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.
