Generators can be off during daytime
– 6 generator system (1.2 MW each)
– 1 generator equivalent required as operating reserve at all times
– All generators that are on typically operate at same level
– BESS removes need for operating capacity
– BESS can also delay or remove need to start up a generator during short term peaks
– Solar PV size limited in this case due to generator ramping limitation
– Additional generators must stay online in case of shading for 75% of solar production (potential reductions when using advanced forecasting)
– BESS provides required ramping
– During daylight hours all generators can be shut down completely

Assumptions: Delivered Fuel Cost: $1US/l; Solar installed cost: $2US/Wp; Average cost of capital: 11%; Subsidies: none
Up to 28% reduction in fuel and CO2 possible when combining diesel with BESS and solar PV
