, power demand will
double in 30 years. The intermittency can be offset with hydro generation which is
already established in the country. The need for grid upgrade is acknowledged in all
but the most modest OWE scenario. New Zealand is looking to the future with
innovation – realising it has wind potential that could outstrip domestic demand,
52
Venture Taranaki outlines the idea of power storage via hydrogen. Although the initial
wind farms in the study are modest, at 200 MW to 800 MW, the two areas in the study
could deliver 2.4 GW to 12 GW if fully developed - this higher number matches the
UK’s current operational capacity. Like Australia, no mention is made of community
benefits or an option for the Government to participate – and New Zealand also uses a
CA regime for its O&G leasing.
In 2020, Gonzalez et al contributed to the design of the offshore wind leasing
regime in Brazil with their paper combining the current practices for offshore wind
leasing in Europe with the various regimes in use in the Brazilian O&G sector. Their
suggestion was akin to a CA. Indeed, in 2022, the regulatory framework was passed
into law (Palmigiani, 2022) and uses an O&G-like CA with a signature bonus payable
up front, a Royalty on gross revenue, and potentially corporate income taxes if the
company is financially successful. According to Palmigiani, the bonus and Royalty
system was criticised as it may hinder investments, and the Royalty rate had to be
reduced before the regime passed into law. There is no evidence that a more
progressive PSA-like system with the sharing of profit after costs was considered.
There is also no mention of non-financial benefits such as seen in PSAs.
Other countries preparing for their first leasing for OWE include Norway,
Lithuania, Uruguay, Portugal, Colombia, Estonia, and Ireland (Emanuel, 2023), and
promisingly, one of those, Colombia, is a developing nation.
This research aspires to provide an alternative to the O&G CA-type leasing
mechanisms seen above; one that may be of special interest to developing countries,
the primary users of PSAs. It will quantitatively investigate applying O&G PSA
53
contract terms to an OWF and through qualitative enquiry will uncover the most
important provisions of the PSA.
Power Purchase Agreements
A PPA governs the relationship between the seller of power (the generator) and
the buyer (the utility company), and covers construction, operations, maintenance,
interconnection to the grid, and any third-party involvement in the project (Bruck et
al, 2018). These factors contribute to the cost of power generation which must be
covered (plus a rate of return) by the buyer (Bruck et al). PPAs are on the rise in
conjunction with offshore wind globally and commonly encountered in the USA,
Europe, and Latin America (Bruck et al). They provide more certainty to the project
economics by setting a fixed sales price. Though as Bruck et al point out, uncertainty
still exists for the seller in two scenarios. First, if their OWF underperforms they may
have to purchase power on the spot market to fulfil commitments. Second, if the buyer
exercises their right to cap their power offtake, and the seller cannot sell the excess
power, it drives up the seller’s per unit costs.
PPAs are often seen in combination with renewable portfolio standards (RPS) in
which a government sets a percentage of power nationally that must be obtained from
renewable energy sources. The PPA allows the buyer to cap the amount of electricity
purchased from the renewable sources in order to limit exposure to often higher prices.
Hydrocarbon and nuclear power remain cheaper in some situations, and certainly were
historically.
The PPA is downstream of the generator’s leasing of the land or seabed on which
to site the wind farm. A generator could lease from a government under a PSA
54
arrangement which divides the revenue between the resource owner (Government) and
the operator of the OWF (Contractor). The Contractor could then enter a PPA with a
buyer to increase the sales price certainty. The Government, through its NEC, could
still participate in the project and increase its technical capabilities. Hence, a PPA
could be used in conjunction with PSA-like terms for an OWF. This research assumes
a variable price for power; the addition of a PPA would simply remove some of that
price uncertainty and could be the subject of future research.
Beyond Subsidies
Oil and Gas Industry
Incentives such as tax credits have indeed been available to the hydrocarbon
industry since its inception. Countries such as Norway offered incentives in the early
years then phased them out as the industry became economic without assistance
(Ryggvik, 2015). At times, incentives have been phased back in to counteract
prevailing economic conditions such as the oil price crash in the 1980s, e.g., in
Norway (Lund, 2014) and the UK (Band, 1991). In some countries such as Indonesia,
hydrocarbon incentives are prevalent still today, however, it has been shown that these
do not achieve the goals they were intended to (economic growth, poverty reduction,
and energy security), and moreover, decrease the government’s revenue (Pradiptyo et
al, 2015). Metcalf (2018) demonstrated that in the USA, removing hydrocarbon
incentives would increase government revenue, though it would not mitigate energy
demand, which in turn would help the environment. The global O&G industry still
enjoys some subsidies in the form of uplifts for recovering or depreciating capital. At
55
the same time, it finds itself taxed more harshly than other industries in 49 countries
through SPT, including twelve countries whose SPT rate is 50% or greater (Wood
Mackenzie, 2022). The same source reveals that seven of those countries enact the
highest tax rate when price or revenue are above a certain level, but The Netherlands,
Denmark, and Norway have flat rates of SPT at 50%, 52%, and 56% respectively.
Renewable Energy Industry
Babcock (2013) concluded that subsidies can safely be removed in the USA when
the renewable fuel source can compete economically with hydrocarbon fuel sources.
Their study was into biofuel ethanol - the renewable energy source with the longest
history – and the first to consider removing subsidies. Burer & Wustenhagen heard in
2009 from their survey respondents that in general, investors expect renewable energy
subsidies to be removed in the future and that project economic base-cases are
calculated without subsidies as the timing of removal is unknown. Xiang et al (2021)
point to a second reason for the removal of subsidies – in China, renewable energy
increased thirty-fold from 2010 to 2018 and the government can simply no longer
afford the subsidies on this higher activity base.
As renewable energy sources become economic without subsidies, government
revenue could benefit from halting the incentive schemes (Xiang et al). This will be
an important milestone, especially in less well-off countries that wish to implement
renewable energy projects but cannot afford to subsidise the industry. As renewable
energy sources become more widespread, technological advances occur, and the costs
of installing capacity fall, subsidies and incentives may no longer be necessary
(Johnston et al, 2020, Lee & Xydis, 2022).
56
The post-subsidy age will benefit developing countries such as Vietnam (Zimmer
et al), which in 2014 was only able to offer a 1c/kWh subsidy on power from
renewables, barely improving their competitiveness compared to domestic
hydrocarbon supply.
Falling Costs of Offshore Wind
The World Bank (2019b) found that between 2000 and 2019, offshore wind
frequently cost US$60-200/MWh, three times that of onshore wind energy, but the
trends are downward (Figure 3). Eicke et al’s calculations confirmed that.
Figure 3: Levelised offshore wind tariffs to 2030
By 2018 (World Bank 2019b) China was consistently breaking the US$100/MWh
barrier for installed capacity and in Europe, auctions were revealing a cost below that
same barrier for capacity to be installed shortly thereafter. The IEA found (IEA, 2020)
that in 2019 onshore wind was the cheapest method of generating electricity from any
fuel source, and whilst OWE is more expensive, it is dropping faster as it is a newer
57
technology. IRENA (2019) points to several factors that will continue to drive costs
down – economies of scale as offshore wind penetrates the market, more competitive
supply chains, and technological improvements. They also observed that onshore
wind is already cheaper than new hydrocarbon-fuelled installations in many areas. In
their study about the removal of subsidies, Peng & Wu (2022) found that OWE cost
only two times as much as onshore in China in 2020. This agrees with the IEA 2020
view that onshore wind costs US$40-65/MWh and offshore US$75-110/MWh.
Auctions for capacity to generate OWE in 2023 in the UK now have a cost below
US$50/MWh (IEA, 2020), and in Germany and the Netherlands, zero-subsidy projects
have been bid (IRENA, 2019). Mathews et al find that the cost of even OWE is now
falling below hydrocarbon sources such as coal and gas, eliminating prior non-
competitiveness. NREL (2019) points to the 68% decrease in the cost of fixed bottom
OWE between 2010 and 2019 and the projected further decline of 42% by 2030 (from
US$89/MWh to US$51/MWh). Many countries are gaining an interest in offshore
wind due to the decrease in cost. For example, in the last decade Australia did not
consider OWE viable in its renewable energy mix but now finds that it will be cost-
competitive. Hence, they offered the above-mentioned lease in 2019 with plans for
more, producing up to 40 GW by 2037 (Rispler et al).
Mathews et al also see floating OWE, currently more expensive than fixed bottom
turbines, falling below US$60/MWh by 2030, and Casey cites areas offshore USA
costing US$50-75/MWh in 2023. Casey reports on the US Department of Energy’s
belief that due to technological advances, and she describes three, even floating
offshore wind can reach US$45/MWh by 2035.
58
Fixed bottom turbines can operate at water depths of up to 50m, often near the
shore. Some countries’ shoreline falls off more steeply and floating wind will be the
best option. This study will only consider fixed bottom turbines, but a future direction
would be to include floating wind farms.
There has been some discouraging news from the USA in 2023 about two
planned New Jersey OWFs being abandoned due to high inflation, rising interest
rates, and supply chain bottlenecks (Ørsted, 2023). However, no transition to a new
technology is ever smooth, and this researcher is going to continue to monitor the
situation and assume that one setback does not condemn the whole industry.
Rarely quantified, but nonetheless important, are the cost savings associated with
a shift to renewable energy (IRENA, 2019). The expenditure associated with the
health impacts of poor air quality and the clean-up and rebuilding after climate events
could be saved, decreasing the overall cost of power from renewable energy sources
versus hydrocarbons.
This cost decrease, and the associated end to the need for subsidies, will make
OWE available to countries who can neither afford to subsidise, nor develop sources
that cost more than the existing energy supply.
Offshore Wind Energy Subsidies
Denmark phased out subsidies paid for by the taxpayer (FITs) in 2000 (Fristrup)
though it appeared the move was premature as offshore wind generation capacity
installation stalled, and a new FIT-like instrument was introduced in 2008 (WWEA,
2018a) – and capacity installation resumed (IRENA, 2013a). Then in 2021, for the
first time, a Danish auction of seabed for an OWF resulted in cash inflow to the
59
government rather than the promise of cash flow from the Government to the
Contractor (Laido).
Similarly, the Netherlands introduced FITs in 2003 to then decrease them in 2005
when the government realised it could not afford them (WWEA, 2018b). The first
acreage to be leased without a subsidy was in 2018 (Laido) and the authors’
expectation at the time was that it would be the first operational OWF to involve a
payment to the Government rather than from it. Indeed, the winning bid by Oranje
Wind Power II C.V. included a one-off EUR50MM payment, and the farm will
receive no subsidies (Jetten, 2022). The farm, Hollandse Kust Zuid, was inaugurated
in late 2023 and is expected to commence operations in 2024 (Power Technology,
2023). Power sales are subject to a fifteen-year PPA.
Spain (WWEA, 2018c) had the same policy, offering FITs until 2013, at which
time the country switched to a tax on wind power, and new generation capacity
slowed. Despite this, Spain was still the fifth-largest combined onshore and offshore
wind producer in 2022 (IRENA, 2023). Conversely, Germany has been remarkably
successful – in 2021 the country was the third largest combined onshore and offshore
wind producer behind more populous China and the US. The government offered
stable, long-lived, and transparent policy and terms for several decades contributing to
the success (WWEA, 2018d). Although FITs halted in favour of auctions, the industry
survived, though small companies are likely to be driven out by this change (WWEA,
2018d). Jamasb & Sen (2022) and PWC (2018) point to zero-subsidy bids in Germany
as far back as 2017.
60
The UK has tried four policies since the 1990s – lacking stability and longevity –
but in 2021 was still sixth in the world in combined onshore and offshore generation,
and second in offshore alone (IRENA, 2023). From 2018 subsidies were phased out
and the WWEA predicted a fall in new licensing once the existing licences are
brought into production and older facilities are taken off-stream (WWEA, 2018e).
However, this trend was not evident judging by Westwood’s report that the 2022
Round 4 auction was the largest ever, or by late 2023 with the Government’s
announcement to offer sites for over 15 GW of floating wind in the Celtic Sea (The
Crown Estate, 2023). The 2021 seabed allocation auction ushered in a new era in the
UK with bids made including payments to the Government of EUR 250,000-
800,000 /km2 (Laido) during the wind farm development phase.
Groom (2023) reports that the large bonus amounts paid to the USA Government
in 2022 for offshore wind leases indicate the faith energy companies have in OWFs
which do not enjoy price support or FITs, though as previously discussed they do
qualify for production and investment tax credits.
In China, central government subsidies were removed at the end of 2021, and
Mathews et al opine that the policy change is an indication that the Government is
confident in the ability of the industry to be cost-competitive and achieve growth and
stability without assistance. Three provincial governments are not so confident and
have rolled out local subsidies which apply to wind farms coming online between
2022 to 2024 (Chen, 2022). These subsidies have less value the later the farm comes
online and will only run for the first 10 years of the farm’s life. China’s offshore wind
power targets have 2025 as the stated endpoint, so perhaps it is not a coincidence that
61
the subsidies apply to farms coming online by the end of the previous year. Chen
states that it is not the subsidies that are the main driver for OWE growth in China,
though the new construction activity has dropped to a more normally expected level
after the cessation of the national subsidy.
The Future
Subsidies will soon be behind us as wind farms under subsidy schemes make up
an ever-smaller proportion of total OWE. IRENA (2019) expects that offshore wind
will be subsidy-free by 2030 in many global markets. Jansen et al (2020) expect that
Europe will be subsidy-free by 2023 and judging by the earlier findings in the UK and
the Netherlands this goal has been achieved between 2021 and 2024. Kitzing (2023)
talks of the changes in approach required when offshore wind projects switch from
needing financial support to becoming net contributors to state finances. In her case
study of Denmark, she points to the policy shift recognising the need for subsides to
one of wanting to maximise income and profit for Danish society. Indeed, Bloomberg
Energy Voice (2022) reports that power from Triton Knoll, off the UK, is so much
cheaper than power from gas-fired plants that it is paying the excess between the cost
of generation and the sales price to the government. The article also points to Danish
Hornsea 2, which will soon be able to undercut Triton Knoll’s price by 22%. This
illustrates the shift from an industry requiring subsidisation to one that pays a negative
subsidy – or tax. An initial step in this regard may be a two-sided CfD (Jamasb & Sen)
which will attract a subsidy when the power sales price is below the cost to produce
but pay a tax when the price exceeds the cost.
62
However, CfDs are an adjustment to the existing contract type rather than a
radical change into a new era. This existing contract type has similarities to the
regressive fiscal regimes seen in O&G CAs where fees are fixed regardless of the
profitability of the project. Examples are auction bids (or lease bonuses), rentals (or
acreage-based fees), or rates applied to gross revenue (such as royalties or annual
per MW fees. These taxes on gross revenues can render a marginally economic
project sub-economic and halt that project. As Laido et al point out, this up-front
loading of costs can affect financing, competition, and commitment to projects. A
structure where the Government takes its cut from the profit rather than the revenue
would encourage marginal projects.
Any wind farms built with contract terms under discussion in this research would
not be operational until the mid-2030s, therefore zero-subsidy leasing is a good
assumption.
The Opportunity to Structure New Contract Terms
As Jamasb & Sen point out, there is an opportunity to consider the distribution of
revenues from OWE in the post-subsidy world. Perhaps an entirely different contract
type could offer an interesting way forward. Then it may be prudent to look to the
industry that has been producing energy offshore for decades – namely the O&G
industry. Snyder & Kaiser (2009) state that the regulatory system most applicable to
OWE is that of O&G due to the similarities between the industries – expensive
offshore installations that provide energy from offshore resources. As Stephanie
McLellan said of the overlap between offshore O&G and offshore wind, “It’s the same
63
industry, just using a different fuel” (Magill, 2019, paragraph 13). Why not also look
to the leasing system for best practices that could be applied to offshore wind?
Markwell et al (2014) posit that PSAs may be seen in the future in other (non-oil or
natural gas) types of hydrocarbons such as methane hydrates or coal bed methane, so
why not other forms of energy too? The argument may be made that oil and wind are
too different. Oil and gas can only be exploited once whereas wind is renewable – but
that fact need not drive the leasing mechanism. Oil is a transportable commodity
whereas wind-generated power must be used in situ or close by. But gas, which is
harder to load onto a carrier vessel and export, is also produced offshore and
transported by pipeline for use in regional markets. Additionally, wind-to-hydrogen as
a means to store and transport wind power is an emerging technology (He et al, 2022).
The hydrogen can be used at the installation or piped to shore in either former gas
pipelines or new-build pipelines. In this way, OWE could one day function like the
liquified natural gas (LNG) industry which converts the energy source (gas) to a liquid
to enable transportation to areas of demand. Spezakis & Xydis (2022) see offshore
wind-to-hydrogen as an economic method to transport power from the USA’s
Western Gulf of Mexico region to coastal populations as there are many unused gas
pipelines in the area. The authors tell us that since OWFs may be far offshore, the
cost of new submarine cabling will be greater than re-purposing gas pipelines.
Further, as hydrocarbon production decreases and more O&G infrastructure is
abandoned, more pipeline infrastructure becomes available. The differences in storage
and transportability of oil, gas, and wind do not dictate the leasing mechanism.
64
A second argument for the differences between OWE and O&G is that
hydrocarbons often provide a large portion of foreign income for a government
(Sunley) whereas power, if used locally, will not. Again, this need not drive the
leasing mechanism. The differences in the energy types do not constitute a reason not
to study the transferability of PSA best practices to OWE.
It is true that mathematically speaking, the same financial outcome can be
achieved by using a CA or a PSA – depending on how the terms and rates are
designed (Sunley) – so a hydrocarbon-style CA could equally be applied to offshore
wind. The result would be similar to existing offshore wind leasing in developed
countries. However, the CA may replicate the PSA for one specific project – but if the
project’s parameters change, the outcome may be very different. The CA, being
regressive, will harm marginal projects and dissatisfy Governments in highly
profitable cases. Additionally, Governments would be missing out on the non-
financial benefits detailed elsewhere in this paper that can be enjoyed when using
PSAs.
Olleik et al (2021) studied an innovative suggestion for diverting a portion of the
profit oil or gas in a hydrocarbon PSA to investments in renewable energy in
Lebanon. This provides a linkage between O&G company strategies to invest in
renewables and a developing country’s need to fund such projects. This was the first
suggestion in the literature that PSAs could be connected to the funding of renewable
energy projects but does not apply the PSA to leasing for an OWF. Hassan et al talk
about future PSA evolution as environmental policy develops, but like Olleik et al, do
not go as far as suggesting a PSA could be applied to more climate-friendly energy
sources.
65
Going further than those studies, and to the best of this researcher’s knowledge,
this current study is the first to explore the use of PSA-like terms for an entire
renewable project without a hydrocarbon element.
It should be noted that the use of PSAs does not preclude the current use of
auctions as the method to allocate seabed; the PSA forms the lease contract. Jansen et
al (2022) expect by 2030 that 97% of all seabed sites awarded will be by auction. The
PSA would govern the terms of the contract area for the lifetime of the project. Those
terms could either be directly negotiated with the Government or could be biddable in
an auction to foster competition. Both approaches are seen in the hydrocarbon
industry – 34 countries use PSAs in conjunction with licence rounds (bids), 21 directly
negotiate, and 26 use both (Wood Mackenzie). As discussed before, the use of PSAs
does not preclude the use of PPAs for the offtake and sale of power. In Germany and
the Netherlands, both seabed access and offtake are bid in the same auctions whereas
in the UK and USA, they are handled separately (Bloomberg NEF, 2022). Either way,
using a PPA to bring certainty to the revenue achieved from the project would work in
conjunction with a PSA governing the relationship between Contractor and
Government. A PSA-like contract, being the leasing mechanism, could also dovetail
with RPS or other renewable targets that a government might set – the targets set the
ambition, and the leasing contract enables its fulfilment.
Fair Sharing of Profit
Given the rapid drop in the cost to produce power from offshore wind, long-
term fixed-price contracts seem biased toward the Contractor. As profitability
increases, even over the life of a given installation, the resource owner or
Government may be
66
forgoing revenue from its natural resource (Snyder & Kaiser). The authors discuss two
forms of lease fees which are payable from gross revenue (royalties) or paid
regardless of revenue status (rentals) and their regressive nature. If these lease fees are
set at a low level to encourage investment, the resource owner misses out on the
upside in the case of a highly profitable project. PSA-like contract terms, which share
revenue at multiple stages of cash flow, can be structured to be highly progressive and
avoid these pitfalls. The Royalty, calculated on gross revenue, ensures that the
Government receives at least a minimum payment, and the Profit Split ensures that the
upside is enjoyed by both Contractor and Government (Sunley). Corporate Income
Taxes may not provide the same degree of profit-sharing for the Government if the
Contractor company has other losses to offset successful wind projects.
Fair Recovery of Cost
With its cost recovery mechanism, the PSA provides better assurance to the
Contractor that its investment will be recouped. Under a CA-like system, no allocation
is made from revenue to repay the Contractor for capital and operating expenditures.
Under PSA-like terms, the Contractor recovers costs before the remaining revenue is
split according to the Profit Split ratio. Recovery of cost is an attractive feature for an
investor willing to spend billions of dollars building an oil field or wind farm. Cost
recovery is clearly not a necessary condition, given that OWFs are being built without
this assurance, but this research aims to uncover whether PSA-like terms might be
superior to a CA-like leasing system in offering this feature.
An area of contention in O&G leasing is who pays for site identification
performed prior to an auction or bid round. This could involve industry-sponsored or
67
proprietary company seismic studies over an area of seabed to ascertain if it is
attractive for leasing. Under the CA system, there is no mechanism to recover those
costs, at best they can be considered tax deductions. Under a PSA, the expenditure
made before the contract was signed on the contract area can be considered allowable
for cost recovery under the PSA when eventually signed (Nichols, 2010). Indeed, they
are often recovered before any current operating or capital expenditure. Do et al
discuss this issue in reference to OWE, positing that the industry wants to identify
suitable sites for OWFs – in fact they prefer to undertake the surveys than let the
Government carry them out – but they do desire a mechanism to later recover those
costs. As in O&G, this would be more easily accomplished via contracts, like a PSA,
than through concessionary systems.
Encouragement of Marginal Projects
If lease fees are high, marginal projects will not be developed and both
Contractor and Government get no revenue - and the local area will have to source
power by another route. A more flexible contract type, like the PSA, which varies the
rates of revenue-sharing based on the profitability of the project, may be appropriate
for OWE. Its progressive nature would provide the opportunity for marginal projects
to be developed and for the Government to take large revenues from highly successful
projects. This has been recognised by Firestone et al in their analysis of the USA’s
offshore wind leasing regime though in the eight years since the authors made the
observation, the USA’s regime has not changed.
68
Community Benefits
Community benefits in existing offshore wind leasing agreements in Europe and
the USA were analysed previously in this paper. A PSA-like contract, including
O&G- like provisions for local development, would take these community benefits
further, sealing them into the contract for the life of the wind farm. Benefits could be
specified, unlike the financial amounts seen in the UK with no explicit project
attached. Developing countries could negotiate terms for education, training,
infrastructure building, and local content (jobs and use of local manufacturing
capacity). Infrastructure could be defined as industry- and supply chain-related, such
as port improvements; schools or universities for education and training; and civil
projects such as roads. Given the smaller profit margins of power generation projects
compared to successful O&G projects, it is likely that the scope of community
benefits per contract will be smaller than for O&G, but nonetheless desirable to the
Government offering the contract.
Knowledge and Expertise Transfer
Developing countries with natural resources, but which lack the capital and
human resources to develop those assets, favour PSAs (Markwell) as a way to inject
finance and expertise into the projects. This expertise transfer comes through the
establishment of the NOC and its participation in the projects. For OWE, a NEC could
be set up and participate in the PSAs with the international Contractors. Once there
has been an expertise transfer, the domestic industry can develop smaller projects that
would not attract the interest of larger international energy companies (Markwell).
The domestic market can be satisfied without reliance on outsiders. Almost a decade
ago,
69
IRENA (2013b) found that a market driver for wind energy, and a motivator for
countries to encourage the industry, is creating local economic value through jobs and
manufacturing. In 2019, the same organisation pointed out that the right education and
training are crucial to the establishment of local supply chains to facilitate offshore
wind projects. Similarly, they state that policy must encourage the development of a
workforce. The use of NECs and local content clauses in PSAs could support this
goal. In fact, this behaviour can be seen in the USA, for example at Vineyard Wind in
Massachusetts, where the developer committed US$15 million of funding for
education programmes and apprenticeships to build a wind energy workforce (Tyler et
al, 2022). This was an important factor in gaining local acceptance of the planned
installation. This kind of local benefit is commonplace in a PSA and would not have
to be tackled as a separate initiative. Study participants from the local community
around the proposed Kitty Hawk Wind Lease (offshore North Carolina, USA)
expressed an interest in discounted electricity for residents as a way to increase
acceptance of the development of a wind farm (Tyler et al). This is similar to the
DMO often seen in PSAs, where hydrocarbons are sold to the host country at a
discount to market prices.
Risk Sharing
It is true that the choice of fiscal regime in the hydrocarbon industry is driven in
part by risk and reward sharing – there are immense risks and costs in O&G
exploration, which concerns IOCs (Kaiser & Pulsipher, 2005a, Tordo et al, 2010,
Pongsiri). A company can spend hundreds of millions of dollars on a leased area: on
leasing, seismic studies, and drilling, and there is only a 10-30% chance this expense
will ever be recovered (Brez-Rouzaut, 2022). The cost of exploring for oil or gas – and
70
finding one drop of hydrocarbon - not for developing the field or producing it – can
run from US$200MM (million) to US$500MM for a 100 MM barrel field (Brez-
Rouzaut). By contrast, a US$4MM to US$10MM feasibility study can determine the
wind potential which drives the design and cost of an offshore US wind farm
(Finmodelslab, 2023 and Appendix 1) Despite this mismatch in risk, the PSA, with its
multiple revenue streams to the government and non-financial benefits including
local development and equity participation, offers an interesting alternative to the
leasing mechanism seen in developed countries. Further, as discussed earlier, with
the use of long-term PPAs, revenue can be made less uncertain.
This research is the first to explore the reasons why governments of developing
countries with untapped OWE resources could find using PSA-like contracts
advantageous. The governments could develop the new industry since costs are
falling, OWE is becoming cheaper than hydrocarbons, and subsidies are ending. This
research also demonstrates under what high-level conditions and contract terms OWFs
can be financially successful for both Contractors and Governments using PSA-like
contract terms, and what should be considered when negotiating.

