Kern County, California — State leaders gathered recently to mark the completion of the 105-megawatt Pastoria Solar Project, the largest renewable energy contract in the history of the California Department of Water Resources. Developed by Calpine, a unit of Constellation Energy, this sprawling 500-acre facility with 226,000 sun-tracking panels now feeds clean electricity directly into the grid supporting the State Water Project. The initiative stands as a critical step toward decarbonizing water delivery for 27 million residents and 750,000 acres of farmland across Southern California.[1][2]
A Bold Leap in Renewable Energy for Essential Infrastructure
Officials highlighted the project’s activation as a pivotal achievement during a ceremony on April 16, 2026, near the Tehachapi Mountains. Calpine completed construction ahead of schedule, with the solar array now operational and contributing to the grid.[3] This marks the single biggest renewable purchase by the Department of Water Resources, fulfilling part of its obligations under Senate Bill 100 for renewable procurement.[3]
The facility generates power specifically tailored to the demands of water infrastructure, rather than residential grids. Its proximity to high-energy pumping operations ensures efficient delivery. Karla Nemeth, director of the Department of Water Resources, emphasized the stakes: “Most Californians — the equivalent of one in 12 Americans — get water from the State Water Project. To make that system carbon neutral by 2035, we need efforts like the Pastoria Solar Project.”[1]
Prime Positioning at the Heart of Water Pumping Powerhouse
Situated just miles from the Edmonston Pumping Plant, the project targets one of California’s largest electricity consumers. The plant, operational for over 50 years, lifts water nearly 2,000 feet over the Tehachapi Mountains using up to 840 megawatts at peak — the world’s highest single-stage water lift.[2] Fourteen massive pumps in two wings draw from the state’s main grid to serve Southern California…
