Pacific Gas and Electric Company (PG&E) held an official grand commissioning ceremony of its new battery energy storage system (BESS) - the Elkhorn Battery, located at its Moss Landing electric substation in Monterey County, California.
The Elkhorn Battery consists of a total of 256 Tesla Megapacks (roughly 3 MWh each), installed on 33 concrete slabs. The total energy capacity is 730 MWh, while power output is up to 182.5 MW, available for up to four hours during periods of high demand. With such specs, it's one of the largest BESS in the world.