CHAPTER 3
METHODOLOGY
Mixed Methods
This mixed method research follows a convergent design utilising two
interleaving exploratory phases. Since the 1990s, the importance of combining
qualitative and quantitative methods in social research has been recognised (Allen-
Meares & Lane, 1990). Mixed methods can aid in furthering research in business
studies because the type of data and analysis are different in the two phases and can
provide a broader or deeper understanding than quantitative or qualitative research
alone (Molina-Azorin, 2016; Kelle & Erzberger, 2004). In this research, neither the
quantitative nor qualitative approach alone would have been adequate to explore the
research questions fully.
In this concurrent triangulation approach (Cresswell & Cresswell, 2017), also
known as a convergent parallel approach, the two databases generated are not
comparable during analysis, but the findings are drawn together in the discussion
phase of the research. The strength of the approach is the resultant triangulation of the
conclusions, coupled with the time efficiency of parallel data collection. This approach
is clearly applicable to this research problem/opportunity. The quantitative and
qualitative phases were independent, answering two important but separate questions.
The quantitative phase examined whether the PSA-like fiscal terms work
financially/mathematically for OWE and provide positive returns to entice both
contracting parties to enter into the agreement. The qualitative phase investigated
whether all the terms, fiscal and non-fiscal, can be applied to OWE and what benefits
might accrue to the contracting parties besides a positive NPV. The knowledge
72
uncovered by the two phases was amalgamated into one conclusion on the applicability
of PSA-like terms for OWE. Arguments could have been made for a phased approach
in either combination. Finalising the quantitative research first could have provided
interesting information for the qualitative stage participants to discuss or conversely it
could have biased their opinions. Finalising the qualitative research first could have
provided the impetus for moving forward with the quantitative research – without
industry experts who see benefits to using PSA-like terms for OWE, the financial
outcome would have been a moot point. The drive for efficiency dictated that the
phases were pursued simultaneously; when there was a waiting period for one (e.g.,
waiting for Institutional Review Board (IRB) or scheduled interviews), the other
research went ahead, and when there was a deadline (such as an interview date), the
focus switched in order to conduct and transcribe the interview, and perform the first
level coding while the information was fresh in the researcher’s mind. This approach
had the advantage that the conclusions from one phase could not bias the other; both
were truly exploratory.
Researcher Credentials
The researcher has 30 years’ experience in the hydrocarbon industry and
although she has no direct career involvement in the renewable energy sector, she is
increasingly compelled to contribute to the urgent transition from the former to the
latter. She modelled PSA fiscal terms in Microsoft (MS) Excel and ran project
financial analyses for decision-making from 1998 to 2006 at four different O&G
companies: a super-major, two international independents, and a consultancy. The
researcher’s long experience with modelling contract terms and MS Excel will provide
73
a good foundation
74
for high-grade quantitative analysis. In the qualitative study, the researcher is a peer of
the participants and is skilled and knowledgeable about PSAs and their application in
O&G. From 2007 she was in management, corporate strategy, negotiations, and
mergers and acquisitions for two NOCs, which involved a detailed understanding of
contracts and their terms’ effects on the parties’ financial and non-financial positions.
During this management period, she gained practical skills relevant to research such as
interviewing and parsing themes from conversations to convert into corporate strategy.
The researcher’s long experience will assist in understanding the concepts
uncovered in the interviews. The researcher’s relatively recent interest in the wider
application of the terms to renewable energy will not be an impediment to
understanding as the participants are experts in O&G, not renewable energy.
Theoretical Foundations and Researcher Approach
The application of PSA-like terms to OWE has never been studied before (at least
nothing has been published). Thus, there is no established theoretical lens through
which to investigate. The research is exploratory in that the use of PSA-like terms for
OWE is a new concept. Thus, the epistemological approach to the research is
grounded theory. Whilst theory creation as such is not sought, if the quantitative
hypotheses are accepted and the qualitative research yields a practical application,
an existing concept (PSA terms) will be applied in a new context (OWE), which is
one use of grounded theory (Kelle, 2014). The research is not seeking to study or
explain an existing phenomenon but to introduce a new idea which can play a small
part in the transition from fossil
75
fuels. In the interviews, the initial discussion under RQ4 will serve as a springboard
for the discussion of RQ5, the new concept.
The researcher is a post-positivist in that she believes in and seeks explanations,
but also a pragmatist in believing there can be more than one interpretation and
explanation depending on the perspective of the viewer. Whilst post-positivism relies
on deduction, pragmatism embraces induction. Induction serves well in this
exploratory research. The researcher believes that human activity affects our world
for better or for worse; regardless of whether climate change was/is human-made,
constructive changes to our planet can be made in the future by humankind, by
changing our behaviour. The researcher believes an answer to the hypotheses can be
discovered empirically and although the participants may have differing opinions, the
quantitative simulation will reveal truths about the use of PSA-like terms for OWE.
Data Collection Schedule
This research study advanced through the process as required within the URI
dissertation framework. Namely, a dissertation committee was formulated by Spring
2023 – the committee heard/read the comprehensive examination. By late June of that
year, IRB approval was received for research on the American interviewees. By late
August the IRB approved research on the Norwegian interviewee.
The quantitative portion of this mixed method research commenced in June 2023
utilising data generated by simulation and therefore not requiring IRB approval. The
cash flow model and simulator had been built in 2022 and the selection of input
distributions was finalised in June 2023. The model could then be used at any time to
76
generate data. The data for the T-tests and multiple regression was collected in August
of the same year. The data for the scenario analysis was collected in September and
October and the qualitative interviews were conducted during July, August, and
September.
Data for the two types of research proceeded simultaneously. As mentioned
before, when there was a natural pause in one data collection effort (e.g., whilst
waiting for the second IRB approval), the other data collection could become the
focus.
Quantitative Study
Meta-modelling to Analyse Fiscal Regime Feasibility
Traditionally the O&G industry has used deterministic cash flow modelling
techniques to evaluate assets and projects, with decision trees and Swanson’s means
employed to assess risk (Researcher’s experience, 1992-2021). Papers are written,
entire conferences happen, e.g., Mian (2020), SPE HEES (1991 to 2016), to try and
shift the industry towards more sophisticated stochastic methods, yet companies’
formal decision-making processes remain simple, and/or not fit for purpose (Mian).
Even where stochastic analysis is seen, with input variables represented by
distributions, the use of formal statistical methods such as multiple regression is not
included (Researcher’s experience).
Kaiser & Pulsipher (hereinafter known as KP) introduced the concept of meta-
modelling to the O&G industry in their series of four papers from 2004 to 2005
(2004a; 2004b; 2005a; 2005b) and applied it to studies in the USA’s Gulf of Mexico
region (2004b) and Angola (2005b). The methodology has further been applied to
77
assets in China (Hao & Kaiser, 2010) and Nigeria (Adenikinju & Oderinde, 2009;
Ojaraida et al, 2018). As KP point out (2004a) there are many uncertainties involved
in evaluating an oil or gas field prior to an investment decision. These include
geologic risk, and production, price, cost, investment, technological, and strategic
uncertainties. A deterministic cash flow model, in which one fixed value is selected
for each input data point, cannot encompass these uncertainties. Analysis in the O&G
industry typically centres around a base-case outcome, compared to several “high”
and “low” scenarios in which one or more variables are set to higher or lower values
(KP 2004a). The meta-modelling approach goes beyond deterministic cash flow
analysis, using the model together with simulation to generate meta-data. This meta-
data undergoes multiple regression analysis to understand the interaction of the
variables (KP, 2005a). In their application of meta-modelling to the typical Angolan
PSA (Model I in their paper), KP (2005b) select seven parameters to be represented
by uniform distributions in the simulation: Production, Royalty Rate, CRC, Uplift
Rate (applied to capital costs), Tax Rate, Contractor Discount Rate and Government
Discount Rate. The output variables from the cash flow model are Contractor Take,
Net Present Value (NPV), and Internal Rate of Return (IRR). The regression
equations for each output variable give insight into the strength of the effect of a
change in each input parameter. In turn, this can inform the Government in setting an
appropriate fiscal policy for the hydrocarbon industry and can guide both Government
and Contractor in agreeing acceptable negotiable terms in the PSA.
This quantitative research used KP’s method with some changes to the input and
output variables. In KP’s three papers on PSAs (2005a, 2005b, and 2006), the myriad
78
fiscal terms to be found in the contract were simplified to four key predictor variables
which are considered in this research: Royalty, Cost Recovery Ceiling, Profit Oil
Split, and Tax. The fact that these four are the key components of a PSA is confirmed
by Tordo et al and Adenikinju & Oderinde. In addition, Uplift, a commonly used
fiscal term to encourage investors to new geographic, geologic, or technological areas
will be included, as KP did in their analysis of the Girassol field under an Angolan
PSA (2005b), for a total of five contract-term independent variables (IV). Profit Oil
Split is renamed Contractor Profit Split (CPS) for consistency with the OWE work to
follow. As offshore wind is a new technology and building OWFs under PSA terms
means bringing the farms to new geographies, an Uplift is considered an appropriate
inducement to investors. This research then advances the modelling technique by
applying it to an OWE project rather than the oil fields on which it has been used to
date.
Future studies could expand this predictor/IV set to include a further list of fiscal
terms that have a lesser effect on the project economic results.
Similar to KP’s method, Production (renamed Generation for the OWE model),
Price, and Contractor Discount Rate were non-contract term inputs/IVs represented by
distributions. Additionally, Government Discount Rate was included as the ninth and
final IV, as it is necessary for the calculation of Government NPV. Details of all the
distributions of these variables are given in the following sections.
This research goes beyond KP’s in a second way by looking at the contract terms
from the perspective of both contracting parties. Government NPV is included as an
output/dependent variable (DV), as it is the Government who would offer the lease
79
under these contract terms, so a positive financial outcome is critical for them.
Contractor NPV is the second DV, as a positive NPV is also critical for them, as the
investor. Future studies could expand this DV set to include other economic measures
such as Contractor IRR, Contractor Take (both of which KP studied) and Government
Take. The variable names, codes, acronyms, and types can be found in Table 1.

The cash flow model was built using MS Excel and screen shots of the tables and
worksheets can be found in Appendix 3.
The parameters for the distributions representing the stochastic variables are
detailed in the next sections of this paper. These are seen in action in Figure 27
(Appendix 3) on the right-hand side and feed the input variable cells in the same
figure
80
on the left-hand side. The output variables are also captured on the bottom right of the
same figure.
A snapshot of the cash flow model can be seen in Appendix 3, Figure 28, and
Figure 29 and Figure 30 show the cost input deck and the depreciation calculation.
A macro can be run to calculate the model as many times as desired, with
different values of the stochastic input variables selected by Excel for each trial. The
cash flow is recalculated, and the new output variables are displayed. For each trial,
the macro captures the input and output variable values as shown in the trial collection
data worksheet seen in Appendix 3, Figure 31. This is the raw data that can be
exported to run statistical tests or examined in scenario analysis. For each trial, this
worksheet collects the two dependent/output variables, Contractor and Government
NPV, the five contract-term IVs (Royalty, CRC, CPS, Uplift Rate, and Income Tax
Rate) and the four non-contract term IVs (Average Price and Average Generation
over the life of the project, and Contractor and Government Discount Rates).
Please note that the convention of M signifying thousands and MM signifying
millions has been used where applicable.
Calibration of Cash Flow
Model
The cash flow model was first calibrated by replicating KP’s analysis of a PSA
(KP, 2005a), applied to an oil field. The model file name is Economic Model - PSA for
OWE Kaiser Oil Inputs. The IV distributions in Table 2 were lifted from KP’s paper
(Model I) and input into this research’s model. The other model inputs (oil production
profile and cost profiles) can be found in Appendix 4.
81
Independent Variable Distribution Type Lower Bound Upper Bound
Price (Oil) Uniform $10 $30
Royalty Rate Uniform 10% 30%
CRC Uniform 10% 75%
CPS Uniform 10% 75%
Tax Rate Uniform 20% 40%
Contractor Discount Rate Uniform 15% 40%
Table 2: KP 2005a independent variables
The values for the distribution in KP’s research differ from the values used later
in this OWE research as the economic conditions were different in the O&G industry
two decades ago. However, for the purposes of calibration, they can be replicated. KP
had three DVs, NPV, IRR and Contractor Take, only one of which coincides with the
DVs in this research (Contractor NPV and Government NPV). This calibration
therefore uses Contractor NPV as the DV.
The model for this research will not match KP’s exactly. It is not known what
country’s PSA contract structure KP used as the framework for their model, nor what
accounting and tax laws they modelled, nor whether they included more minor PSA
terms such as bonuses, DMOs, training budgets, and others. For the sake of
parsimony, this research does not include these. However, the direction of each
multiple regression coefficient was expected to be the same and the magnitude of the
coefficients are expected to be similar relative to one another. The model was run
10,000 times and the data was collected to run a multiple regression. KP only ran their
model for 500 trials.
The regression model used matches KP’s for Contractor NPV, namely:
82
Contractor NPV = ß1 + ß2 * RoyaltyRate + ß3 *CostRecoveryCeiling +
ß4 * ContractorProfitShare + ß5 * TaxRate + ß6 * ContractorDiscountRate + ß7 *
AveragePrice.

Table 3: Expectation of regression coefficients and the values KP found
The following tests were satisfied:
Ratio of cases to independent variables: there are six IVs in each regression and 10,000
cases so that requirement is well satisfied.
Outliers: The DV was plotted against each of the six IVs (Appendix 5), and none
revealed outliers, so no data was removed.
Multicollinearity and singularity: the average Variance Inflation Factor was calculated
in Stata from the R2s. The result for Contractor NPV was 1.0000, which is less than
10, so multicollinearity is not an issue.
83
Normality: the plot of residuals for the DV, Contractor NPV, was generated in Excel
and the data were normally distributed. They can be seen in Appendix 6.
Heteroscedasticity & Linearity: Residuals plots for all IVs look linear. CPS shows a
hint of heteroscedasticity and Contractor Discount Rate shows a little more, but
neither are to a concerning degree, so the data is left as is. Plots can be seen in
Appendix 7.
No cases had missing data, n = 10,000. Table 4 displays the results for regressing
Contractor NPV on the six independent variables from the file Dataset1. The
regression was statistically significant, with R-squared = 0.83, F (6, 9993) = 8330, p <
0.001.
84
Table 4: Regression of Contractor NPV on six IVs
85
All six IVs had a significant effect on the DV with this research’s model, whereas
KP found that Royalty did not have a significant effect on Contractor NPV. They
found it did have a significant effect on the other DVs they measured, namely IRR and
Contractor Take, and the authors did not comment on this apparent discrepancy in
their discussion.
R2s were similar at 83% and 87% and the coefficients had the same direction and
relative magnitude in all cases except Royalty (Table 5). For example, both sets of
research found Contractor Discount Rate and CPS to have the most impact on
Contractor NPV. A larger sample size than 500 in KP’s research may have yielded
easier-to-explain results for Royalty Rate.

