The largest combined solar and energy-storage project in the U.S. is now online and operating in California’s Mojave Desert.

The sprawling megaproject stretches across 4,600 acres in Kern County and is located on private land as well as the Edwards Air Force Base. It’s the biggest public-private partnership the U.S. Air Force has ever been involved in.

Known as the Edwards & Sanborn project, it was developed by Terra-Gen and built by Mortenson, an engineering, procurement and construction (EPC) contractor. Construction started in the first quarter of 2021 and completion was announced last week. The project includes an astonishing 1.9 million modules from panel-maker First Solar, and 120,720 batteries from LG Chem, Samsung and BYD — which makes it the largest such project in the U.S., according to Mortenson. The equipment is connected with more than 400 miles of wire, according to Brent Bergland, Mortenson’s VP of project development.
