ENERGY STORAGE IN CALIFORNIA
Double Butte energy storage project
AES’ Double Butte storage project is a proposed battery energy storage facility in Menifee, California that will provide a critical, cost-effective source of reliable power for the region’s electric grid.
Energy storage enables power generated during the day to be stored and delivered during periods of high demand, which helps stabilize the grid and reduce California’s reliance on fossil fuels. By delivering stored power when it is most needed, the Double Butte storage system will be critical to accelerating California’s transition to achieving 100% carbon-free energy by 2045.
