Terra-Gen Commissions 80 MW Lockhart IV Solar Project, Completes 365 MW Solar and 173.7 MW Storage Complex in California

Terra-Gen, one of the largest independent integrated renewable energy producers in the United States, has announced the commercial operation of its 80 MW Lockhart Solar PV IV project in San Bernardino County, California, completing the four-phase Lockhart Solar and Storage complex.

The newly commissioned solar project expands Terra-Gen’s renewable energy portfolio in California and is expected to generate enough electricity to power approximately 40,000 homes and businesses annually under a long-term power purchase agreement (PPA) with a California load-serving entity.

With the commissioning of Lockhart IV, the entire Lockhart Solar and Storage facility now has a combined capacity of 365 MW of solar generation and 173.7 MW of battery energy storage, capable of meeting the annual electricity requirements of more than 350,000 homes and businesses.

Commenting on the milestone, John O’Connor, Chief Executive Officer of Terra-Gen, said the commissioning of Lockhart IV reflects the company’s continued investment in projects that address rising electricity demand while delivering economic, social, and environmental benefits. He added that Terra-Gen’s development pipeline of more than 15 GW positions the company to continue deploying utility-scale renewable energy projects to support future energy needs.

Construction of the Lockhart IV project created more than 220 jobs at peak activity, with project teams completing over 122,000 work hours without any lost-time incidents. Cupertino Electric served as the engineering, procurement, and construction (EPC) contractor for the project.

Located across approximately 4,000 acres of privately owned land, the completed Lockhart Solar and Storage facility comprises nearly one million solar modules and 248 battery enclosures. The project is connected to the grid through the existing transmission line linked to Southern California Edison’s Kramer Junction Substation.

Terra-Gen is jointly owned by Masdar and Igneo Infrastructure Partners and continues to expand its renewable energy portfolio across the United States through utility-scale solar, wind, and energy storage projects.