Number of Trials
The calibration model sample size was 10,000 trials and the exercise was run ten
times to confirm that the sample size was sufficient. Table 30 in Appendix 8 shows the
constant and coefficients in each of the ten runs, from files Dataset1 through
Dataset10, and the means, standard deviations, and coefficients of variation.
86
The coefficient of variation (standard deviation/mean) is below 5% for all IVs in-
dicating stability of the outputs (DVs). The coefficient of variation for the constant is
higher at 14.4% indicating stability but of a lesser degree. A sample size of 10,000 tri-
als is sufficient for the research.
Parameters for Fiscal Contract Terms
The initial distributions for the variables Royalty, CRC, CPS, and Income Tax
Rate are based on current global PSA contracts from the confidential database
provided for this research by Wood Mackenzie (2022). Uplift tends to differ from
contract to contract and is not available by country in the database. Uplift will
therefore be modelled as KP did in their paper studying the Girassol field (2005b),
governed by a contract which includes uplift. The distribution is a uniform
distribution bounded by 30% and 50%.
The distribution for Royalty rates was identified from the mean of the mid-point
of each country’s oil and gas royalties, not including countries that do not have
Royalty in their fiscal regime. For example, [country name redacted1] oil Royalty
varies between 10% and 15% depending on the return of the project. The gas Royalty
also varies between the same points. The mean point for each fluid is therefore 12.5%
and the mean of the mid-points is 12.5%. [Country name redacted1] was removed as
an outlier having a Royalty mid-point of 50.00% compared to the next highest mid-
point of 20.00% (Figure 4).

The distribution of the means of the mid-points over the remaining 58 countries
with PSAs with Royalties is shown in Figure 5. The mean is 8.50% and the mean
standard deviation of the two sets (oil and gas) is 3.97%. The range is 0% to 20%.

The distribution was subjected to the Kolmogorov-Smirnov test to check for
normality. The null hypothesis was that the data are normally distributed. N = 117 so
for an alpha of 0.05, the critical value is 0.1257. The calculated maximum was 0.0956
so the null hypothesis cannot be rejected, and the data are normally distributed. The
mean was not weighted by the number of contracts as that number is unknown – and
these input variables are merely starting points which will have a later adjustment to
optimise for an OWE regime. The value for the IV Royalty is bounded by 0% at the
low end of the scale and 100% at the high end, as neither negative Royalty, nor
Royalty above 100% have real-world meaning.
CRC, CPS, and Corporate Income Tax were calculated in the same way. No
outliers were found (Figure 6).
89

types
The mean of the mid-points of the O&G CRCs is 66.94% and the standard
deviation is 15.70%. The range is 35% to 100%. The distribution is shown in Figure
7.
90
Figure 7: Histogram of CRC rate mid-points (82 countries; 161 data points) illustrating a lack of
normality
The distribution was subjected to the Kolmogorov-Smirnov test to check for
normality. The null hypothesis was that the data are normally distributed. N = 162 so
for an alpha of 0.05, the critical value is 0.1069. The calculated maximum was 0.1121
so the null hypothesis is rejected, and the data are not normally distributed. This is in
part due to the large number of countries that have the CRC set at 100%. 100%
cannot be excluded in this analysis as it is a common value for the contract term. The
distribution for CRC for this research is therefore represented by a uniform
distribution bounded by 30% and 100%, the upper and lower bounds of the Wood
Mackenzie data.
The mean of the mid-points of the oil and gas CPSs is 50.85% (to the Contractor;
profit split to the Government is therefore 49.15%) and the standard deviation is
15.33%. The range is 17.5% to 95%. The distribution is shown in Figure 8.

Figure 8: Histogram of CPS Rate mid-points (82 countries; 161 data points) illustrating normality

for an alpha of 0.05, the critical value is 0.1257. The calculated maximum was 0.0749
so the null hypothesis cannot be rejected, and the data are normally distributed. The
value for the IV CPS is bounded by 0% at the low end of the scale and 100% at the
high end, as neither negative CPS nor CPS above 100% have real-world meaning.
The mean of the corporate income tax rates is 31.32% and the standard deviation
is 10.72%. The range is 12.5% to 65%. The distribution is shown in Figure 9.
92
Figure 9: Histogram of Income Tax Rate mid-points (80 countries; 80 data points) illustrating normality
The distribution was subjected to the Kolmogorov-Smirnov test to check for

for an alpha of 0.05, the critical value is 0.1521. The calculated maximum was 0.0996
so the null hypothesis cannot be rejected, and the data are normally distributed. The
value for the IV Income Tax Rate is bounded by 0% at the low end of the scale and
100% at the high end, as a negative Income Tax Rate or an Income Tax Rate above
100% has no real-world meaning.
Wind Generation Data
The latest advance in offshore wind turbine size came in early 2023 which saw
the construction of the first farm of 16 MW turbines in China (Lewis, 2023a). An
even larger 18 MW turbine was being prototyped in the same year and 2024 saw the
design of the first 20 MW turbine (Koragappa & Verdin, 2024). Slightly smaller 15
MW turbines first came online in 2022 and are to be installed offshore New York and
93
New
94
Jersey in the mid-2020s (Lewis, 2023b), so 15 MW turbines will be used for the
quantitative portion of this research.
Similarly, the average size of a large (over 500 MW) fixed bottom OWF has been
increasing year on year. Latterly in the last decade, from 2017 to 2019, such farms had
an average capacity of 703MW, as can be seen in Table 6. However, farms over 500
MW built in this decade are bigger, averaging 848 MW, also in Table 6.

95
Planned wind farms that will follow from the 2022 California lease round, as
reported by Ayoub (2023) will be of an even larger 1 GW size, which will be common
by 2030. India (Times of India) and Brazil (Buljan, 2023) are leasing for future 1 GW
and 2-3 GW OWFs respectively. Should a developing country wish to design and
implement new contract terms, offer seabed for lease, and see wind farms built, it
would take time, so this research assumes that the farms under PSA come online in
eleven years, in 2035. Since the research anticipates operational farms in 2035, a 1
GW farm will be modelled. Given Australia’s ambition to have four regions, each
with 10 GW capacity, online by 2037, from a starting point of only one area leased in
2023, a 1 GW farm in 2035 in a country with no leases today does not seem overly
optimistic.
A 1 GW farm would require sixty-seven 15 MW turbines and would produce
5360 GWh/yr of power (calculated from Lewis, 2023b). This implies a capacity factor
(average power generated divided by peak capacity) of 61%. A 1 GW farm could
produce 1 x 24 x 365 GWh = 8760 GWh annually running at peak capacity; 61% of
that is 5360 GWh. NREL (2022a; can also be seen in Appendix 9) expects capacity
factors to average 50% (range of 46% to 54%) in 2035 for the best potential sites
(over 8m/s wind strength). Combining these data, since both sources are used in this
research, gives a capacity factor range of 46% to 61%.
At the early stages of evaluating offshore wind projects the industry normally
assumes a fixed generation profile for the life of the wind farm. It is not until the
construction or operation phase, when site-specific lidar data are collected, that the
profile would vary for the purposes of cash flow modelling (name withheld, 2023).
96
The profile for this research will therefore be homogenous year-on-year and will
follow a uniform distribution based on a 46% to 61% capacity factor.
Power Price Data
The wholesale power price is calculated from the Statista data set (Global Power
Prices, 2023), shown in Appendix 10. Only countries which have offshore wind
currently or have leased for offshore wind are included in the price distribution, as the
price for power in countries which do not have, or may never have OWE, are not
deemed relevant. These countries may have no shoreline (Rwanda) or may have such
large oil and gas reserves that power generation is cheap and heavily subsidised (UAE,
Russia, Saudi Arabia, Qatar, and Iran). In these latter countries, OWE would never be
competitive therefore contract terms are irrelevant, and they would not be an audience
for this research. Some countries may be future candidates for OWE (e.g., Italy,
Singapore, South Africa, Mexico, India, and Turkey), depending on many factors
including future power price. If the governments begin to offer leases the price from
Statista could be included in an update of this research.
The retail power price in the remaining countries is then converted to a wholesale
price based on the assumption that 56% of the retail price is the wholesale price (EIA,
2023). The mean of the resultant distribution is US$141.86/MWh and the standard
deviation is US$69.147/MWh. The range is US$44.8/MWh to US$268.8/MWh. The
distribution was subjected to the Kolmogorov-Smirnov test to check for normality.
The null hypothesis was that the data are normally distributed. N = 12 so for an alpha
of 0.05, the critical value is 0.1083. The calculated maximum was 0.9605 so the null
hypothesis is rejected, and the data are not normally distributed. The distribution for
97
power price for this research is therefore represented by a uniform distribution
bounded by US$44.8/MWh and US$268.8/MWh. Since the levelised cost of energy
from offshore wind is now dropping below US$50/MWh (IEA, 2020), this lower
bound seems realistic.
Wind Farm Cost Data
The cost inputs are taken from a dataset provided by NREL (2022a), hereinafter
referred to as ATB (annual technology baseline). Explanations and definitions of the
dataset can be found at NREL (2022b). The data used in this analysis can be found in
Appendix 9.
Construction Capital Expenditure
The costs used are 2032 forecasts for the construction of class 1 to 5 farms (where
class refers to the wind speed). Class 6 and 7 wind speeds were not included as they
represent lower wind speeds and projects less likely to be economic. It seems
reasonable to expect the first wind farms in new countries to be in the best areas. The
forecasts for 2032 are used as the contracts would be signed for construction
commencement in 2032 in order that the OWF be operational in 2035. As the contract
price would be fixed in 2032 it would be unrealistic to expect the 2033 and 2034
construction costs to fall in line with the ATB dataset forecasts.
Each class contains three cost estimates: advanced, moderate, and conservative.
This refers, among other things, to the turbine rating - the moderate, or middle, case
matches the 15 GW turbine assumption in this research, therefore the moderate case is
used in the analysis. The other cases could be used when analysing the robustness of
the project economics to changes in cost. The costs do not exhibit any clear
98
distribution, so a uniform distribution is used in this research where the upper bound
matches the class 1 cost estimate and the lower bound is the class 5 cost estimate.
The split of the total cost over the three-year construction time is 40:40:20 per the
ATB dataset and Appendix 9. The distribution is sampled once for a total capital cost
in 2032 and that total is split by the aforementioned ratio to divide it between the three
construction years 2032, 2033, and 2034.
Pre-construction Capital Expenditure
It is likely that funds are spent on management, studies, front-end engineering
design, and other tasks prior to construction. These amounts are not included in the
ATB dataset and are not reflected in this research. This approach is acceptable as they
would be small amounts compared to the funds required for construction, so they
would not influence the NPV greatly.
Grid Connection Costs
These are included in ATB estimate.
Financing
These are included in ATB estimate.
Operating and Maintenance Expense
The operating and maintenance (O&M) costs are also taken from the ATB
dataset. Again, the class 1 through 5 estimates are used, in the moderate case, to
create a uniform distribution from which to sample. ATB provides forecasts annually
through 2050, which are used in the analysis. The costs for the period 2051 to 2064
are not provided by ATB, so the 2050 costs are used. Arguments could be made for
increasing the cost by an inflationary measure - or for decreasing the cost due to the
99
learning curve, and those factors may cancel each other out, so no adjustments are
made. Since the O&M cost is only equivalent to 3% of the upfront capex amount and
is discounted by fifteen or more years from 2051 to 2064, it has little effect on the
outcome.
No decommissioning cost is included in the simulation as a large OWF has not
been decommissioned yet. Decommissioning of OWFs off the USA was modelled
over a decade ago by Kaiser & Snyder (2023) and the removal and site clearance
would be expected to cost US$115M to US$135M per MW. This implies an average
cost of US$125MM to decommission a 1GW OWF. However, given the fall in OWE
costs, estimates formulated a decade ago are potentially overstated. At that time,
OWFs were sized in MW, not GW, and economies of scale would apply. By 2019, the
largest OWF to be decommissioned was 10.5 MW, off Sweden (Adedipe & Shafiee,
2021). Finally, the cost will be discounted so heavily over thirty years that it will have
a minimal effect on the results, so it is omitted from the analysis.
The life of assets has been fixed for simplicity at 30 years (Sun et al, 2019).
Other Input Data
Discount Rates
Contractor and Government discount rates in the O&G industry are typically
different as the cost of capital for a government is usually lower than for an energy
company (Researcher’s experience, 1992-2021). The Contractor Discount Rate used
in this research is represented by a uniform distribution with an upper bound 10.88%
and a lower bound 7.04%, based on the weighted average cost of capital (WACC) for
O&G companies listed in Hegar’s analysis (2022). The distribution is based on the
100
mean of the O&G companies' WACC which was 11.94%. Inflation of 2.98% (based
on a US historical average from 1923 to 2022; Macrotrends, 2023) was deducted to
arrive at a real mean rate of 8.96%. The range for this analysis represents the mean
+/- two standard deviations (0.96; Hegar). The Contractor Discount Rate does not
vary with the risk of the project simulated in this analysis as the project is
hypothetical and does not exist in any specific location. Future analysis could be
refined to encompass varying Discount Rates based on project risk profile.
The Government Discount Rate uses the Contractor Discount Rate distribution
less 2%. The researcher knows from personal experience that NOCs typically use a
lower discount rate than publicly traded companies. From that experience the
researcher knows that some Governments may choose to use a 0% discount rate if
they are not contributing any capital to the project, then their NPV is an undiscounted
sum of cash flows. This research does not comment on the correctness or logic of that
policy. Since discount rates are typically held confidential, no literature has been
found as evidence of an appropriate rate for this analysis. Based on researcher
experience that governments using a non-zero rate tend to use a rate approximately 2%
lower than company rates, Contractor Discount Rate less 2% was selected. This results
in a uniform distribution bounded by 8.88% and 5.04%. Additionally, setting the two
parties' discount rates to different values will allow the researcher to gain insight into
how the parties might view a project differently and will demonstrate that the NPV of
the project can vary depending on how the cash flow is split between the parties.

Inflation
The inflation rate used in the model is 0%, for the following two reasons. The
costs in the model are already stated in 2032 dollars and should not be subject to
inflation. Commodity prices such as oil, gas, and power are affected more strongly by
market forces than by inflation and it is hard to see an inflationary effect. For example,
the NYMEX power futures prices from 2003 to 2019 in Figure 10 show a downward
trend, though with an R2 of only 33% the trend is very weak, and it seems other factors
besides inflation are more strongly influencing the prices. 0% inflation has the added
benefit of assisting with ease of auditing calculations.

Discounting Year
The research was carried out in 2023, so that year is used as the discounting year.
Depreciation
The PSA-user countries employ several different depreciation methodologies in
O&G (Wood Mackenzie); by far the most common is straight-line depreciation. Of
the 80 countries studied, 57 use straight-line depreciation. In this method, the same
amount is depreciated every year over the useful life of the asset or a defined number
of years. Of the other 23 countries, ten allow capital expenditures to be expensed and
seven use the unit of production method or declining balance method. Unit of
production is based on depreciating the costs in line with the proportion of total oil or
gas produced each year over the life of the field. Declining balance is an accelerated
depreciation method whereby more depreciation is taken in the early years of the
asset’s life. The remaining six countries use hybrid or other methods. The range of the
number of years over which the 57 countries allow straight-line depreciation is 2 to10
years, with the mean being 5.55 years and the most frequently occurring number of
years being five (30 instances), followed by four (12 instances) and ten (10 instances).
The exact tax rules would be set up as part of a government’s initiative to commence
leasing for OWE and would be studied in greater detail at that time to select the
optimal depreciation method. For this research, the most frequently occurring method
is modelled: 5-year straight-line depreciation.
Output Variables
Output variables are Contractor NPV and Government NPV as this study aims to
investigate both the Contractor and Government perspectives. These two output
103
variables are calculated by the cash flow model. Annual cash flow is calculated taking
into account gross revenue, based on power generation at that year’s prevailing price,
deducting costs, and then splitting that revenue between the Contractor and
Government based on the contract terms (Royalty, CRC, CPS, Uplift Rate and
Corporate Income Tax). Each of the two parties’ net cash flow is calculated and
discounted at the relevant discount rate. The discounted cash flow stream is summed
for each party’s NPV.
Economic Viability of OWE under PSA-like Terms
RQ1 investigated whether the wind farm was characterised by a positive NPV for
both the Contractor and the Government. The cash flow model was run 100,000 times,
the NPVs were captured for each trial in the file Results_20230901.csv, and the data
were loaded into Stata to run the T-tests to test hypotheses H1-1 and H1-2, namely:
H1-1: The mean Contractor NPV is positive.
H0 is that Contractor NPV is equal to 0.
Ha is that Contractor NPV is greater than 0, and:
H1-2: The mean Government NPV is positive.
H0 is that Government NPV is equal to 0.
Ha is that Government NPV is greater than 0.
Effect of Contract Terms and other Independent Variables on NPVs
The cash flow model was run 100,000 times, the NPVs were captured for each
trial in the file Results_20230901.csv, and the data were loaded into Stata to run
the multiple regression to test RQs 2 and 3, whose hypotheses are:
104
H2-1-1: Royalty Rate is expected to have a statistically significant negative
impact on Contractor NPV.
H2-2-1: Royalty Rate is expected to have a statistically significant positive impact
on Government NPV.
H2-1-2: Cost Recovery Ceiling is expected to have a statistically significant
positive impact on Contractor NPV.
H2-2-2: Cost Recovery Ceiling is expected to have a statistically significant
negative impact on Government NPV.
H2-1-3: Contractor Profit Split Rate* is expected to have a statistically significant
positive impact on Contractor NPV.
H2-2-3: Contractor Profit Split Rate* is expected to have a statistically significant
negative impact on Government NPV.
* The rate quoted is the proportion that goes to the Contractor. Government Profit
Split Rate is 100% minus CPS.
H2-1-4: Tax Rate is expected to have a statistically significant negative impact on
Contractor NPV.
H2-2-4: Tax Rate is expected to have a statistically significant positive impact
on Government NPV.
H2-1-5: Uplift Rate is expected to have a statistically significant positive impact
on Contractor NPV.
H2-2-5: Uplift Rate is expected to have a statistically significant negative impact
on Government NPV.
105
H3-1-1: Contractor Discount Rate is expected to have a statistically significant
negative impact on Contractor NPV.
H3-1-2: Contractor Discount Rate is not expected to have a statistically
significant negative impact on Government NPV.
H3-1-3: Government Discount Rate is expected to have a statistically significant
negative impact on Government NPV.
H3-1-4: Government Discount Rate is not expected to have a statistically
significant negative impact on Contractor NPV.
H3-2-1: The average Price is expected to have a statistically significant positive
impact on Contractor NPV.
H3-2-2: The average Price is expected to have a statistically significant positive
impact on Government NPV.
H3-3-1: Average Power Generation is expected to have a statistically significant
positive impact on Contractor NPV.
H3-3-2: Average Power Generation is expected to have a statistically significant

The regression models are as follows:
Contractor NPV = ß1c + ß2c * RoyaltyRate + ß3c * CostRecoveryCeiling + ß4c *

