Western Water and Agriculture

NPR reports that the Westlands Water District in California’s San Joaquin Valley is backing a proposal by developer Golden State Clean Energy to turn roughly 200 square miles of largely fallowed farmland into what would be the nation’s largest solar complex, capable of producing about 21,000 megawatts and paired with large batteries. Westlands farmers, long dependent on a federal canal and deep aquifer pumping, are losing irrigation supplies to drought, competing water demands, and a new state groundwater law that effectively bans chronic over‑pumping, forcing them to abandon sizeable acreage and seek alternative land uses. Some of the land in question is already permanently fallowed because irrigation there mobilizes toxic selenium, making it more suitable for solar panels than crops. Developer Patrick Mealoy says the sheer scale is deliberate: only a cluster of very large projects can economically justify the multi‑billion‑dollar high‑voltage lines needed to carry power from the valley to demand centers like Los Angeles and Silicon Valley, a bottleneck that has stalled many smaller proposals. The effort highlights how climate change, water scarcity and grid‑transmission constraints are pushing one of America’s most productive farm regions toward a new role as a solar‑energy hub, raising wider questions about food production, rural economies and who pays for the transmission build‑out.
