en.Wedoany.com Reported - The California Department of Water Resources, in partnership with developer Calpine, has successfully connected the 105 MW Pastoria Solar Project to the grid in the city of Arvin. This marks the largest renewable energy procurement in the history of the state's water project. Located near the Tehachapi Mountains in Kern County, the project has installed approximately 226,000 solar panels equipped with tracking technology, which enhances power generation efficiency by following the sun's path.
This solar project is dedicated to powering the Edmonston Pumping Plant, which lifts water nearly 2,000 feet over the mountains to supply the energy-intensive water demands of Southern California. The pumping plant is equipped with 14 large centrifugal pumps, each rated at 80,000 horsepower. A single motor-pump unit stands about 65 feet tall and weighs 420 tons. When all units are operational, the plant's electricity consumption can reach 840 MW, making it the largest single electricity user in California.
By securing a dedicated renewable energy supply, state officials aim to stabilize water supply costs and avoid impacts from energy market volatility. The current energy market is facing price pressures due to the expansion of artificial intelligence data centers. This project is a key component of the California Department of Water Resources' legally mandated goal to achieve carbon neutrality by 2035. The site operates as a multi-resource energy park, integrating the new solar capacity, an existing 750 MW natural gas facility, and an upcoming 80 MW battery storage system, the latter known as the Pastoria Energy Bank.
Labor representatives from the California Building and Construction Trades Council stated that the project utilized union labor, helping to align the state's climate goals with local economic development.