Equation 3: Government NPV Regression Model
The following tests were satisfied:
Ratio of cases to independent variables: there are nine IVs in each regression and
100,000 cases so the requirement for twenty cases per IV is well satisfied.
Outliers: Both DVs were plotted against each of the nine IVs (Appendix 11), and none
revealed outliers, so no data was removed.
Normality: the plot of residuals for the DVs; Contractor and Government NPV were
generated in Excel and were normally distributed. They can be seen in Appendix 12.
Heteroscedasticity & Linearity: Residuals plots for all IVs as related to both DVs
appear linear. Plots can be seen in Appendix 13. No data exhibit the cone shape that
would indicate heteroscedasticity.
Multicollinearity: Variance Inflation Factor was calculated in Stata, and the mean
value for the nine IVs was 1.00 which is considerably less than 10 so multicollinearity
is not an issue. Results can be seen in Appendix 14.
No cases had missing data, n = 100,000.
107
Optimal Contract Terms
Multiple Regression allows us to look at the effects that each of the five contract
terms has on the NPVs over the whole distribution of each IV. In the dataset
Results_20230901, those ranges were rather wide as can be seen in Table 7.
Independent Variable Minimum Value Maximum Value
Royalty Rate 0.00% 27.30%
CRC 35.00% 100%
CPS 0.00% 100%
Tax Rate 0.00% 77.38%
Uplift Rate 30.00% 50.00%
Table 7: The minimum and maximum values for each independent variable
In a negotiation for a new PSA, these ranges would be narrowed quickly. The
Government would likely offer a set of contract terms, pinning the starting point for
each. As negotiations proceed, offers will be made around that starting point and not
utilising the whole distribution used in this research. Therefore, it is also important for
negotiators to have a methodology by which to evaluate the relative effects of the
fiscal levers within a narrower range. This methodology is scenario analysis, in which
up to eight IVs are held at a constant value and the remainder is/are allowed to take a
certain number of fixed values selected by the user. In these analyses the model was
run only 10,000 times for efficiency’s sake.
In this research, both stochastic and deterministic scenario analysis were employed.
108
Fiscal Terms in Depth
As a means to understand how the regression coefficient relates to the individual
effects of each fiscal term over its full range of values, the effect of each term on the
total NPV was studied. This allowed a deeper understanding of each contract term in
isolation – whether the regression coefficient represents the effect of the term at all
values it can take, or whether at the ends of the range the term behaves differently,
and the regression coefficient merely represents an average effect. The IV under
investigation was allowed to take on multiple different values across the same wide
range as seen in Table 7, while every other IV was held constant. A trial was run for
each IV value - and the values for IVs and DVs were collected. The total NPV was
calculated from Contractor NPV + Government NPV, and the change in total NPV
was plotted for each IV value. The dynamics within the cash flow model – the
interplay of the different fiscal levers – were scrutinised to uncover greater knowledge
about the dynamics of each fiscal term. For example, whether the total NPV rises
smoothly with an increase in Royalty rate or whether it rises in “stair steps” caused by
an event occurring in the cash flow model.
Optimising Fiscal Terms
This second type of scenario analysis aimed to discover if a symmetrical change
in a fiscal term IV yields a symmetrical change in the DV, as regression would imply.
For example, a regression coefficient of -10 for the IV Royalty Rate when regressed
on Contractor NPV implies that for a 1% rise in Royalty Rate, the NPV decreases by
10 and for a 1% fall in Royalty Rate, the NPV increases by 10. Four values were
109
selected for each IV to yield three resultant differences between NPVs. Table 8
contains the levels of each IV that were tested.
Independent Variable Mean of distribution
(for reference only)
Levels tested in analysis
Royalty Rate 8.5% 8%, 10%, 12%, 14%
CRC 67.5% 60%, 65%, 70%, 75%
CPS 50.85% 48%, 50%, 52%, 54%
Uplift Rate 40% 38%, 40%, 42%, 44%
Income Tax Rate 31.32% 28%, 30%, 32%, 34%
Table 8: The levels of each fiscal term / IV tested in the optimisation analysis
The total NPV results were analysed for symmetry with regards to rises and falls
in IV values and the Contractor NPV changes were compared to the Government NPV
changes. A comparison was also made, for the sake of interest, between the results of
this analysis and the regression coefficients.
Following this, an example is given, simulating a real negotiation, of how a
change in one fiscal term can be compensated by changes in others from one party’s
perspective, for example, if the Government suggests an increase in Royalty,
damaging the Contractor NPV, how the Contractor might request changes to other
terms to compensate. Both parties’ NPVs were considered – if both parties are better
off after a change in terms, the new set of terms may be the optimal set.
Stochastic Analysis for Negotiation
Having gained a deeper understanding of the behaviour of the fiscal terms and
having found a preferred set of terms during negotiation, the final step, which
combines the two latter techniques, is to re-introduce distributions for the IVs whose
110
values are
111
unknown at the time of negotiation. These are Price, Power Generation, and Cost.
Through an example, this research illustrates the kind of output a decision-maker
could employ prior to committing to the contract. The fiscal term IVs are set to their
average levels as if those were the currently agreed values in an active negotiation.
The distributions used in the multiple regression are re-introduced for Power
Generation, Price, Cost, and Discount Rates. 10,000 trials were run and the
distribution of NPVs for each party is illustrated.
NPV Sensitivity to Project Characteristics
Whilst Price, Generation, and Cost are not negotiated variables, a change in any
of them could render an otherwise economic project unviable, so they are also
important variables for both contract parties to examine. Sensitivity to project
characteristics such as these gives information about the risk profile of the project. It
also guides the Contractor as to which decisions have more impact on the outcomes
than others. For example, if the OWF is highly sensitive to Cost, the most effort
should go into lowering both cost and its variability. If the project is insensitive to
Generation, less time might be put into the siting of the turbines.
In order to study the effect of these variables on the applicability of the contract
terms, scenario analysis was again used. The five fiscal levers were held steady at their
mean values and the price, generation, and cost were set to three levels. Those levels
were: mean + 20%, mean, and mean -20%. 10,000 trials were run each time and the
mean values for IVs and DVs were collected.
112
Qualitative Study
Research Design
The purpose of the interviews was to elicit opinions and ideas as to the
applicability of PSA-like contract terms to OWE from current or former users of
PSAs.
This understanding complements the findings from the quantitative phase; under
which circumstances PSA-like terms can be applied to OWE. Additionally, that phase
studies only the financial contract terms and does not quantify the non-financial terms
discussed in Chapter Two. Discussions with industry professionals who are experts in
PSAs can test the applicability of these other benefits to OWE.
Research Location
The participants were current and former employees of O&G companies and were
located in Texas, West Virginia, Connecticut, and Norway. Due to cost and time
constraints, the setting was seven synchronous virtual video meetings via MS Teams
or Zoom. There was very little control over the physical location of the participants,
being remote, but they were all in their offices or residences. The location of the
participants does not affect their knowledge of the subject matter; all have worked in
international settings whilst exposed to the PSAs they have experienced.
Population
The study population was current and former O&G industry employees with
significant experience in PSAs and at least basic knowledge of OWE. This population
is able to talk in detail about the facets of PSAs and the advantages and disadvantages
to both contracting parties. With their long experience in the industry these experts
113
typically have opinions on the transition and renewable energy, and some experience
with offshore wind.
Sample
The sample of seven interview participants was selected by non-probability
methods i.e., purposive sampling. It was not possible to ensure the representation of
the population of all O&G employees with PSA experience due to the purposive
sampling through personal relationships. However, the participants were carefully
selected to represent different company types within the industry – IOCs (two), NOCs
(three), and industry consultancies (three). They were selected for their experience
working in detail with PSAs. The study has limited generalisability based on the small
sample size.
The participants were recruited through personal relationships with the
researcher. One was an industry peer, three were former consultants, and four were
ex-colleagues. No research was done until the research proposal was approved, and
the IRB requirement was satisfied, but initial contact to canvas willingness was made
prior to IRB approval in June 2023. IRB approval was attained in two tranches: first
to interview American citizens, and second to interview Norwegian citizens
(ultimately only one agreed to participate).
The sample demographics do not mirror society as a whole but are fairly
representative of white-collar O&G workers and retirees, who would have experience
with PSAs. The sample is biased towards Americans due to the simpler IRB approval
process in which cross-cultural considerations are not relevant. Sample demographics
can be seen below in Table 9.

Data Collection
Verbal statements (and their accompanying non-verbal cues) were collected
through semi-standardised interviews, recorded with MS Teams or Zoom. The RQs
could not be answered through observation. RQ6 could have been investigated
through documentation, as it is a well-studied area, but the research would have
115
lacked opinions and discussion of a new concept (RQ7) had it been performed
through studying historical documents.
Pilot Interviews
Prior to IRB approval, two pilot interviews were conducted to test the questions.
At that stage, the participants were to be Government or Energy Ministry employees.
The pilot interviewees were industry ex-employees posing as Government employees
to test the questions. The questions underwent revision after each pilot until finalised.
Although the population and sample changed between the pilot interviews and IRB
approval, the questions were still relevant, with only minor wording changes for the
new audience.
Standardised/Structured Interview Protocol
An interview protocol is more than a simple list of questions; it outlines the
procedure of the interview and includes a script for the interviewer. It prompts the
interviewer to provide an introduction, to collect informed consent, and serves to
remind the interviewer the key demographic and research information to collect
(Jacob & Furgerson, 2012). The interview script can be found in Appendix 15. The
interviews were focussed in order to elicit deep reactions and context, and questions
were open-ended to spark discussion and idea generation. An introduction was given,
followed by the protocols (informed consent, confidentiality, data privacy and
sharing, the research process, and an offer of the research conclusions) such that
consent was achieved. Demographic questions followed, then the discussion
questions were asked. A survey would not have been appropriate for this exploratory
research (Jain, 2021), despite the fact a survey would have been quicker than
116
interviewing and transcribing multiple interviews. Nor would interviews with closed-
ended questions and a fixed script have been appropriate as they generate numeric
data rather than eliciting the participants’ experiences with PSAs (Ivankova &
Cresswell, 2009) which is required for Grounded Theory. The questions were focussed
but gave the participants room to be creative, to consider new ideas as they occurred,
and to jump between topics to follow their mental flow.
Response Recording
The researcher did not take notes during the interview in order to focus on the
conversation and listen intently. Since the interviews were recorded (and a backup
audio recording was made simultaneously with a hand-held dictaphone), notes were
not required during the interview. Additional follow-up discussion could have taken
place if information needed to be expanded and/or clarified as appropriate and
relevant. Initial impressions were noted immediately after the meeting.
The researcher was the interviewer, and for three of the seven interviews, a
colleague was present to confirm the researcher’s understanding via a second set of
eyes and ears. The debrief after those interviews confirmed the researcher had
correctly interpreted the data and highlighted any instances in which the researcher
could have led the direction of the conversation. The interviewer was mindful to listen
rather than lead the conversation, and speak only to provide support, move the
conversation, or inquire in more depth when merited. There were no such instances
of leading in the three observed interviews. There were no instances in which the
interview could not be conducted in English.
117
There was no time limit imposed on the interviews and six of the seven were
completed within 60 minutes. Transcriptions are available in raw, unedited form, and
in a sanitised form to assist clear understanding of the participant’s meaning.
Data Transcription
Standard orthography was employed during transcription – correct English
spelling and punctuation - with the addition of colloquialisms and industry-specific
terms where merited. Non-verbal/linguistic cues – paralinguistics, prosody, and
extra-linguistics were captured for all interviews but only transcribed for one
interview – the additional captured data did not add any useful information to the
coding process, so non-verbal/linguistic cues were not transcribed for the remaining
interviews. Transcription was in Otter.ai and each interview received three iterations
of listening to the raw audio whilst reviewing the automatic transcription to ensure
the most faithful transcription possible. In one case, there were unintelligible words
captured and noted in the transcription as “[unclear]” but in the researcher’s opinion
this did not dilute the participant’s meaning. In three cases, a second, sanitised
transcription was made. Stuttering and repeated words threatened to make coding
difficult, so those repetitions were deleted. The deletions did not diminish the
participants’ meanings.
Data Analysis
The approach to the qualitative data analysis is guided by the Straussian school
of Grounded Theory. Grounded theory was derived from pragmatism (Strauss &
Corbin, 1990) but the Thematic Analysis method that was employed is also
considered applicable to post-positivism (Clarke & Braun, 2017), the two stances of
118
this researcher. As Strauss permits, the literature review was performed and provides
knowledge about many topics adjacent to the research question, such as renewable
energy, offshore wind, hydrocarbon contract terms, and current trends in leasing,
subsidisation, and costs in OWE. It does not provide any background on the research
question itself, which has never been asked before.
Thematic Analysis is a flexible approach that can be applied to many data
sources, including interviews, and any dataset size, from a single case study to large
interview fields (Clarke & Braun). It is well applicable to this dataset of seven
interviews where themes are sought.
The Straussian approach calls for three stages of coding: open, axial, and
selective (Strauss & Corbin).
Open Coding
The first interview was coded immediately after transcription, employing open
coding. The interview questions were adjusted in very minor ways (wording only) to
function better for subsequent interviews. The second to seventh interviews were
coded shortly following transcription and the codebook was expanded as new themes
emerged. By the sixth interview saturation was being reached in the sense that new
topics were not being introduced, and the seventh confirmed concepts but did not add
new ones.
The concepts were organised and coded using NVivo software. Each transcript
was coded twice at the open coding level – once for O&G questions and once for
offshore wind questions. Each transcript was imported twice, labelled O&G or OWE,
and coding for O&G was performed on the O&G cases, whereas coding for the
119
transition and offshore wind was executed on the OWE cases. This was so that the
two intents can be kept separate when running NVivo queries – for example, Cost
Recovery was a common theme in both discussions and the researcher wished to be
able to query it as a part of O&G alone, and as a part of OWE alone, to see if the
changing context made a difference to how the participants spoke of the theme.
No prior coding of interviews on the topic of PSAs has been identified in the
literature so the codebook is original.
Memoing was used to capture the handling method of each transcript and any
comments of the observer. The raw audio and video were referred to in a few
instances to confirm or triangulate what was being said with non-verbal reactions and
ensure correct interpretation. Consistency was a concern prior to the research as it
used open-ended discussions – the concern was if the first interviews revealed ideas
worthy of exploration subsequently, but not envisaged at the pilot study stage or in
the question script. This concern did not come to fruition. No concepts emerged from
the interviews that caused the need for subsequent script changes. The only script
changes were to improve the clarity of the questions.
The transcripts were studied for the advantages and disadvantages of using PSAs
for O&G leasing to contracting parties (RQ6). Some advantages (or disadvantages)
affect both parties, and in other cases an advantage to one is a disadvantage to the
other. The transcripts were further studied for the participants’ opinions on the
transition and OWE, and how the features of the PSA could be applied to offshore
wind (RQ7). Each participant discussed the advantages and disadvantages they could
see from using a similar leasing system for offshore wind. Given the inductive coding
120
approach, data could be coded to several codes simultaneously depending on whether
it touched multiple themes.
After the seven interviews were completed, constant comparison was employed
(Strauss & Corbin). Each coded transcript was reviewed to ascertain if early
interviews should be coded to new codes that arrived later. Approximately fifteen
data points were re-coded or coded to additional codes.
The interpretation is empathic – the researcher did not seek to impose ideas on
the participants and given that she may be seen as an authority figure, care was
exercised. Suspicious interpretation was available to be employed to combine
responses containing contradictory ideas or responses based on incomplete or
incorrect knowledge. This only happened in one instance, where a respondent was
working on an incorrect assumption about OWE.
The code book as it stood after this phase can be seen in Appendix 17.
Axial Coding
In the second level coding, inductive methods were used to seek patterns in the
data; similarities, differences, frequency, sequence, correspondence, and causation
(Saldana, 2021). Despite the importance Strauss & Corbin place on similarities and
differences, they were not under investigation per se, as the goal is not to compare
opinions but to build a theoretical concept from multiple participants. Differences
provide the breadth of concepts and similarities provide the importance of a concept
among the whole. The frequency with which each concept arises was of interest, as
it could indicate importance. An idea may be mentioned multiple times by a few
participants or mentioned a few times by all participants. The sequence in which
121
participants raised topics may be of importance – a topic that is raised first by several
participants may be a key concept. The segue between topics may be interesting – or
may just indicate the participants’ thought patterns, for example, perhaps they are
thinking through the contract in page order as they speak. Sequence may also indicate
linkage between topics, for example, Cost Recovery and Profit Split are often spoken
of in the same breath as they are key differentiating characteristics of a PSA.
Causality was not a key concern in this research as an explanation of a behaviour was
not sought. The goal was the generation of key themes about a business proposition.
Explanatory power is important – why a certain concept is important to the
participants, and to the research question, but this research does not seek to identify
causes for the existence of that concept. The fact it is a characteristic of a PSA is
accepted by this research.
Although induction is complex and risks lacking focus, with the small number
of interviews to handle, it was manageable.
In the axial coding stage, codes were merged and moved as needed. Codes
related to the order of participants’ responses were added. In the open coding, the
researcher sought concepts and had not yet focussed on the importance of the
concepts. The code book as it stood after this phase can be seen in Appendix 18. A
coding query was next run to ensure all data had been coded to at least one code. The
few statements that had been missed that were not simply demographic responses or
punctuation were coded.
122
Selective Coding
In this final stage, the codes were further refined and pulled together to create
the over-arching story (Strauss & Corbin). The codes are no longer “buckets” of data
but systematically relate to one another. Where there were gaps in the story, the
transcripts were searched for answers.
The final code book be seen in Appendix 19.
Querying the Data
NVivo standard queries such as Word Frequency, Word Trees, Coding Query,
and Matrix Coding Query were employed to investigate the data, as well as
mapping the codes in PowerPoint, and analysing the data simply by reading and re-
reading. The use of these tools can be seen in the Results and Discussion section.
Methodological Integrity
In the quantitative study, the internal validity of the cash flow model used for
simulation was achieved through an audit of the model from both the major professor
and a second committee member, and through the replication of KP’s 2004 study.
The regression coefficients achieved by KP and in this research are all in the same
(expected) direction, and of similar relative magnitudes (please refer to Table 5). The
coefficients will never exactly match because KP provided neither their model nor
their detailed accounting assumptions. The model used in this research will differ,
though not significantly. Since neither KP’s nor this model are intended to replicate
a specific country’s PSA, they pull on the most commonly found contract terms, but
the researcher and KP may not have selected the same exact terms.
123
In addition, to ensure internal validity, the inputs into the model (please refer to
the section on meta-modelling) were selected from credible sources such as Wood
Mackenzie, the IEA, NREL, and Statista to ensure that conclusions drawn from the
model’s output can be relied upon.
Quantitative results are not generalisable outside the range of the input values.
However, external validity is achieved for a specific situation that matches the input
ranges used. A country which both has the wind potential to match the simulated
OWF at the cost ascribed to it and can sell the power within the price range simulated,
could look to this research’s conclusions to guide on applicability of PSA-like terms.
However, for a power price outside the range used, or a lower capacity factor than
modelled affecting the wind farm operation, a different data set would be collected
from the simulation, and results and conclusions may change. Before investing in
projects such as these, the best available inputs should be collected for the specific
context. For example, should a government in Nigeria be interested in these contract
terms, they must adapt the wind farm costs, power price, and generation profile to
local conditions.
Considering reliability, it is not possible to replicate these results exactly. The
simulation involves calculating the cash flow anew with each trial and the chance of
repeating the exact set of 100,000 or 10,000 data points is extremely small. For
example, three consecutive runs of 10,000 trials each yielded the following mean
NPVs in Table 10; the total NPVs are similar though the split between parties varies:
124
Mean of 10,000

Total NPV
Set 1 US$340MM US$1213MM US$1553
Set 2 US$274MM US$1313MM US$1587
Set 3 US$266MM US$1277MM US$1543
Table 10: Mean NPVs over three sets of 10,000 trials
Additionally, confidence can be placed in the T-tests with P-values of 0.0000
and in the multiple regressions with R2s of 84.41% and 90.16%. A sample size of
100,000 trials further improves the chance of avoiding bias.
Assessing validity in qualitative research is a debated topic. Current thinking is
that a single prescribed method to assess validity may in fact prevent quality analysis
due to the diverse nature of qualitative research (Welch & Piekkari, 2017). Further,
Hayashi et al (2019) recommend a processual rather than a traditional quantitative
approach to assessing validity. This means that the quality of the research is visited
and revisited throughout the work rather than by an ex-post test. For this reason, the
calculation of Cohen’s Kappa was not attempted, as the researcher feels it would be
fraught with errors given the lack of availability of a co-researcher with in-depth PSA
knowledge or a participant with a working knowledge of coding and NVivo.
Welch & Piekkari suggest the use of multiple sources of data and a chain of
evidence to demonstrate construct validity. Concerning the former, seven participants
were interviewed, and common themes quickly emerged. Saturation was achieved by
the sixth interview, indicating between-participant agreement. Data credibility was
achieved within-participants through triangulation with non-verbal cues where there
125
was any doubt in the researcher’s mind as to the intent of a participant’s comment.
The interview observer was able to confirm the researcher’s understanding of the
participant and that she did not lead the participants or in any way bias the responses.
During interviews, the researcher was careful to listen and only direct the
conversation to the extent that extra detail or explanation was required, or to
encourage a participant to examine all the issues and not get overly focussed on one
contract term. The researcher was aware that she could be biased toward the research
topic (PSA-like terms being applicable) and did not want participants to be swayed,
so she limited her verbalisation to that strictly necessary to keep the interview moving
and on topic. As a post-positivist, validity through the lenses of the participants and
people external to the study can be achieved through member and peer checks
respectively (Creswell & Miller, 2000). As such, a peer check was performed, which
confirmed that the findings and conclusions could feasibly have been drawn from
interviewing O&G professionals. The demographic data of the peer check participant
and some of the comments made in the interview can be found in Appendix 16. The
process used to interview the peer check participant was identical to that employed
in the seven interviews.
Regarding the process used, the researcher maintained multiple, carefully
organised copies of data to ensure no loss. Transcriptions are available in raw,
unedited form, and in a sanitised form to assist clear understanding of the participants’
meanings. Codebooks at the end of each of the three stages of coding are captured and
available in Appendices 17 to 19.
126
Internal validity was achieved through the three-stage coding process, extracting
themes and revisiting transcripts coded early as the codebook advanced. The
questions were focussed but gave the participants room to explore any topic or
tangent. There was no time limit set on the interviews and six of the seven were
completed within 60 minutes. A member check interview was not possible due to the
lack of availability of participants.
Transferability, or Welch & Piekkari’s last category, external validity, is implied
by the quick pathway to saturation in coding. Within six interviews the major themes
had been elicited and repeated by several or all participants. Since these participants
have global experience, covering many of the 82 PSA-using countries (Wood
Mackenzie), their comments can reasonably be assumed to be applicable to any PSA-
using country, and depending on the context, could well apply to any country, and
even to other renewable energy sources. Replicability of results is also more likely
following this quick pathway to saturation. Since this is the first work on the
applicability of PSA- like terms to OWE, there is no extant literature to which to
compare the results.
Confirmability was achieved by the fact that similar opinions came from
participants from two countries (USA and Norway) and from three company types
(NOC, IOC, and consultancy).
The qualitative research could be strengthened by interviewing governments or
energy ministries, to get the perspective of both parties to the contract. Interviewing
NOC employees goes a small way to achieve that, hence the selection of two
participants who work for NOCs. A bigger sample size would also add richness, but
127
saturation was reached with the seven interviews performed. Participants from more
than two countries may also yield more richness.
Resources Utilised
MS Excel was used for the simulation and Stata was used for the statistical
analysis. The latter’s licence required funds allocated to the URI DBA programme.
NVivo was used for the qualitative analysis, again, the licence required funding.
Otter.ai was used for transcription, the licence was kept on a month-to-month basis to
preserve programme funds. The literature review was conducted using Google
Scholar, the URI library, DBA class material, other web-based resources, and in some
cases direct contact with authors. The researcher’s database of 362 articles was held in
MS Excel and MS Word. The dissertation was written in MS Word and presented
using MS PowerPoint.

