• The 125-MW facility will produce enough renewable electricity to power approximately 62,500 homes and businesses annually.

SAN DIEGO, May 20, 2026 /PRNewswire/ -- Terra-Gen, one of the largest independent, integrated renewable energy producers in the United States, jointly owned by Masdar and Igneo Infrastructure Partners, announced today that the Lockhart III solar project in San Bernardino County, California, has reached commercial operations.

"The expansion of the Lockhart project underscores Terra-Gen's commitment to continue developing clean, reliable energy resources critical to meeting the growing demand in California and nationwide," said John O'Connor, chief executive officer for Terra-Gen. "We are proud to bring more resources online that can help relieve strain and improve reliability across the electric grid to keep lights on at homes, and businesses and manufacturing running."

The 125-megawatt (MW) project utilizes the existing gen-tie line connecting to Southern California Edison's Kramer Junction Substation and will generate enough electricity to power the equivalent of approximately 62,500 homes and businesses annually.
