For many years now, OC San has been doing their job as a regional provider to help reduce the need to purchase energy from Southern California Edison’s (SCE) grid during critical times by having 4.9-megawatt(MW), 32-megawatt-hour (MWh) Tesla lithium-ion energy storage system at the Plant No. 1 in Fountain Valley, CA.

The Tesla storage system saves OC San ratepayers $300,000 annually and reduces the overall electrical needs during peak use periods so that other customers have greater access to the supply. This is in alignment with Governor Gavin Newsom’s initiative to reduce the need for energy from SCE grid during critical times.

The battery storage unit is one of the largest customer-sited battery system in the world.