CHAPTER 4
FINDINGS
Economic Viability of OWE under PSA-like Terms
The results of the T-tests for the null hypotheses that Contractor NPV and
Government NPV (variables crnpv and gvnpv) are equal to zero are in Table 11. The
sample size is 100,000 trials and each test has one variable; degrees of freedom are
99,999.
Table 11: One-sample T-test results for the variables crnpv = 0 and gvnpv = 0
129
The first test, for Contractor NPV, indicates that the underlying mean is not equal
to 0 with a significance level of 0.0000. The test indicates that the NPV is greater than
zero with a significance level of 0.0000. The mean NPV for the Contractor is
US$234MM implying that on average, the rational Contractor would participate in this
project. The 95% confidence interval (CI) for the mean is US$232MM to US$236MM
– a narrow range – not surprising given 100,000 data points. The CI for a 500-point
data set such as KP analysed would be much wider. This CI means there is a 95%
chance the true mean falls in this range. However, the standard deviation of
US$302MM implies that there are instances in which the project does not yield a
positive NPV, in which case the rational investor would not move forward with the
project. The mean is rather variable, with the magnitude of one standard deviation
being higher than the magnitude of the mean itself, despite the confidence in the
mean’s accuracy. 31.8% of cases will result in an NPV more than one standard
deviation from the mean, which equates to a negative NPV in the case of mean minus
one standard deviation, 15.9% of the time. In fact, since the mean is US$234MM, the
NPV will be negative at minus 0.77 standard deviations, which will occur more than
15.9% of the time. For this sample, in 22,137 of 100,000 trials (22%), the Contractor
NPV was negative. However, with a positive mean NPV, the only information known
at the time of deciding on the project, the rational decision would be to enter into the
contract, in the absence of a better project competing for financial or human capital.
The second test, for Government NPV, indicates that the underlying mean is not
equal to 0 with a significance level of 0.0000. The test indicates that the NPV is
greater than zero with a significance level of 0.0000. The mean NPV for the
130
Government is US$2,046MM with a standard deviation of US$695MM implying that
it is unlikely that the project does not yield a positive NPV. In this sample, the
Government NPV was not negative in any of the 100,000 trials. A rational
Government investor would participate in this project. The CI for the mean is again a
small range, from US$2,042MM to US$2,051MM.
In fact, when the total NPV is taken into consideration, no projects in this sample
yielded a negative total NPV. The lowest total project NPV was US$343MM, split
such that Government NPV was US$697MM and Contractor NPV was US$-354MM
(a Contractor would not approve this project if it had this data ahead of time). The
highest total project NPV was US$5,816MM, split such that Government NPV was
US$5,473MM and Contractor NPV was US$343MM.
Pursuant to the T-tests, the null hypotheses associated with H1-1 and H1-2 were
rejected and both Government and Contractor means are statistically greater than zero
(RQ1). It can be concluded that under these contract terms, discount rates, generation,
price, and cost conditions, PSA-like terms can be used for OWE. Both contracting
parties will statistically realise a positive NPV and should rationally be willing to
move forward with the project, in the absence of another project competing for
financial or human capital.
Effect of Contract Terms and other Independent Variables on NPVs
Multiple regression was used to predict whether the IVs Royalty, CRC, CPS,
Uplift Rate, Tax, Contractor Discount Rate, Government Discount Rate, Average
Power Generation, and Average Power Price significantly predicted Contractor NPV
131
and Government NPV. The results can be found in Table 12. The sample size was
100,000 trials and the degrees of freedom were 99,990 given nine IVs and one DV per
test. The dataset used was Results_20230901.

Table 12: Multiple regression of Contractor NPV and Government NPV on nine IVs
The overall regressions were statistically significant (R2 = 0.8441 for Contractor
NPV, F(9, 99990) = 60,149.79, p = 0.0000) and R2 = 0.9016 for Government NPV,
F(9, 99990) > 99999.00, p = 0.0000).
It was found that Royalty, CRC, CPS, Uplift Rate, Tax Rate, Contractor Discount
Rate, Average Power Generation, and Average Power Price significantly predicted
Contractor NPV. See Table 12 for β-values (coefficients), p = 0.0000 in all cases.
132
It was found that Royalty, CRC, CPS, Uplift Rate, Tax Rate, Government
Discount Rate, Average Power Generation, and Average Power Price significantly
predicted Government NPV. See Table 12 for β-values, p = 0.0000 in all cases.
The null hypotheses associated with hypotheses 2-1-1 through 2-2-5 and 3-1-1
through 3-2-2 were rejected following the multiple regression analysis. The IVs listed
above associated with those hypotheses have a significant effect on NPV. Note that
the null hypotheses associated with H3-1-2 and H3-1-4 were also rejected; the
expectation was that no significant effect would be found. Indeed, it was found that
Government Discount Rate did not significantly predict Contractor NPV (β =
11.8199, p = 0.727) and that Contractor Discount Rate did not significantly predict
Government NPV (β = 68.19003, p = 0.273). This is not a surprising result as
Government Discount Rate is not used in calculating Contractor NPV, nor is
Contractor Discount Rate used in calculating Government NPV.
The regression models are tabulated below in Table 13. Note that if using the
models for prediction purposes all IVs commonly expressed as percentages (all except
Average Price and Average Generation) must be expressed in decimal form.

Sense-check of Regression Model
In order to test the regression model, consider a case with the inputs in Table 14
below (column “Value for Test”). These IV values are close to (rounded up or down)
the mean values for each variable in the dataset Results_20230901. These values have
no specific meaning, they are just selected for the convenience of double-checking the
regression model before proceeding with the analysis. If the DVs are calculated using
the regression model, Contractor NPV would be US$151MM and the Government
NPV would be US$1998MM. These are well aligned with the mean NPVs of
US$151MM and US$1980MM respectively from the same dataset
(Results_20230901), and the researcher is comfortable that the regression equations
can be used for predictive purposes.

Regression Discussion
The results indicate that while using PSA-like terms for the OWF analysed, and
for a 1% change in rate, Discount Rate has the largest effect on the NPV for both
parties. Royalty Rate, Tax Rate, CPS, and Average Price have the next largest effect.
The smallest effects are from CRC and Average Generation. However, since absolute
values of the discount rates vary by less than 4%, and the fiscal terms’ absolute values
vary by up to 65% in the case of CRC, the reader should be cautioned against placing
too much importance on the discount rate.
Secondarily, the discount rate is not a negotiated term in the contract - it is an
internal factor selected by the investor. Comparing the effect of the terms negotiated
135
by the counterparties – namely Royalty, CRC, CPS, and Uplift Rate (and potentially
Tax, though that is often legislated) is more relevant and can make a deal to lease
seabed for an OWF more, or less, attractive to each party.
An interesting discovery from this regression analysis is that for a 1% increase in
certain fiscal levers, the result is not the same for both parties. The two parties’ NPVs
are not equally sensitive to a change in the value of an IV. This is an important factor
to consider when negotiating the PSA. Ceteris paribus, for a 1% increase in Royalty
Rate, Contractor NPV decreases by US$12.52MM, but Government NPV increases by
US$17.61MM. Thus, a negotiated change in Royalty rate is of more value to the
Government than it is a detriment to the Contractor. The Contractor could compromise
by decreasing the Royalty Rate, sacrificing US$12.52MM but get a concession from
the Government of greater value in return, as the Government views that sacrifice as
worth US$17.61MM.
Ceteris paribus, a 1% increase in the CRC has a similar magnitude of beneficial
effect to the Contractor as it has a detrimental effect on the Government. It adds
US$2.89MM to Contractor NPV and removes US$3.24MM from Government NPV.
The two parties should view a percentage change in the term similarly.
Ceteris paribus, a 1% increase in Uplift Rate increases Contractor NPV by
US$2.09MM and decreases Government NPV by US$3.05MM – again the parties
may view this similarly.
Ceteris paribus, a 1% increase in the CPS has a less detrimental effect on the
Contractor (loss of US$10.24MM from NPV) than it does a benefit to the Government
136
(addition of US$15.96MM NPV), so again, a crafty Contractor would sacrifice a
percentage point in CPS to gain something of more value.
Finally, ceteris paribus, a 1% increase in the Tax Rate decreases Contractor NPV
by US$10.23MM and raises Government NPV by US$15.80MM, so if the Tax Rate is
negotiable, the Contractor stands to lose less by a Tax Rate rise than the Government
gains.
Looked at in combination, a Contractor prepared to accept a 1.2% rise in Royalty
Rate (losing US$15.02MM) may wish to negotiate a 1% increase in all three of CPS,
Uplift Rate, and CRC (which results in a combined gain of US$15.22MM). This may
be acceptable to the Government which gains US$21.13MM on the new Royalty Rate
and loses US$22.26MM on the other terms.
It is also interesting to note that in the previous example, a gain of approximately
US$15MM to the Contractor represents 8.3% of their total NPV (US$182MM; mean
NPV the dataset Results_20230901) whereas the equivalent US$22MM for the
Government represents only 1.1% of their total NPV of US$1980MM (mean NPV
from same dataset). This means that the rational Contractor feels more sensitive to
changes in the negotiated rates than the Government.
The other non-contract terms affecting the NPVs are Power Generation and Price.
Ceteris paribus, a 1% increase in Average Power Generation increases Contractor
NPV by US$0.24MM and increases Government NPV by US$0.61MM. It is intuitive
that as more power is produced for sale, both parties benefit financially. It is also
natural that the Government should accrue a larger benefit since they take over 90%
of the total NPV (from Results_20230901; total NPV is US$2161MM, of which
137
US$1980MM flows to the Government). Whilst it is important to know that higher
power generation increases cash flow, it is a factor that affects the site placement and
engineering details of the wind farm, not the contract negotiations.
Similarly, Average Price is an important factor in the NPVs, but also not
controlled by the parties to the PSA-like contract. Ceteris paribus, for a 1% increase in
Average Price, Contractor NPV increases by US$7.26MM, and Government NPV
increases by US$18.33MM. Again, the Government has more to gain from a price
increase in absolute terms but is less sensitive to a price change. The 1% rise in price
increases the Contractor NPV by 3.8% (from US$182MM to US$189MM, using the
mean of Results_20230901) but increases the Government NPV by only 0.9% (from
US$1980MM to US$1998MM, using the mean of Results_20230901). The price for
which the power is sold could be tied to market rates which float daily or could be
fixed at the time of OWF construction through PPAs. These issues should be carefully
considered but like power generation, are not part of the negotiations between
Contractor and Government for the leasing of the seabed.
A final note follows on the discount rates and their effect on the total NPV of the
project. Since the Government Discount Rate is lower than the Contractor’s, the
maximum project NPV can be attained if the entire cash flow is allocated to the
Government. The cash flow would be discounted at a rate in the range of 5.04% to
8.88% rather than the Contractor’s range of 7.04% to 10.88%. A quick comparison,
running 10,000 trials with the following changes revealed the mean NPV results in
Table 15:

Table 15: Cases illustrating the change in total NPV when fiscal terms are weighted towards either
party
This illustrates the potential for a high total NPV when the lower (Government)
Discount Rate is applied to it (case 2 is higher than case 1 or 3). However, this is a
hypothetical observation, as the Contractor will not enter the project without being
able to demonstrate a positive NPV. Should the Government and Contractor Discount
Rates be equal, this phenomenon would not be observed and the total NPV would not
vary with the contract terms being biased towards one party or the other.
Within the ranges of fiscal terms in this research, and for the OWF analysed,
PSA-like terms can be used as a leasing instrument. It may also be interesting in the
future to perform the same analysis for an oil or gas field, and the conclusions may
have utility for Contractors or Governments negotiating for O&G leases.
Optimal Contract Terms
Regression would encourage the reader to believe there is a symmetrical rise or
fall in NPV for a +/- 1% change in a given IV. However, for Royalty Rate, CRC,
CPS, and Uplift Rate this does not hold true as shown in the following analysis.

Initially each fiscal term is examined at 1% increments over the whole range used
in this research, to understand its behaviour.
Fiscal Terms in Depth
Royalty Rate
A change in Royalty Rate over the whole range of rates used in the research
(0% to 30%) yields the change in total NPV in Figure 11.
Figure 11: Change in Total NPV for a 1% change in Royalty Rate
Total NPV increases as Royalty Rate rises as more cash flows to the Government,
the party with the lower discount rate. As can been seen, the change in total NPV stays
constant within a certain array of rate changes, then stair-steps to a higher NPV delta
with every few Royalty rate increases. This occurs because the residual revenue after
the deduction of Royalty flows to Cost Recovery. The higher the Royalty, the smaller
the Cost Recovery fund. The Contractor then takes more years to recover its costs.
Every so often, the year in which the cost recovery of capital is completed slips by one
year. As Royalty Rate rises, it can force the final year of Cost Recovery to slip one

year later, or as the rate decreases, the final Cost Recovery may accelerate to one year
earlier. As a portion of recovered capital becomes cash inflow to the Contractor a year
earlier, it is discounted one year fewer, and adds to NPV. Conversely, if the final year
of Cost Recovery becomes later, that cash inflow to the Contractor is discounted by
one more year, and total NPV decreases. At low Royalty rates, when more funds are
available for Cost Recovery, this slippage occurs less frequently. In this dataset,
between 4% and 10% Royalty Rate (seven different rates), the final year of Cost
Recovery remains constant. However, between 25% and 30% (only five different
rates), the year slips three times as the higher Royalty has a more regressive effect on
the project economics.
Cost Recovery Ceiling
A change in CRC over the whole range of rates used in the research (0% to
100%) yields the change in total NPV in Figure 12.

Total NPV is highest at 0% CRC, as no funds are made available to the
Contractor for Cost Recovery, and they are simply divided 50.85%: 49.15% in the
Profit Split phase. Both the Royalty, and 49.15% of the shared profit are subject to the
Government’s lower discount rate. However, as these projects are uneconomic for the
Contractor they would not proceed, netting both parties nothing. As the CRC rises
from 0%, funds are diverted to the Contractor, and it recovers more costs. It discounts
this cash flow at a higher rate than the Government and total NPV drops. At low
CRCs, the decrease in total NPV is around US$4MM for every 1% rise in CRC, as the
money is used instantly by the Contractor. In this dataset, at 22% CRC, the project
becomes slightly economic, but the whole Cost Recovery fund is still used. At 33%
CRC (the start of the break in curve on the chart) the project creates yet more value
for the Contractor, but there are still some unrecovered costs in the final year. Above
34% the unrecovered costs quickly diminish, and the excess (unrequired) Cost
Recovery funds roll over to Profit Split where they are shared 50.85:49.15. In
profitable projects the Contractor’s Profit Split is then subject to Income Tax, netting
the Contractor less than 50.85% and the Government the balance. The change in total
NPV falls from
~US$4MM to less than US$0.25MM as the funds are diverted through Profit Split and
Tax to the Government, who apply the lower discount rate.
Contractor Profit Split
A change in CPS over the whole range of rates used in the research (20% to
80%) yields the change in total NPV in Figure 13. As CPS rises, more money is
diverted to the Contractor, using the higher discount rate, and total NPV drops.
143
Figure 13: Change in Total NPV for a 1% change in CPS
The change in total NPV is very similar over the whole range – in fact, identical
from 20% to 40% at US$-5.38409MM for each change in CPS. At 41% CPS, the
change in total NPV drops to US$-5.38286MM per 1% change, and from 42% to
80% the total NPV delta drops slightly again, to US$-5.38279MM for each 1%
change in CPS. This level of detail would not be the focus of a negotiation. Since the
Profit Split is calculated after the Cost Recovery mechanism has been completed, the
stair-step effect seen in Royalty and Cost Recovery is not seen. However, the
depreciation for tax purposes takes place after the Profit Split is calculated. In this
dataset between 40% and 41% CPS, the last year in which a tax loss carry-forward
(LCF) is taken moves from 2038 to 2037. Once the LCFs are taken, the remaining
cash flow is taxed and flows to the lower discount rate party, the Government. Hence
the smaller drop in total NPV after the LCFs are completed. The total NPV itself falls

as the CPS rises
145
and the Contractor gets a larger portion of the profit. However, the magnitude of the
fall in total NPV decreases as some of the profit is diverted back to the Government in
Income Tax. It is not apparent what drives the small decrease in the drop in total NPV
between CPSs of 41% and 42%. Since the difference is less than US$70 on a multi-
billion-dollar project the researcher considers uncovering the explanation an unworthy
rabbit-hole.
Uplift Rate
A change in Uplift Rate over the whole range of rates used in the research (0%
to 50%) yields the change in total NPV in Figure 14 14. As the Uplift Rate rises,
more money is diverted to the Contractor, using the higher discount rate, and the
total NPV drops.
Figure 14: Change in Total NPV for a 1% change in Uplift Rate
For Uplift Rate, a stair-step pattern can be seen as for Royalty. As the Uplift Rate
rises, the Contractor recovers more cost, and the recovery process takes longer. At
certain Uplift Rates, Cost Recovery shifts out one year, and those recovered costs are

subject to more discounting. Therefore, the change in total NPV becomes smaller.
The stair-steps are evenly spread, unlike they were for Royalty. An increase in
Royalty limits the Contractor's ability to recover costs whereas an increase in Uplift
does not – it allows the Contractor to recover ever more cost without limitation in a
profitable project such as this – hence evenly spread stair-steps.
Income Tax Rate
A change in Tax Rate over the whole range of rates used in the research (0% to
50%) yields the change in total NPV in Figure 15. As Tax Rate rises, more money
is diverted to the Government, using the lower discount rate, and total NPV
increases.
Figure 15: Change in Total NPV for a 1% change in Tax Rate
For each change in Tax Rate, the change in Total NPV is the same. Tax is the
last fiscal division to be made in the contract and the cash flow is simply diverted
from one party to the other. Payment of extra tax does not affect any cost recovery
or loss carry forward mechanisms, therefore stair-steps are not seen.

