Out in the fertile yet water-constrained farmlands of California’s western Central Valley, a massive solar, battery, and power grid project that could provide a quarter of the state’s clean energy needs by 2035 has taken a critical step forward. In December, the board of directors of the Westlands Water District, the agency that manages water delivery to more than 600,000 acres in California’s agricultural heartland, approved the Valley Clean Infrastructure Plan. VCIP calls for building up to 21 gigawatts of solar energy and an equivalent amount of battery storage across up to 136,000 acres, along with a series of high-voltage transmission lines to connect the electricity generated to the state’s grid.
