Renewable energy provider Terra-Gen said it completed financing on the second phase of its Edwards Sanborn solar battery storage facility in Kern County, California. When complete, the facility is expected to be the world’s largest integrated solar-powered battery storage project, it said.
The second phase of the facility is composed of 410 MWac of nameplate solar capacity (358 MWac at the point of interconnection) and 1,786 MWh of battery storage.
The first phase of the Edwards Sanborn project was financed in July 2021 and its 345 MW of PV and 1,505 MWh of storage are now fully operational, it added.
The financing for the second phase includes $959 million of senior secured credit facilities.
The project is located on land leased from Edwards Air Force Base and adjacent private land. Mortenson is the full engineering, procurement and construction contractor on both the solar and energy storage. LG Chem, Samsung and BYD are supplying the batteries. The project at its peak employed more than 750 union workers on-site.
Terra-Gen expects the battery storage to be fully operational by the third quarter of 2023. It said it is advancing development on future phases of this project that will include over 2,000 MW of incremental solar and energy storage to be interconnected to the CAISO grid.
Subsequent phases will begin to be financed in 2023 and will start to come on-line in 2024.
Terra-Gen owns approximately 3.3 GW and 3,800 MWh of wind, solar and energy storage capacity in operation and construction across 28 renewable power facilities throughout the US.
