The United States’ largest solar and battery storage project has recently become operational in Kern County, California, reports Electrek. The Edwards & Sanborn project, developed and owned by Terra-Gen, spans 4,660 acres of Mojave desert land and comprises 875 megawatts of solar capacity along with 3,320 megawatt-hours of storage. It features nearly 2 million First Solar photovoltaic panels and over 120,000 batteries from LG Chem, Samsung, and BYD.

The enormous Edwards & Sanborn facility produces 875 megawatts of solar power and contains over 3,000 megawatt hours of stored energy, with a total capacity to provide 1,300 megawatts of electricity. It supplies renewable energy to the city of San Jose, utility providers, Starbucks, and other customers. Brian Gorda, a Terra-Gen vice president, stated the facility is “a transformational project in the industry and is providing resiliency to the grid.”

One Eletrek user wrote, “Very impressive.” Another commenter said the project represents about “the 40% mark” of progress toward ending California’s rolling blackouts.
