World's largest battery storage system installed in California

The largest battery energy storage project in the world, the 250 MW Gateway Energy Storage project, was unveiled in San Diego County, Calif., on Aug. 19.

The project will enhance grid reliability and reduce customer energy costs in the area and was installed by LS Power in the East Otay Mesa community.

The project replaces the previous LS Power battery project, Vista Energy Storage, which was installed in Vista, Calif., in 2018 with a capacity of 40 MW, as the largest battery storage system in the United States.

“Gateway and LS Power's other California-based energy projects will support the state in its clean energy and storage goals,” John King, LS Power’s Head of Renewables, said in a statement. “LS Power is a first mover in commercializing new technologies and developing new markets. By charging during solar production or off-peak hours and delivering energy to the grid during times of peak demand for power, our battery storage projects improve electric reliability, reduce costs and help our state meet its climate objectives.”
