Overview
- Arizona Public Service says surging demand from data centers and AI is driving the need for new dispatchable generation.
- The Desert Sun Power Plant would add up to 2,000 megawatts, roughly a quarter of APS’s recent peak and enough to power about 300,000 homes.
- Construction is scheduled to start in 2028, with Phase 1 targeted to serve customers by late 2030 to backstop reliability when solar and wind are unavailable.
- APS plans a ‘growth pays for growth’ model in which large users sign long‑term contracts to fund Phase 2, a proposal that will undergo regulatory review.
- APS expects to source fuel from Texas via a planned 1,300‑mile Transwestern pipeline developed by Phillips 66 and Kinder Morgan from Borger to the Phoenix area.
