California's solar surge outpaces natural gas in 2026

U.S. EIA data show CAISO utility-scale solar generated more electricity than natural gas on 82% of days from January to May 2026, with solar output up 21% vs 2024 and gas down 60%. Solar capacity reached about 25 GW and battery storage 16 GW, while natural gas capacity stayed around 29 GW. Despite a 7% rise in electricity demand, total CAISO net generation fell 19% as imports from hydropower and the new SunZia wind project in New Mexico offset domestic generation, and several capacity retirements occurred, including a 300 MW battery facility after a 2025 fire.

SunZia Wind Project Becomes America’s Largest Wind Farm, Supplying AZ and CA

New Mexico's SunZia Wind Project, the largest wind farm in the United States at 3,650 MW across 916 turbines, begins commercial operation and will export most power to Arizona and Southern California via a 550-mile HVDC transmission line, boosting New Mexico's total wind capacity to 7,647 MW (about 45% of the state’s mix). CAISO also reported a May 2026 wind-generation record as the project comes online.