For the OWF in this research, each IV behaves differently and does not have
the same effect on the DVs across the whole IV value range. Parties negotiating
PSA-like terms for an OWF should be aware of the idiosyncrasies of each fiscal
term in the range of values he/she is negotiating.
Optimal Terms in a Small Range
Now that the behaviour of the terms has been studied over the same large range
used for the multiple regression, smaller ranges are selected as if in active
negotiation.
Royalty Rate
The change in Contractor, Government, and total NPVs as the Royalty Rate
rises in 2% increments from 8% to 14% can be seen in Figure 16 16.
Figure 16: Change in NPV under the four values ascribed to the IV
The total NPV increases as the Royalty rate rises as more cash flow, in the
form of Royalty, is taken by the Government. The Government has a lower discount
rate than the Contractor, so the extra royalty it receives is discounted less and the
148
total NPV goes up. Contractor NPV decreases as the Royalty Rate rises, as the
Contractor pays more royalty. Conversely, Government NPV increases as more
cash flows to it. Each incremental increase in Royalty Rate does not result in an
equal step in NPV. According to the regression analysis performed for RQ2, we
would expect Contractor NPV to fall US$25.05MM with any 2% increase in
Royalty Rate. Here we see that between 8% and 10%, NPV falls US$24.22MM but
between 12% and 14% NPV falls US$24.92MM. This is asymmetrical – the
Contractor has more to lose from a shift in Royalty from 12% to 14% than from a
2% rise from a lower number. The same asymmetry can be applied to the
Government’s NPV. This asymmetry is expected as it was found in the section
“Fiscal Terms in Depth” that the change in total NPV due to a change in the
Royalty Rate differs depending on the starting rate. As Royalty is calculated before
Cost Recovery happens, the Royalty amount affects the funds available for Cost
Recovery. Therefore, a change in Royalty rate affects the whole Cost Recovery
mechanism and may affect the final year in which capital costs are recovered.
In summary, within the range of 8% to 14%, a 2% rise in Royalty Rate
decreases Contractor NPV by US$24.2MM to US$24.9MM and raises Government
NPV by US$34.5MM to US$35.2MM. Either party will want to consider not only
the change in Royalty Rate, but the starting rate from which that change is made.
Cost Recovery Ceiling
In the range of CRC of 66% to 72%, a change in the Ceiling affects the total
NPV little as can be seen in Figure 17Figure 17.
149
Figure 17: Change in NPV under the four values ascribed to the IV
In this range, the Contractor is able to recover all its capital costs within the
first 10 years of power generation, such that the extra ceiling does not provide much
benefit – from US$4.50MM to US$4.77MM in increased NPV. A small amount of
capital cost can be recovered in an earlier year, thereby gaining some time value of
money. Were the unrecovered costs much higher, the distinction would be more
important – should the CRC move from 0% to 2%, the Contractor NPV increases
US$20.4MM as the Contractor can suddenly recover some costs where it could
recover none before. Contrast this with the regression analysis performed for RQ2,
in which we would expect Contractor NPV to rise US$5.78MM with any 2%
increase in CRC.
Cash earmarked under the CRC but not required to cover costs flows to Profit
Split, where it is split 50.85:49.15 Contractor: Government in this scenario.
Because there is little shift of funds from one party to the other between 66% and
72% CRC, there is only a minor change in the total NPV, as little cash flow is
150
moving from the party with the lower discount rate to the one with the higher
discount rate.
As with Royalty, the change in NPV is not by the same amount for each step in
CRC. For the Government, a rise in CRC from 66% to 68% yields a loss of NPV of
US$5.22MM, but that same magnitude of rise from 70% to 72% yields only a
US$4.89MM loss. The reason is the same as for Royalty – as the CRC increases,
the final year of recovery of capital costs accelerates, and each time it moves
forward one year, the total project NPV increases as less discounting is applied.
In summary, within the range of 66% to 72%, a 2% rise in CRC increases
Contractor NPV by US$4.5MM to US$4.7MM and decreases Government NPV by
US$4.9MM to US$5.2MM. Again, either party will want to consider not only the
change in CRC, but the starting rate from which that change is made.
Contractor Profit Split
Conversely, changes in NPV due to a change in the CPS are very close to
symmetrical. In the range of 48% to 54% CPS, it is necessary to look to the twelfth
decimal place to see a difference in the change in total NPV. As expected, for a rise
in CPS, Contractor NPV increases and Government NPV decreases. As cash is
flowing from the lower discount rate party to the higher discount rate party, total
NPV falls, as can be seen in Figure 18.
151
Figure 18: Change in NPV under the four values ascribed to the IV
This symmetry is to be expected in the range 48% to 54% as discovered in the
section “Fiscal Terms in Depth” as the profit split is a year-by-year calculation and
not affected by the loss carry forward mechanism that affects Cost Recovery and
Uplift.
In summary, within the range of 48% to 54%, a 2% rise in CPS increases
Contractor NPV by US$19.0MM and decreases Government NPV by US$29.7MM.
This time the change in CPS is of importance in negotiations, but the effect does not
differ according to the starting rate.
Uplift Rate
In the range 38% to 44 %, changes in Uplift Rate do not affect NPV
symmetrically as can be seen in Figure 19. A rise in Uplift Rate causes Contractor
NPV to increase as it can take more cash flow from the project through the cost
recovery mechanism. Government NPV falls, but by more as cash flow shifts from
152
the low discount rate party to the higher one. This results in a loss of total NPV as
the Uplift Rate increases.
Figure 19: Change in NPV under the four values ascribed to the IV
The changes are not symmetrical, as seen for Royalty and CRC. The reason is
the same – as the Uplift Rate increases, the final year of recovery of capital costs
may fall later. Each time it moves out one year, the total project NPV decreases as
one year more discounting is applied. The symmetry seen in Figure 19 between
38%, 40%, and 42% is merely because those rates belong to one flat section of the
stair-step chart seen earlier in “Fiscal Terms in Depth”. A stair-step is seen between
42% and 44% explaining the differences in the grey bars of Figure 19.
In summary, within the range of 38% to 44%, a 2% rise in Uplift Rate
increases Contractor NPV by US$4.0MM to US$4.2MM and decreases Government
NPV by US$6.2MM to US$6.5MM. As with Royalty and CRC, it is important to
know not only the change in NPV associated with a change in Uplift Rate but also
the starting point, as that affects the delta.
153
Income Tax Rate
As for CPS, changes in NPV due to a change in the Tax Rate are very close to
symmetrical. In the range of 28% to 34% Tax Rate, the reader must look again to
twelve decimal places in the change in total NPV to see a difference. As expected,
for a rise in Tax Rate, Contractor NPV decreases and Government NPV increases.
As cash is flowing from the higher discount rate party to the lower discount rate
party, total NPV rises, as can be seen in Figure 20.
Figure 20: Change in NPV under the four values ascribed to the IV
This symmetry is to be expected in the range 48% to 54%, as discovered in the
section “Fiscal Terms in Depth”. Tax is a year-by-year calculation and not affected
by the loss carry-forward mechanism that affects Cost Recovery and Uplift. Much
as the change in NPV is flat across all Tax Rates, it is symmetrical in this smaller
range. In summary, within the range of 28% to 34%, a 2% rise in Tax Rate
decreases Contractor NPV by US$19.3MM and increases Government NPV by
US$30.1MM. As for CPS, negotiators must be aware of the change in NPV due to a
154
change in Tax, but the starting point from which that change ensues does not affect
the gain or loss of NPV.
Comparison to Regression Coefficients
A comparison was made, for the sake of completeness, between the results of this
analysis and the regression coefficients (Table 16).

Table 16: Comparison of multiple regression coefficients and the results of the scenario analysis of each
fiscal term
The multiple regression coefficients are similar, but not identical, to the results of
the scenario analysis of a small range of each IV. For simplicity, or at the start of a
negotiation, multiple regression could be employed to gain a sense of the impact of
each fiscal term. It would provide an approximation and allow the negotiator to make
broad statements without running the cash flow model each time. Later, when
precision is required during the final stages of negotiation, scenario analysis is a
better choice of tool to assist detailed understanding of the effect of changes in
contract terms.
155
Use in Negotiations
The following example shows the scenario analysis at work in an illustrative
negotiation. Table 17 shows the mean change in each NPV for a 2-percentage point
change in each fiscal term, as analysed earlier in “Optimal Terms in a Small
Range”. To reiterate, a change in Royalty Rate, CPS, and Tax Rate have the biggest
fiscal term impact on the NPVs.
Fiscal Term / IV Mean Change in NPV in US$MM
Total Contractor Government
Royalty Rate 10.29 -24.60 34.89
CRC -0.43 4.64 -5.06
CPS -10.77 18.95 -29.72
Uplift Rate -2.27 4.15 -6.41
Tax Rate 10.77 -19.29 30.06
Table 17: Mean change in NPV for a 2% change in IV value within the ranges discussed above
A suggested change in a term during negotiations that harmed one party could
be recovered by changes to other terms. For example, a proposed 2% increase in
Royalty Rate sees the Contractor forfeit US$24.60MM. This could be recovered in
the following ways (Table 18) or an unlimited combination of fractions of more
than one term:
156
Fiscal Term Required % change Resulting gain in NPV
CRC (option A) +10.60% US$24.60MM
CPS (option B) +2.60% US$24.60MM
Uplift Rate (option C) +6.36% US$24.60MM
Tax Rate (option D) -2.55% US$24.60MM
Table 18: Required changes in three IVs to equal a +2% change in Royalty Rate
A sensible approach to negotiations might be to request a 2% increase in CPS
(to match the 2% rise in Royalty Rate) in conjunction with a 2.72% increase in
Uplift Rate. This would also recover US$18.95MM + US$5.65MM =
US$24.60MM (option E).
The 2% rise in Royalty Rate affects the Contractor NPV differently from the
Government’s – its NPV increases by US$34.89MM (Table 17). Table 19 shows the
effect on the Government NPV of the five above-mentioned counteroffers that the
Contractor might make.
Fiscal Term(s) Change in Rate Change in Government NPV
CRC (option A) +10.60% US$-26.80MM
CPS (option B) +2.60% US$-38.64MM
Uplift Rate (option C) +6.36% US$-20.38MM
Tax Rate (option D) +2.55% US$-39.02MM
Combination (option E) +2% CPS, +2.72% Uplift US$-38.44MM
Table 19: The effect of the four negotiations options on Government NPV
Clearly, options B, D, and E are the worst as they require that the Government
give up more value than it has gained in requesting the Royalty Rate increase.
157
Options A and C, however, allow the Contractor to retain their former NPV whilst
allowing the Government to increase theirs – their loss is smaller than the gain from
the Royalty Rate rise. The Contractor has room to manoeuvre – it could request an
increase in CRC above 10.6% or an increase in Uplift Rate above 6.36% and
increase its NPV whilst also allowing the Government to increase its NPV. This is
the essence of a “win-win” negotiation and the formulation of optimal contract
terms.
The reader with a keen interest in economics will have noticed that the
Government’s desire for a gross Royalty, and its use of a lower discount rate than a
commercial enterprise, are inconsistent. The Royalty gives the Government cash
quickly – from the outset of the OWF coming onstream and before the Contractor
recovers costs. It is perhaps not surprising that a government seeks cash in any
given fiscal period, to balance the national budget and provide for their country.
Cash inflow may be an even higher priority for developing countries, with a weaker
economic base, lower GDP per capita, and less/little access to capital markets. A
desire for re-election may also drive the preference for being seen to gain early cash
flow from lucrative projects harvesting national resources. Yet commonly
governments use low discount rates to evaluate O&G projects into which they are
investing no capital, and in which IRR is therefore meaningless (researcher’s
experience). This discrepancy could be the topic of a dissertation in itself.
Stochastic Analysis for Negotiation
In a real negotiation, the contracting parties would wish to run the cash flow
model with the fiscal terms set to the rates under discussion at the time, and let the
158
other IVs vary within the full distribution considered applicable to the OWF in
question. Here, the fiscal term IVs were set to their average rates to simulate an active
negotiation, and the other five IVs varied according to their distributions. The model
was run 10,000 times (dataset: Results_20231027) and an NPV distribution was found
for each party (Figures 21 and 22).
Figure 21: Distribution of Contractor NPVs
159
Figure 22: Distribution of Government NPVs
The mean of the Contractor NPVs is US$305MM with a standard deviation of
US$144MM and a range of US$-297MM to US$735MM. The mean of the
Government NPVs is US$2,057MM with a standard deviation of US$320MM and a
range of US$912MM to US$3,085MM. These statistics, together with myriad other
data points could be used for decision making. For example, the Contractor may wish
to calculate the proportion of negative NPV results to gauge risk. The NPV ranges
alone offer more sophistication than the single-point NPVs often used in the O&G
industry.
NPV Sensitivity to Project Characteristics
The “base case” is defined as the case where all IVs take their mean value.
Sensitivities to a 20% increase or decrease in the IVs Price, Cost, and Generation are
shown in Figure 23. At the centre of the chart, the US$0 NPV line represents the base

case. Ceteris paribus, a 20% decrease in Generation or Price has a negative effect on
the NPV, shown in red, and known as the “low case”. A 20% increase in Cost (in red,
the “low case”) also harms NPV. 20% increases in Generation and Price, and a 20%
decrease in Cost (“high cases”) have a positive effect on NPV and are shown in green.
Figure 23: The effect of a 20% increase and 20% decrease in Price, Cost and Generation on Total NPV
For this dataset, the change in Generation and Price have equal effects. This is to be
expected as both affect gross revenue, calculated as Generation multiplied by Price. A
20% change in one is equivalent to a 20% change in the other. The total NPV is less
sensitive to a change in Cost. This is interesting to note for the Contractor who may
wish to pay more attention to Price and Generation than Cost when considering risk in
the low cases. High cases are a happy surprise and typically less scrutinised in running
project economics before a decision (researcher’s experience). Generation is partially
under the Contractors’ control in that it designs the maximum capacity of the wind
farm. However, how much wind resource is present at any given time is not under the
161
Contractor’s control. Price can either be completely under the Contractor's control or
162
not at all. If it lets the sales price float with the market price it has no control. If it
enters a PPA or other fixed-price sales contract, the Contractor can have certainty over
the Price and eliminate the risk (and upside) illustrated in Figure 23. To a degree, Cost
can be controlled and known by the Contractor. Contracts will be signed for all
elements of the building and maintenance. Delays and associated cost overruns could
affect total cost but careful management by the Contractor can minimise those.
Future work could re-introduce the stochastic element to this analysis by using a
distribution for the change to the IVs instead of a flat +/-20%. The Contractor and
Government would then know the likelihood of certain events happening.
Another interesting data point is the breakeven mark for each of the IVs. Table 20
shows the percentage change and resultant IV value at which the total NPV becomes
US$0 for each IV, ceteris paribus.
Independent Variable % of mean value at which
total NPV reaches US$0
Resultant value of the IV
Cost 231.14% US$11,365MM
Price 43.27% US$67.84/MWh
Generation 43.27% 2,027.6 GWh/year
Table 20: Percentage changes and breakeven values for Cost, Price, and Generation when total NPV is
zero
As can be seen from Table 20, Cost must more than double to render the project
valueless. Price and Generation (again equivalent for the reason stated above) can fall
to below half their mean values before total project NPV reaches US$0. However, in
all three cases, the Contractor NPV reaches US$0 before the total project NPV
reaches
163
that point. Table 21 shows the split of NPVs between Contractor and Government for
each of the scenarios in Table 20.
Scenario / Independent
Variable
Total NPV Contractor NPV Government NPV
Cost US$0 US$-1,194.89MM US$1,194.89MM
Price US$0 US$-516.97MM US$516.97MM
Generation US$0 US$-516.97MM US$516.97MM
Table 21: Split of total NPV by party when total NPV is zero under the Cost, Price, and Generation
scenarios
Again, the results for Price and Generation are equal due to gross revenue being
the product of the two. In these two scenarios, the split is less uneven between the two
parties than in the Cost scenario. This is not surprising as revenue is split between the
parties by the various fiscal term mechanisms. Cost, however, is entirely borne by the
Contractor, so a 231% increase damages the Contractor’s NPV more greatly.
The Government still has a positive NPV in all cases and whilst it may dislike
the lower NPV, it would rationally still participate in the projects. From the
Contractor’s perspective, however, it is important to know the breakeven points of the
three IVs that cause Contractor NPV to reach US$0. Table 22 shows these results.

Table 22: Percentage changes and breakeven values for Cost, Price and Generation, and
Total/Government NPV, when Contractor NPV is zero
The project can only sustain smaller deleterious changes before Contractor NPV
reaches US$0 and the energy company would decide not to participate in the wind
farm. A 30% Cost overrun or a 23% decrease in Price or Generation renders the
project valueless from the Contractor’s perspective. Since the Government has a
positive NPV in all three cases, there is room to negotiate less regressive fiscal terms
which would better distribute the modest total NPV between the two parties.
Removing Royalty and increasing the Uplift Rate would assist in this goal. For
example, adjusting the “low” Generation scenario, giving it 0% Royalty and 80%
Uplift (vs. the means of 8.5% and 40% respectively) would split the NPV and award
US$144MM to the Contractor and US$1,068MM to the Government. The rational
Contractor would again be willing to proceed.
In summary, this OWF is more sensitive to changes in Cost than Price or
Generation. Marginal projects, where any of those three IVs are close to the breakeven
point, can be improved by fine-tuning the fiscal terms. Where project outcomes are
not known before building the OWF, the contract terms should be tested for both
165
marginal
166
and highly profitable projects. Progressive fiscal terms, such as low Royalties and the
Profit Split found in PSAs, can ensure marginal projects create value for the
Contractor and that most of the upside goes to the Government in a success case.
Views of PSAs for O&G and OWE
Initial Salient Points
Word frequency within the interviews was analysed and the results and
discussion can be found in Appendix 20. In summary, the salient concepts were
similar regardless of whether the participant was speaking of O&G or OWE
indicating the similarity between the two applications. Next, during the axial coding
phase, the first response that each participant gave to the questions was collected as
that may indicate their most important thought. The results can be found in Table

Table 23: Number of times a concept appeared as the first response to a question
These first-raised themes hint at the details of the interviews to be analysed in
the sections below. These include the importance of such concepts as the workings
of the financial and non-financial terms of the contract, the protection it offers, and
the fact it brings together essential and lucrative natural resources with the financial
capacity and skills needed to harvest them.
168
Advantages of PSAs in Oil & Gas
Eight clear themes - advantages of PSAs in O&G - emerged, with two others
each mentioned only once. The first of these lesser themes is the DMO, whereby the
host country is allowed by the contract to buy a typically small portion of the oil
and/or gas production at a discounted price for domestic consumption. The second
is the fact that the Contractor controls the operations, can control costs to the best of
their ability, and apply their preferred safety standards, which are often higher than
local regulations require.
The eight primary advantages were mentioned with the frequencies shown in
Table 24 below.

