Terra-Gen and Mortenson have substantially completed the Edwards & Sanborn Solar + Energy Storage project, the largest solar + storage project in the United States. Mortenson was the full engineering, procurement and construction (EPC) contractor on both the solar and energy storage scopes.
This project stretches over 4,600 acres and includes more than 1.9 million First Solar modules. In total, the project generates 875 MW<sub>DC</sub> of solar energy and has 3,287 MWh of energy storage with a total interconnection capacity of 1,300 MW.

The project supplies power to the city of San Jose, Southern California Edison, Pacific Gas & Electric Co. and the Clean Power Alliance and Starbucks, among others. A portion of the project is situated on the Edwards Air Force Base and was the largest public-private collaboration in U.S. Department of Defense history. The project uses LG Chem, Samsung, and BYD batteries.
“Now fully operational, this facility is a transformational project in the industry and is providing resiliency to the grid,” said Brian Gorda, VP of engineering at Terra-Gen. “The Mortenson team was tasked with an extremely difficult goal to build this project, and they proved to be the right partner for the job. We are excited to bring Edwards & Sanborn online and benefitting the people of California.”
In total, more than 1,000 craftworkers contributed to the project with more than 1 million hours of injury-free labor and a safety award by the California Association of General Contractors.
“Mortenson is honored to help Terra-Gen deliver the Edwards & Sanborn project and provide the region with clean, resilient power,” said Mark Donahue, senior VP at Mortenson. “I’m proud of the world-class facility our team designed, built and commissioned for Terra-Gen.”
