    APS Plans to Add Nearly 1GW of New Battery Storage and Solar Resources by 2025

    The Arizona power grid has a unique set of challenges, which it turns out solar and energy storage are particularly well suited to address. Arizona Public Service, the state’s largest investor-owned utility, announced Thursday morning that it will add 850 megawatts of battery storage and at least 100 megawatts of solar generation by 2025. That amounts to nearly 1 gigawatt of new clean energy technology, to be obtained through a combination of newly completed and upcoming procurements. The plan includes outfitting existing utility-owned solar projects with 200 megawatts of batteries, deploying 500 megawatts of new battery resources, and contracting for 150 megawatts of third party-owned storage — the last of which beat out new-build natural gas peakers in an request for proposals that just concluded.
