| Generator for the Engineering Building | |
| Voltage | 480V/277V |
| Current | 1200A |
| Search for a backup generator that can be used in case of power loss | |
| Fuel Selection: | |
| Because the generator is not dedicated to run in permanent service, the price for the fuel has a minor relevance. | |
| Because Diesel (instead of gas) can be easily stocked in a tank for a long period of time we focused on diesel generators. Diesel is also not highly flammable which reduces the risk of fire. | |
| As well Diesel generators are cheaper and easier to maintain during service | |
| Due to the high amount of electricity needed solar panel would have been far too expensive. As well solar panels are only working during the day. | |
