Mokelumne Water Battery Project

The Mokelumne Water Battery Project is designed to reduce California’s reliance on fossil fuels by using excess renewable generation to pump water to higher elevations, storing carbon-free electricity until it is needed to meet peak energy demand.

The Project is located in the Sierra Nevada mountains, east of Sacramento, and about 33 miles east of Jackson, California.

When GreenGenStorage completes the Project, it will provide between 400 and 1200 megawatts (MW) of electricity, depending on the state’s energy needs, engineering design, and environmental considerations.
