APS plans to add up to 2 GW of new gas generation to serve additional load in its Arizona service territory. The company announced up to $440 million to convert the retired Cholla power plant to 380 MW of natural-gas generation, with a new gas pipeline expected in service by late 2029. APS also increased its Palo Verde capital program by approximately $500 million over the next 10 years and acquired nearly 100 MW of nuclear capacity through a buyout option. These projects expand generation capacity to support reliability and customer growth.
