182.5 MW Tesla Megapack battery energy storage system (BESS) – known as the Elkhorn Battery – located at its Moss Landing electric substation in Monterey County. After final testing, the BESS was fully energized and certified for market participation by the California Independent System Operator on April 7, 2022.
BESS has the capacity to store and dispatch up to 730 megawatt hours of energy to the grid at a maximum rate of 182.5 MW for up to four hours during periods of high demand.

Water tank energy storage would be far safer. During hours of off-peak energy is used to to fill a water tank to capacity. During peak hours the water is allowed to flow to a second, lower tank through a hydroelectric generator. During off peak the water is pumped back up and the cycle repeats.
Or we could build a crap-ton of nuclear plants.
