LS Power, an infrastructure investment manager and power generation developer announced today that it has energized its Gateway Energy Storage project in California. At anticipated capacity of 250 MW, the facility is the largest battery storage project in the world.

Located in San Diego County, Gateway Energy Storage is intended to provide much needed enhancements in grid reliability and reductions in customer energy costs. Californians have experienced frequent power outages this summer, as the state’s increasingly renewables-powered grid has often been unable to deliver energy at needed times. Increased battery storage could go a long way to solving the state’s energy issues.

LS Power CEO Paul Segal said:

“For more than three decades, LS Power has been at the leading edge of our nation’s transition to cleaner, more innovative energy solutions, and we are powering up Gateway Energy Storage as one more component of this vision. Through our investments in multiple sectors of the renewables and energy infrastructure space, LS Power is reducing carbon emissions and improving reliability in the markets we serve.”

LS Power has several other battery and storage projects in operation or in development in California and New York. The company’s Vista Energy Storage in Vista, California has been operational since 2018, and once held the title of largest battery storage project in the US. The company’s development and construction portfolio includes Diablo Energy Storage (200 MW) in Pittsburg, California; LeConte Energy Storage (125 MW) in Calexico, California; and Ravenswood Energy Storage (316 MW) in Queens, New York.

LS Power Head of Renewables John King said:

“Gateway and LS Power’s other California-based energy projects will support the state in its clean energy and storage goals. 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.”
