I was informed that a battery energy storage system can provide two time its nameplate capacity for regulation. Does this mean that if the three power supply system all have an available 40 MW for ancillary service, the battery can deliver twice as much as the pumped hydro and the gas turbine? Does this mean that the battery energy storage system should be paid double for its service?
Kindly compare the three in terms of being an ancillary service provider to the grid.
Thank you.