Table 24: The eight primary themes within advantages of PSAs for O&G, and the frequency with which
they appear
Non-financial benefits provided by the Contractor
According to the participants, non-financial benefits of the PSA are an important,
and unusual (compared to a CA) part of the structure. One participant summarises
169
nicely, describing them as “non-traditional monetary gains that a PSC typically
[includes] like local content… which includes jobs, building infrastructure, education,
schools.”
These benefits include local or national content, where local people and
fabrication facilities must be employed in the construction and operation of the O&G
field. A caveat raised was the inability of an underdeveloped local industry to supply
the goods and services required by the project.
Another benefit is the training and development of local O&G professionals
which allows them to climb the skills curve and eventually perform work as a
Contractor themselves. One activity that helps fulfil this is the secondment of NOC
employees directly into the project, rather than simply as suppliers for local content.
This is accomplished through Government participation in the project, which results
in the training of locals. Another benefit is direct grants to educational establishments
or education budgets to train the next generation of O&G workers in the secondary
and tertiary education systems.
Requirements for local infrastructure benefitting the citizenry such as roads,
harbours, schools, clinics, and water wells may be included. These may be key to the
construction project (such as a harbour or road) or purely for the betterment of the
populace such as schools, clinics, and wells.
Participant comments about these initiatives were “it’s fantastic”, “it’s fair” and
“makes sense”. It was also noted that these benefits are valued more highly by
170
developing countries than developed countries. The latter do not need new
infrastructure, education, or training, and typically use the CA regime, not PSAs.
Host low-risk, low-cost participation
Participants talked about the clause in many PSA contracts that allows the
Government, through the NOC, to take an equity stake in the project. This provides
the learning opportunities - “a training run”- described in the above section. It also
delivers another source of income for the Government – not just through cash flow
from the Royalty, Profit Split, and Tax, but an additional Profit Split from being an
asset owner. NOC participation is carried i.e., the other owners pay their costs, and
those owners recover what they paid from the Government’s Profit Split. This
eliminates the Government’s financial risk and expense in the setting up of the O&G
field, which will be popular with voters. The Government also gains from the time
value of money, as the Contractor makes up-front expenditure on their behalf and the
Government repays it later, from profits.
The intent of the participation in the long run is for a transfer of knowledge to the
NOC to enable it to carry out operations independently in the future, as has been seen
in Brazil, according to one participant. This could be later in the life of the same field,
or it could in replicating the work on a similar new field. Several participants
expressed concern that this process must be done slowly in order that the NOC
becomes fully capable of the intricate and potentially dangerous operations before
taking over. There is typically flexibility in the contract such that if the Government is
not ready to take over, they do not – thereby continuing to enjoy low-risk operations.
171
Another advantage stated is that having an NOC typically makes a country’s
regulatory body stronger as the government has deeper involvement in the O&G
sector. This ties in with Antolin et al’s case study on Brazil and Bolivia.
Cost Recovery
Cost recovery is the unique contract concept that allows the Contractor, who has
made all the expenditures, to recoup their costs from the cash inflow to the project
before any profits are disbursed (Tordo). The amount of cash flow available depends
on the CRC, which can be set to 100%, in which case all the post-Royalty cash flow is
available for cost recovery. However, it is frequently less than 100% to allow some
cash to flow immediately to the profit-sharing pool. Five of the participants
recognised the power of the Cost Recovery mechanism in decreasing the risk for the
Contractor, saying that the “cost recovery… is for the company”, “they [Contractors]
will want that [CRC] to be as high as possible”, and “it provides some assurance to
the investing oil companies that they'll recover these multibillion-dollar investments
typical for an offshore contract”. Another recognised the upside for the Government,
stating a preference for a CRC less than 100%, as it provides early cash flow to the
Government through Profit Sharing. One participant identified that the protection for
the Contractor in Cost Recovery is also good for the Government in that a marginal
project is more likely to go ahead when the Contractor is comfortable. Another
touched on the complexity of Cost Recovery as a downside protection mechanism for
the Contractor, in that the recovery is given in barrels of oil or cubic feet of gas.
Should the commodity price fall, the Contractor will receive more hydrocarbons to
pay back their expenditure than if the oil/gas price was high.
172
Profit Sharing
Six participants identified profit sharing, or profit split (terms used
synonymously) as an important feature of the contract. One expressed that “the well-
constructed PSC [common industry synonym for PSA] tends to redistribute those
returns to the host country… that's the attraction to the PSC structure”. The profit
after Royalty and costs are (re)paid is split by a pre-determined ratio between
Contractor and Government. In contracts in 74 countries such as Angola, Azerbaijan,
Bangladesh, Ecuador, and India, the split is not fixed but moves on a sliding scale
based on IRR, R-Factor (cumulative revenue / cumulative costs), production rate,
revenue, cumulative production, and price (Wood Mackenzie). The common theme
articulated by participants is that the financial upside – the bulk of the profits,
especially when they are high – goes to the Government, to whom the resource
belongs. Two participants commented that energy companies naturally do not like this
feature. Several participants pointed to the poor reputation of O&G companies for
taking advantage of less savvy nations and seeking “super-profits” on O&G projects.
However, one said that this method of profit-sharing acts as a good safeguard of the
nation’s resources, and in turn may allow projects to go forward that the citizens
would not otherwise have welcomed. Several participants cautioned that the profit-
sharing formula must be carefully crafted in order to achieve its intent. Enough of the
revenue must be available to compensate the Contractor through Cost Recovery; then
the remaining revenue must be judiciously split to encourage the Contractor to take
project risks, whilst the upside flows to the resource owner. This upside could occur
in an unexpected high-price environment, when production is higher than expected, or
if
173
costs are lower than expected. Some participants, despite being O&G company
employees, recognised that this situation is fairer than a CA regime, in which the
upside flows to the Contractor. One participant took the concept a step further, in
saying that a government which knows it is benefiting handsomely in an upside case is
less likely to try and re-negotiate the contract. He pointed to the UK regime, a non-
contractual CA regime, as one in which a windfall profits tax has been introduced
multiple times throughout history. This creates uncertainty for the Contractor at the
outset of a project in not knowing exactly how it will be taxed.
As a final note, one participant did remind us that the profit split received by the
Contractor is then subject to Income Tax and is therefore less than it appears in the
contract. Assuming the company is in a taxable position in the country involved, this
is true. This was also noted in the quantitative analysis forming part of this research.
Flexibility, Progressivity, and Fairness of Fiscal Terms
The primary aspect of progressivity of fiscal terms mentioned by five participants
is that the Royalty Rate can remain low because there is another mechanism through
which the Government will receive cash. In a CA regime, the only opportunities for
the Government to take cash from a producing field is through Royalty or Tax. If a
company has many tax deductions available to them, tax may be low, and Royalty is
the only avenue. The incentive for the Government will be for a high Royalty Rate to
ensure the nation some income. However, since Royalty is calculated from gross
revenue and before costs are taken into account, it is a regressive fiscal term, and can
make marginal projects sub-economic very quickly. A low Royalty Rate, that will
ensure all projects go ahead, will not allow the Government to enjoy in the financial
174
upside of a successful project. The Wood Mackenzie data illustrates this point – the
average Royalty Rate for a CA regime is 11.3% whereas for a PSA regime, it is 8.5%.
The participants point to the fact that a PSA can endure a low Royalty Rate, and
encourage marginal projects, but has a progressive term - the Profit Split – which can
be set at a level that allows the Government to take the bulk of the upsides after Cost
Recovery. One participant mentions the inherent fairness that the Government will get
some cash inflow from day one (from the Royalty) plus the majority of the post-cost
profits through profit-sharing “and that is the way they could sell it [the project] to a
poor population”.
The participants also saw two further ways in which the PSA structure
provides flexibility. With five or more fiscal levers at their disposal, there are
myriad ways in which to split the total project NPV, and a good, or optimal way can
be sought.
The second viewpoint holds that since a PSA is a contract, negotiated for every
opportunity, it can vary much more greatly than a country-wide regime such as would
be used for CA. Thus, the PSA can be fit for purpose for one project or area where a
CA cannot. Connected to that, another view offered was that an unsuccessful PSA
offering (if no Contractors bid, or step forward to negotiate) can be changed and re-
offered with different terms without changing the whole legislative regime, as would
happen for a CA.
The participants frequently alluded to the fact that these mechanisms result in the
PSA being a fair contract. One participant went as far as to say, “I tend to think that
more oil and gas people probably would use the word fairness more with a PSC than
they would with a with a concessionary system [CA]”.
175
Lest the reader get too enthusiastic, two participants reminded us that poorly
structured fiscal terms can also create the opposite situation from that which was
intended, and that care must be taken in setting up the contract. This concept was
also illustrated throughout the quantitative research phase.
PSA as a contract
The advantage that a PSA is a contract, and the stability that offers, arose six
times during the interviews. Not only fiscal stability – the Contractor can calculate the
expected NPV for the project or contract area as the terms are known – but also the
assurance of knowing that access to the acreage is unlikely to get revoked. Of course,
this can happen, but is more likely under a CA, where a government elects to make
sweeping changes. An example was the Venezuelan Government which from 2004
re- nationalised oil fields to which ConocoPhillips, Chevron, ExxonMobil, BP, Statoil
Hydro, Petrobras, and Total had rights under the CA regime (Eljuri & Trevino, 2009).
One interesting point made is that PSAs can replace weak or immature legislation
in a poorly developed country. One set of weak or poorly constructed rules applying to
the whole sector could destroy a nascent industry. A country, perhaps a developing
country, might benefit from negotiating each case separately and learning as it does so.
Two participants pointed to the flipside of contract stability - that an agreement
can be re-negotiated if needed, more easily than lobbying for a change in country-wide
legislation. Towards the end of a PSA, close to the end of the field life, the Contractor
might seek changes to the contract to extend the life of the field. For example, if the
Royalty Rate is such that it has rendered the remaining reserves uneconomic, the
Contractor will want to cease production and decommission the field. This leaves
176
resources in the ground which is a disadvantage to the Government. Renegotiation of
one term in one contract can be accomplished easily enough. Contrast this to
renegotiation of a Royalty in a CA regime which could affect all concession holders –
that would be a much harder task.
Finally, one participant mentioned the convenience of the PSA contract as a
manual for operations, or a checklist. All the rights and obligations of the parties are
contained therein (Johnston), and it can be a convenient guide on how to proceed.
Trade Expertise & Knowledge for Resource
A participant explained, “the reason PSAs exist is because you have one party
that has resources and insufficient expertise, and another party that has sufficient
expertise, but needs more access to resources”. It is true that no party – neither
governmental nor business – would undertake to explore for hydrocarbons without
experience and expertise. It is also the case that globally, government ownership of
resources is almost ubiquitous. Granted, experienced companies can be given access to
resources through CAs or other mechanisms, but in none of those instances is there a
trade of anything other than money for resources. PSAs offer the opportunity to trade
access to resources for not only financial payment but also knowledge transfer – a
“give-get” as another participant described it. The details of this knowledge transfer
are covered in the section on non-financial benefits provided by the Contractor. The
key ideas coming out in this theme were that national human capital gets developed
through education, training, development, and secondment (mentioned seven times in
reference to the trade) and through NOC participation in the projects (mentioned four
times). The story of the rise to great success of Petrobras, the Brazilian NOC, through
177
learning from IOCs was given by one participant, “…argue that Petrobras now is one
of the premier deepwater offshore drillers in the world because of the experience that
it had, and … a stake in the contracts”. Another participant more broadly asserts that a
country without “technological sophistication” benefits from this exchange of
knowledge for access to resources. Yet another participant sees this process as a
stepping-stone to NOCs taking over operations later in a hydrocarbon field’s life and
becoming self-sufficient.
Resource Entitlement and Retention
A smaller theme, mentioned eight times, and one unique to the PSA, is that the
host country retains ownership of the resources – the buried hydrocarbons – until a
portion is turned over to the Contractor as re-payment for costs or as Profit Split. As
one participant astutely put it, “politically it’s a very large advantage for them, they
get a lot of trouble internally and politically for selling off the country's resources”. A
second participant alluded to the same, “…give the impression that you are not just
keeping dollars, but you are actually keeping the country's natural resources”. This
may just be optics, but to a proud developing nation suspicious of “Big Oil” entering
the country and putting money before social considerations, it is a “win” for the
country than cannot be gained through other leasing mechanisms.
Disadvantages of PSAs in Oil & Gas
Fewer themes around the disadvantages emerged, and only one had a similar
amount of coverage as the advantages. The four disadvantages were mentioned with
the frequencies shown in Table 25 below.
178
Theme Number of references
Highly complex contract 15
Limited Contractor upside 8
Abuse or instability of contract 6
Contractor entitlement in kind 3
Table 25: The four primary themes within disadvantages of PSAs for O&G, and the frequency with
which they appear
Highly Complex Contract
This theme is split into three concepts and the most frequently mentioned was
the PSA being “less transparent” and “nebulous”. It is more open to interpretation
than a CA regime and harder to understand, for both the users of the contract and
the shareholders in the O&G companies. It is more difficult to negotiate and
navigate legally should the need arise. This is not surprising as the PSA offers a
partnership between counterparties, unlike a CA. A company, or a government,
party to several PSAs in a country must understand each. In a CA regime, both the
Contractor and Government would only have to be experts in that one regime.
The second angle is that the contract is complex to understand; making it
challenging to administrate the activities, to model financially for decision-making,
and to complete the accounting after the fact. Participants with experience as
accountants and financial modellers in both PSAs and CAs made similar comments.
The final observation is that PSAs create more work for the Contractor and are
tough to administrate and remain in compliance with, as they contain many
requirements to fulfil. Local content, education and training, infrastructure building,
and knowledge transfer all require effort and administration, plus extra work to
179
180
demonstrate compliance with the contract. The job of tracking expenditure for cost
recovery often falls to entire departments of an O&G company if that company
holds multiple contracts. Working alongside inexperienced staff seconded from the
NOC to the project and training them requires time and effort to be done properly.
Limited Contractor Upside
The flipside to the benefit for the host country of taking the bulk of the profit in
a highly lucrative project is that the Contractor’s profits are limited. The company
continues to get a portion of the profits as they rise, but the proportion often
becomes smaller and smaller. Consider the case of [country name redacted1], where
the Contractor takes 51% of the profit at low production rates or price levels but
takes only 10% of highly profitable projects (Wood Mackenzie). One participant
referred to the excess profits as “a buffer” for the Contractor in this context.
However, when describing the profit-sharing mechanism as an advantage to the
Government the profits had been described as “super-profits” and “excessive
returns”. It seems it is a matter of perspective, but perhaps it is not surprising that a
clear advantage for one party is seen as a disadvantage for the other. The
enthusiasm with which the participants spoke of the benefit for the Government
outweighed the slight resignation with which they spoke of the same characteristic
being a disadvantage for the Contractor, suggesting the structure is a good one. A
specific point made by one participant was that capping the upside might have the
effect of making the investor, the Contractor, more risk averse. Since O&G
exploration is an inherently financially risky business, this could lead investors to
181
look to explore in countries with a regime that allows the Contractor to capitalise on
the financial upside as a reward.
The other negative stance taken by the participants on the limiting of the
Contractor upside was the fact that Income Tax is paid out of the Profit Split
portion, if the company is in a taxable position. As previously mentioned, this
means that a nameplate 50% Profit Split can become significantly less if, on
average, 31% tax is levied.
Abuse or Instability of Contract
The participants highlighted a few ways in which the contract can be abused,
starting with the occasional propensity of unethical local officials to require that the
budgets for local improvements be spent on items that only benefit specific
individuals. An example given was a West African official who pushed for a villa in
France to be purchased from money earmarked for local improvements.
The second abuse lies with the Contractor, who may be inclined to “gold
plate” items of expenditure in order to recover more costs. The items would have
specifications that are higher than strictly necessary, but since those higher costs
can be recovered, the Contractor is ambivalent to the wasted expenditure, or can
even use the additional expense to increase project quality and profitability
(Johnston & Johnston).
The sanctity of the contract, which is not always honoured, was the final point
raised. Two participants indicated that PSAs are often in countries where the rule of
law is less developed, so there may be a higher risk than in OECD countries of the
182
Government reneging on or changing the deal, or regulatory agencies or local
businesses not abiding by the contract.
Contractor Entitlement in Kind
This topic was a minor one but was raised by two participants on three
occasions. The O&G company’s financial statements can only reflect the resources
to which they are entitled in a PSA, and that is only a portion of the total resources.
Contrast that to a CA in which they can book all the resources in the O&G field, as
the Government does not retain ownership. One participant commented that this
issue is less important than in the past, but the booking of reserves to indicate the
size of the company is a big annual activity and is viewed critically by shareholders
(Researcher’s experience).
Participants’ Thoughts on Renewable Energy and the Transition
The interviews yielded two primary reasons for the change to renewable
energy, two sets of characteristics of the transition, and two unresolved talking
points, as shown in Table 26.

Talking Points 2
Table 26: The themes emerging from discussion of the transition to renewable energy
Commitment to the Environment
Participants talked of the transition in terms of the “energy mix” and “energy
matrix”, commenting that the transition, as the name implies, is a phasing out of
environmentally damaging energy sources and their replacement with less harmful
ones. One talked of an expansion – in the number of sources, and also an overall
expansion as energy demand grows. Another spoke of the clear necessity for the
transition, given climate science data. One talked of traditional O&G companies
committing to climate goals such as the Paris Accord and carbon neutrality which
seem in conflict with their core business. He said, “…the end game is not the
same … as … being a pure oil and gas company anymore… It's a lot about
sustainability, the environment, SSU, things like that”. Three participants expressed
positive views of OWE as a part of the new energy matrix, including “it’s a
wonderful, wonderful thing” and “offshore wind farms will definitely be a big part
of this mix”.
184
Despite being O&G workers, with over 200 years’ experience between them,
the participants have reasonable knowledge of, and a positive disposition towards,
the transition and OWE.
Socio-politics
Three participants mentioned political angles that drive the transition. The first
involves “telling people what they want to hear” – politicians speaking publicly of
the transition to gain popularity, then policy following the promises that have been
made. The others include energy security, diversity, equity, and affordability. These
topics were discussed earlier in Chapter 2. Renewable energy, including offshore
wind can improve a nation’s security and diversity of supply, can provide cheaper
energy sources, and can provide power where perhaps there was no access before.
Financial Outlook of the Transition
In terms of characteristics of the transition; costs, returns, and subsidies came
up frequently. Three participants cited the fact that most projects need subsidies and
one pointed out that subsidies can serve to obfuscate the true returns of the projects.
Four participants talked about the costs involved in building renewable energy
plants with a negative tone, but interestingly, two of them referred to the high cost
of leasing seabed for OWE projects, which itself implies competition. Willingness
to pay a large access cost implies the buyer sees the opportunity for financial return,
or else they would bid lower, or not bid at all, and pursue other lines of business.
Perhaps these companies see the falling costs of offshore wind, and the pressure for
transition, and are prepared to hold the land and wait until their project is
economically viable.
185
On the inferior returns, one participant said, “the returns are really
questionable, especially versus oil and gas projects” and another stated “it's
difficult to find profitable projects within the renewables space”. She went on to
admit that a lower rate of return is acceptable as the risks are less for renewables
than O&G. This acceptability is due to the renewable resources being demonstrable
ahead of time, whereas O&G is only proven after expensive operations, and
frequently with a chance of success of 10-30% (Brez-Rouzaut). She quantified this
comment on the rate of return: “… oil and gas projects, where you're looking at
maybe more than 20% returns. Now you're looking at sub 10 [%] for renewables
type projects”.
The fact that the participants have an understanding of the financial aspects of
the two energy sources qualifies them to discuss the application of the cash flow
split through Royalty, Cost Recovery, Profit Sharing, Uplift, and Tax in a PSA-like
instrument.
Timing and Pace of the Transition
None of the participants were in any doubt that the transition is here, though
opinions of the timing varied from “on a fast pace” and “here to stay” to “guilty of
being a little too optimistic about how fast we’re gonna get there”, “somewhat slow in
coming” and “a good fifty-plus years to go”. It was noted that the pace varies by
region – Europe being quicker to transition than the US.
One participant reminded us that this is not the first energy transition humanity
has been through, citing the transition from coal to oil - and this researcher notes there
have also been transitions from wood to coal even earlier, and from oil to gas more
186
recently. As outlined in the “Commitment to the Environment” section of this
chapter, this transition will take the form of a phasing down of hydrocarbons and
ramping up of renewables, potentially resulting in the elimination of fossil fuels, in
several decades.
Several factors were raised in the interviews that are slowing down the transition.
These include aging transmission grids or the inability of a grid to take additional
power, technology lagging behind the desire for clean power, and the supply of rare
earth metals.
A participant talked of the common misunderstanding among the general public,
perpetuated by their leaders, that “we can flip a switch … leave all that nasty oil in the
ground… and it’s rainbows and unicorns”. Without a clear common understanding of
the issues and goals, a successful transition will be delayed. One confounding concern
that is frequently raised, and was voiced by one participant, is that renewable energy is
not truly zero emissions once building, transporting, operating, and maintaining the
facilities is factored in. Using cost and risk as an argument against transition is
considered foolish by Toh, writing for the Columbia Climate School (2021) as the
costs of unabated climate change will be far higher.
Talking Points
The first unresolved talking point concerned intermittency which is a big
concern for renewables and is discussed briefly in Chapter 2 above. The second
relates to the environmental effects of renewable energies themselves; in this
instance, the harm that offshore wind turbines might do to the bird population.
There will no doubt be negative environmental effects from renewable energy, but
187
provided those effects are less than the harm caused by hydrocarbons, there is a net
step in the right direction.

Positive: Local Development
The local area benefits of using PSA-like terms for offshore wind fall into four
categories: education, training, local content, and infrastructure. Education includes
universities, which will provide the next generation of qualified staff to work on wind
farms. One participant makes the point that offshore wind will, by definition, be new
to any country without an OWF today and that providing education through the PSA
will be a benefit to the nation.
188
In terms of training, three participants saw an advantage in local workers
receiving the training they need through the PSA mechanism. The point was again
made about the OWF work being a new skill and tuition being required. Training
requirements in the PSA were seen by participants as “an attractive thing for the
Government”, “pretty popular”, and it was said that “the Government would definitely
like that aspect of it”.
Local content remarks included the potential participation of the NEC in the
project, which offers a route to learning, and a way to make a profit from an OWF.
One participant spoke of Petrobras, the Brazilian NOC, who is entering the OWE
business. This comment was verified in Memija’s (2023a) article announcing
Petrobras’s intended participation in 23 GW of OWFs. Other observations around
local content included the requirement to use local workers and facilities, thereby
developing the economy. The local workers will have been educated and trained due
to aforementioned PSA clauses.
It is probable that the local infrastructure will not yet be in place before the first
OWF is built - and that is the fourth element of local development. Three participants
suggested that the PSA could facilitate the building and maintenance of a grid that is
fit-for-purpose for the new supply from the OWF. One of those three made the point
that since the grid is built under a PSA, it belongs to the Government, which is
rightful since the country will need it for years to come, potentially long after the
Contractor has left. A second area of infrastructure arising in the interviews was port
amenities, needed for building and maintenance of offshore facilities. Again, the
comment was made that a country could be starting from scratch building
189
infrastructure for OWFs,
190
and a government would no doubt be happy to see those activities undertaken as part
of the PSA.
Overall, the remarks made on the benefits to the local economy and community
were broadly akin to those made when considering the advantages of PSAs to O&G.
Positive: Resource – Expertise Trade
One participant sees “the fit [to the PSA model] to be very good” in that “my
country has steady wind… my resource” and “you have the knowledge of how to build,
install and transmit the electricity”. Another cautioned that the wind resource would
have to be attractive enough to justify the complexity of the PSA – but as previously
discussed in this paper, there are plenty of excellent resources globally. A third
participant focussed on the advantages to the host country with no expertise. The “IOC
would have the operational knowledge… the host country would… sit back and reap
the rewards [from their resource]”.
Participants reminded us that expertise in OWFs is “new and upcoming” and
“knowledge …is …in its early stages” and it could benefit many countries if the
knowledge was transferred through a PSA-like mechanism.
NOCs, or NECs, also came up in the context of the trade, as a way to transfer the
expertise – “an important ingredient in … offshore wind”. Four participants opined
that some countries would like the opportunity to participate, for example, those with
immature NOCs, countries in Latin America, or Canada or Norway. Others such as
the USA were seen as less likely to be interested.
191
In summary, the participants saw the possibilities for PSA-like terms to provide
the same resource-expertise trade that PSAs provide for O&G.
Positive: Cost Recovery
Five participants identified the ability of the Contractor to recover costs through a
PSA-like mechanism as a positive, one calling it a “huge advantage”. To quote
another participant: “It's almost as expensive as developing an offshore oil [and] gas
project… and if you're allowed to, at the very minimum, recover your costs, I think
that would be helpful”. Risk reduction for the Contractor was mentioned several times
and two participants talked of the advantages of having a contract mechanism to
recover costs rather than just waiting for post-tax profit to outweigh investment made.
An interesting point that arose twice was that if the contract mimics a PSA
exactly, the Contractor would be awarded power in the way that it is awarded oil or
gas from a PSA in return for Cost Recovery and Profit Share oil/gas. In-depth
discussion did not ensue, and this is a point perhaps worthy of future research. Is there
any merit in the Contractor taking ownership of volumes of power which will be sold
into the local grid (export is unlikely), or should the transactions skip the resource
rights stage and be based solely on cash?
Much as PSA Cost Recovery is an advantage over other regimes in O&G, so
would it be for OWE, according to participants. Cost Recovery may perhaps be more
important for OWE, being a lower-margin business.
192
Positive: Cash Flow and Profit- Sharing
Participants saw the profit-sharing mechanism built into a PSA as a benefit for
OWE in two ways. The first is that the Contractor will have some assurance of a
return on an economic project through their profit share, taken after the costs have
been recovered. A second is that profit-sharing terms are progressive in nature and can
encourage marginal projects in a way that regressive terms such as royalties do not.
There was much discussion of profit-sharing in the context of O&G, and less
where OWE was concerned, perhaps because offshore wind is a low-margin business.
However, as renewable energy projects become more profitable, profit-sharing will
have increased utility.
Positive: Driving the Transition
One participant made the interesting point that the West is hypocritical in driving
the O&G industry throughout history, but now suggesting developing countries should
not enjoy the same level of economic development as we now know the dangers of
fossil fuels. He points out that through the PSA those countries can benefit directly
from the Western energy companies in terms of local development (as discussed
above), and this may hasten their transition.
Another thought-provoking issue raised is that developing countries using PSAs
for O&G will have familiarity and a comfort level with the contract and how it
functions. Using a similar contract may hasten their move towards OWE versus
another renewable energy with a steep learning curve attached.
193
The participants talked of mitigation of climate change as a key goal of the
energy transition and recognised that using PSA-like terms could assist.
Negative: Effect of Low Returns on Profit- Sharing
Five participants raised the issue of OWFs providing lower returns than the
“excessive returns” of a successful oil or gas field, and there being little revenue after
Cost Recovery to flow to Profit Share. One was concerned that the revenue may not
even provide for Cost Recovery, a matter that should be considered very carefully in
any investment decision, as it is for O&G projects. Another confirmed that the profit
share mechanism could work but would have to be adapted, as it is in every PSA, for
prevailing conditions. This researcher also believes that as the cost of OWE continues
to drop, a contract signed now that appears to have thin profit margins may indeed be
generating more cash than expected in two decades. Under these circumstances in the
hydrocarbon world, under a CA, the Contractor would take the upside. Under a PSA,
the host nation would enjoy the fruit of its resources. The same could be true for a
profitable future offshore wind enterprise under PSA-like terms.
A second observation was that the cash flow from the project may not sustain a
high degree of spending on non-financial benefits such as training, education, and
local content. This is another area that must be carefully considered in setting up and
negotiating a contract.
This concern for the application of profit-sharing ties to the participants’ concerns
about the financial outlook and current low returns of renewable energy projects.
194
Negative: Ability to Deliver Power Supply
Two concerns raised about the fit of offshore wind to PSA-like terms were the
ability to supply power per contract commitments, and the fact that power is not
currently exportable. The first concern will be greater when the time unit of
measurement of supply is small. If the Contractor is committed to supplying a certain
volume of power per second, or minute, and the wind is not blowing, the risk of
default is high. If the delivery is averaged over hours, days or a month, the risk
decreases. This would have to be carefully considered in the contract, in the absence
of an HRES.
The export concern is another area where the contract would differ from O&G.
Typically Contractors take their oil resource entitlement (barrels of oil equivalent to
Cost Recovery and Profit Share amounts), load it on tankers, and export it for sale.
Gas entitlement (cubic feet of gas equivalent to Cost Recovery and Profit Share
amounts) is often treated differently. It can be converted to liquified natural gas and
exported by a specialised tanker, or it may be sold locally into a pipeline network.
This latter solution informs the suggestion for power – sell locally into the grid.
Negative: Poor Fit to PSA Premise
The observations on this topic were twofold. One participant spoke of the risk
involved in offshore hydrocarbon exploration (and mentioned earlier in this paper) and
that the PSA is a good fit when large sums of risk capital are at stake. This participant
felt that there is less risk in building an OWF as the wind potential can be measured
prior to building. This is not to say a PSA cannot be used, but one of the motivations
for using it is absent.
195
The other question, raised three times, is whether the expertise to build an OWF
is as great as that needed to find hydrocarbons offshore. Participants questioned
whether the resource–expertise trade was as significant as in O&G. Neither the
researcher nor the participants are experts in OWFs and as such, may have a tendency
to underestimate the complexity of an area with which they are not familiar – the
Kruger-Dunning effect (Kruger & Dunning, 1999). It remains unknown from this
research whether an energy company is required to build an OWF or whether a
developing country government could achieve its installation. Given the big-name
energy companies that are the main players in the OWE industry, this researcher’s
suspicion is that those companies would have plenty of expertise to offer to merit the
use of a PSA.
Negative: Legal and Administrative Difficulties
This issue was only mentioned once, and mirrored comments made when
discussing O&G. All the identified negatives including complexity, lack of
transparency, and difficulty to negotiate and administrate, could apply equally to
OWE.
Opinions by Company Type
This researcher considers that analysing business opinions such as these by
demographic - gender, race, age, or income level – is unlikely to provide useful
insights. More curious is whether there are differences by company type:
consultant, IOC, or NOC. The total number of opinions given by the seven
participants on the advantages and disadvantages of PSAs in O&G and the positives
and negatives of PSAs for OWE was 228. These were split 48% by industry

consultants (of which there were three), 29% by IOC employees (of which there
were two), and 22% by NOCs (of which there were two). Given the small sample
size, the data were normalised by the number of participants. The consultants were
still the most talkative group, followed by IOC employees, then NOC workers, as
can be seen in Figure 24. It is true that the two NOC employees have English as
their second language, but the Norwegian, who has never lived in the USA, made
more comments than the Malaysian-American, who has lived in English-speaking
countries since adulthood. Language may affect the results, but this researcher
thinks it is more likely due to the fact that consultants are typically expected to
spend more time expressing their opinions than internal O&G company economists
(as are both NOC employees).

197
When talking about the positives that PSAs could bring to OWE, the
participants were split fairly evenly across the company type at 31% NOC to 36%
IOC to 33% consultants. Similarly, when opining on the advantages of PSAs in
O&G, the split was fairly even at 29% NOC, 39% IOC, and 35% consultants. NOC
employees saw advantages of PSAs in O&G less than IOCs did, which is an
interesting result, as NOC employees may be more likely to view PSAs from the
Government’s perspective. Governments tend to like PSAs due to the option to
participate whereas energy companies can be put off by the potential interference in
daily operations (Kiyayi). It could be because the NOC participants in this research
work for a company that behaves like an IOC and does not enter PSAs on the side
of the Government but on the side of the IOC.
When it comes to the negatives, consultants came to the fore. Regarding both
the disadvantages of PSAs in O&G and the negatives of PSAs in OWE, consultants
voiced over half the opinions (53% for both). This researcher can only speculate at
why this is, but perhaps it has to do with consultants being career problem-solvers,
and identifying negatives may come naturally and foremost to them. An implication
is that if this concept – PSA-like terms in OWE – is to be introduced to potential
users, it should be demonstrated to the IOCs and NOCs (and governments) directly.
It should not be introduced through consultants who might portray it negatively.
Had government or energy ministry employees been included in the study,
these results might have been different. It is possible they would have seen more
positives of PSAs. This is analysis that could be undertaken in future if the
participant sample is expanded.
198
CHAPTER 5
DISCUSSION
This study is timely as the effects of climate change and the importance of efforts
to mitigate it are widely and frequently publicised. The research takes an O&G best
practice – the PSA - and applies it to OWE. This provides an additional option for the
contract governing the leasing of seabed for OWFs over and above the contracts used
today in the few countries with offshore wind. It also further expands the list of the
O&G practices being harnessed by offshore wind as discussed in “Learning from the
Oil and Gas Industry” in Chapter 2.
The research is aimed primarily at developing countries which have OWE
resources but no OWFs. Offshore wind was not an accessible solution for such
countries when it was a high-cost energy source and needed government subsidisation.
The path may not be smooth or linear but OWE costs are lower, competitive, and
continuing to fall, and the days of subsidisation are passing or over (Jansen et al,
2022). Developing countries are starting to take an interest in OWE, including
Vietnam, India, Brazil (discussed in Chapter 2), Sri Lanka (Boopathi et al, 2023,
Economynext, 2023), Bangladesh (Garg, 2023), and Colombia (Anchustegui, 2023;
Emmanuel). Of these countries, all but Colombia use PSAs and enjoy the benefits
identified in the qualitative research.
This convergent mixed method research was conducted in two parallel phases and
found that PSA-like terms could successfully be applied to OWE. Success is defined
quantitatively by project economic viability and qualitatively by the provision of
benefits to the parties to the agreement.
199
Economic Viability and Optimal Contract Terms
It was concluded that under the contract terms, discount rates, generation, price,
and cost conditions used in this research, PSA-like terms can be used as a leasing
instrument for acreage on which to site an OWF. Pursuant to T-tests, the null
hypotheses associated with H1-1 and H1-2 were rejected and both Government and
Contractor mean NPVs are statistically greater than zero (RQ1). Since both
contracting parties will realise a positive NPV they should rationally be willing to
move forward with the project, in the absence of a better project competing for
financial or human capital. This research is the first to apply the terms to OWE and is
also unusual in considering both the Contractor and Government outcomes in the
meta-modelling of a PSA.
The sensitivity of the NPVs to the fiscal terms was assessed broadly through
multiple regression and the models yielded good explanatory power with R2 of 84%
(Contractor) and 90% (Government) (RQ2 and 3). The null hypotheses associated
with hypotheses 2-1-1 through 2-2-5 and 3-1-1 through 3-2-2 were rejected following
the multiple regression analysis. The contract terms associated with those hypotheses:
Royalty, CRC, CPS, Uplift Rate, Discount Rate, Tax Rate, Average Price, and
Average Generation all have a significant effect on NPV.
Using scenario analysis, the behaviour of the five fiscal contract term IVs was
studied, and various idiosyncrasies uncovered. Further, the sensitivity of each term
within a small range was tested using the same technique, which would be useful
during negotiation to uncover the optimal set of terms (RQ4). A user of the model can
elect to constrain variables to small ranges or allow the model to draw from the full
200
distribution. For example, the user could study a small range of fiscal terms in
combination with the full distribution of Price and Generation data, which has utility
in real-world negotiations. This research found that the total NPV is somewhat
insensitive to changes in Price, Cost, and Generation, but a successful project outcome
(positive NPVs for both contract parties) is more sensitive to changes in those IVs
(RQ5). This is important information when selecting a site for an OWF and designing
the turbines and their placement. Further, knowing the sensitivity of project
economics to Price is helpful in deciding whether to seek a PPA which locks in the
power sales price. This long-term price guarantee is not something available for oil
production.
Multiple regression and stochastic scenario analysis are advanced techniques and
could complement the single-point NPVs and deterministic scenario analysis often
seen in the O&G industry. It would be interesting in the future to perform the same
analyses for an oil or gas field, and the conclusions would have utility for Contractors
or Governments negotiating O&G leases. The cash flow model can be adapted to
such that the technical inputs can be specific to a certain oil or gas field and the terms
represent a specific PSA.
Other future directions for this quantitative research include studying other more
minor fiscal terms found in PSAs. These will have less impact on NPV but
nonetheless exist in O&G and may have utility in OWE. Likewise, the dependent
variable list could be increased to include more economic indicators, such as IRR and
Contractor and Government Take, as studied by KP, and profitability indicators,
popularly calculated in the industry.

Advantages and Disadvantages of PSAs in O&G and Applicability to OWE
Many of the themes arising from the interviews were common to both O&G and
OWE discussions. Figure 25 shows the three themes that are common among the
advantages, and the three O&G themes and one offshore wind theme that are not
common.
202
Figure 25: The common and unique themes when comparing PSA advantages across O&G and OWE
203
The non-financial benefits of PSAs; the education, training, jobs, infrastructure,
and participation of the NOC in the project were seen as important in O&G and of
great potential benefit for OWE if the project economics can sustain the expense.
Focussing briefly on the last, NOCs, Strambo et al (2023) studied four Latin
American NOCs for their strategic direction with regards to climate change and found
challenges. The authors point to the existential threat to NOCs who focus solely on
hydrocarbons as the world transitions to renewables. They also point to the immense
opportunity NOCs have to drive change, as they own 58-66% of the world’s
hydrocarbons, but identify two challenges that they face. Those are limited capacity
for change and institutional barriers. Should OWE come with all the above-mentioned
advantages, perhaps it would be easier for NOCs to change strategy and protect their
very existence.
Cost recovery, viewed as a tremendous and unique feature of the PSA, could
have even greater importance in expensive OWE projects with low returns. Profit-
sharing is also perceived as an excellent contract term in O&G due to its progressive
nature and ability to reward the resource owner in highly profitable projects. This too
has application to OWE especially as projects are likely to become more profitable in
the future. Governments who establish a limited share of an OWF profit today,
thinking that profits will be low, may regret that decision in the future if profits rise
and all flow to the Contractor.
The trade of expertise for resources and the knowledge transfer that comes with
the PSA structure and the relationships it governs works very well in O&G and is
similarly applicable to OWE.
204
The three O&G themes not raised in the OWE discussion could still have
applicability – if the contract was structured comparably. The host would retain
ownership of the resources, would have low-cost, low-risk participation, and the PSA
would be an enduring contract between the parties. Perhaps given more interviews
these would also have been identified as OWE themes. The last unique theme, driving
the transition, is clearly unique to OWE.
Similarly, there was commonality among the disadvantages of PSAs across O&G
and OWE, shown in Figure 26. Two themes were in common, and each of O&G and
OWE had two unique themes.
205
Figure 26: The common and unique themes when comparing PSA disadvantages across O&G and
OWE
The difficulty associated with PSAs being complex to understand and administer
in O&G would clearly be relevant to OWE and was identified as such. The limitation
of Contractor upside in O&G is not the same issue as the ineffectiveness of profit-
sharing in low-return environments but affects the same fiscal term. In O&G the issue
was felt to be the capping of upside in highly profitable projects and the awarding of
the majority of the profits to the Government. However, low-profit projects can occur
in either O&G or OWE, then the point made about OWE - that there is little profit to
206
be shared – is equally relevant. However, the opinions of the participants about the
flexibility of profit-sharing and its progressive nature are applicable regardless of the
energy source. In the future, as costs fall further, OWFs could be characterised by a
wide range of profitability, and then PSA-like profit-sharing would offer the same
flexibility that it does in O&G.
O&G’s first unique theme - abuse or instability of contract - could equally be a
disadvantage to OWE but was not mentioned in the interviews. The second –
Contractor entitlement in kind – is a moot point. The Contractor is unlikely to want to
export power, as previously discussed, but the contract could allow for this should it
wish to.
OWE’s first unique disadvantage – the poor fit of a few PSA terms to some
facets of offshore wind – is applicable only in that arena. The second – the ability to
deliver power supply – is certainly an issue in a one-source power generation system
but could be mitigated, as argued elsewhere in this paper, by an HRES or by carefully
selecting the periodicity of measurement of supply.
In summary, the participants found many positives about the use of PSAs for
O&G, in fact, positive references outweighed negatives 56 to 18. Many of these
positives can also make a PSA-like contract appropriate for OWE. Of the negatives
about PSAs in O&G, most would also be disadvantages for PSA-like terms in OWE.
The PSA for offshore wind would have to be carefully crafted to take into account the
differences between the two energy sources, such as today’s low-profit margins of
wind and the fact all the power generation is likely to be supplied to the local grid.
207
Future research should look in more detail at specific PSA terms and how they
should be adapted. Open questions following the interviews may also produce
valuable future research. These included periodicity of supply commitment and
intermittency issues, Contractor entitlement to power or cash, rights to sell into the
local grid, and whether a discounted DMO for the host country is appropriate or
feasible in a low-margin business.
Further, expanding the sample and conducting more interviews, and
incorporating Government or energy Ministry employees would be worthwhile - given
the significant time needed to obtain IRB approval for non-USA participants.
Conclusion
PSA-like contract terms could be applied to a profit-making OWF and provide
another style of lease contract between OWF developers and the resource owner.
The contract fiscal terms can fit an OWF in multiple ways. The lower Royalty found
in a PSA versus a CA regime can encourage marginal projects better than a high
Royalty. Early OWFs without subsidisation may suffer marginal returns. The Cost
Recovery mechanism can encourage Contractors to take the risk of leasing seabed
and building OWFs. The profit-sharing mechanism, as in O&G, can allow the
Contractor a reasonable rate of return but award the bulk of the excess cash flow in a
profitable project to the resource owner, the Government. Even if the Contractor is
not in a taxable position in the country and will pay no tax, the Government will
benefit from profit-sharing. As the PSA is a contract, and not a regime covering all
offshore wind activities in a given country, the details of the Profit Split can be
tailored to the individual project or area. The Uplift mechanism can be employed
much as it is in
208
O&G for new technologies and new areas. The new technology here is offshore wind
and the new geography is developing countries.
The non-financial terms of the contract will benefit the local economy which will
see regional industry and infrastructure developed and jobs created. The Contractor
will benefit from the improvements they make to the infrastructure that they need for
the project. Finally, the Government may participate in the project, setting up an NEC,
and learning to maintain the project or build new ones after the Contractor has moved
on. With these advantages available, a developing country using PSAs for O&G may
find the switch to OWE attractive and may even be willing to forgo some hydrocarbon
development for advances in a cleaner energy source. Since no developing countries
except Vietnam have any offshore wind capacity and few others are in the planning
phase, the timing is right to introduce a new contract type.
In order to use a PSA-like contract, a government would need to design the
detailed terms and offer acreage to the industry under this new contract. Bidding for,
or direct negotiation of, the terms could ensue, and the Government would partner
with its preferred candidate and sign the contract. The Government should be mindful
of the negatives associated with the contract, such as complexity, and design it
carefully. The cash flow model used in this research could assist both parties with
negotiation and planning.
Namibia would be an interesting candidate for this new contract type. As stated
before, the country imports almost all the power it requires (Choti & Xydis). It does
not have O&G production off its shores but had its first oil discovery in 2023 (S&P
Global, 2023) and expects first oil production in 2030 (Roelf, 2023). A transition to
energy independence not through oil but through offshore wind would be less
damaging to the climate, and Namibia’s wind potential is among the best (Figure 1 &
Figure 2).
Future research on this topic could expand the PSA-like contract to other sources
of renewable energy. Other research could analyse the situation and applicability in
specific developing countries, knowing the wind potential, likely costs, market, and
grid availability, infrastructure situation, and the terms currently in use in their PSAs
in O&G.
Finally, since PSA stands for Production Sharing Agreement, and this new
contract will neither have production (refers to O&G) nor the in-kind entitlement
clause which awards the Contractor barrels of oil or cubic feet of gas, a new name is
proposed by this researcher: “Offshore Wind Acreage Usage Agreement”.
