The 1.2GWh storage project is aimed to enhance grid reliability and support local community.
This facility is the first of three Recurrent Energy projects to begin operations under agreements with APS. Together, these projects will provide 1.8 gigawatt-hours of battery storage and 150 megawatts of solar power, sufficient to power approximately 72,000 homes for four hours or meet the annual energy needs of 24,000 homes with solar energy. The initiative enhances grid stability and supports Arizona’s growing energy requirements.
Derek Seaman, APS resource acquisition director, stated: “Summer is here, and we are ready to serve APS customers with the energy they need when they need it. The Papago storage project is part of our diverse and balanced energy mix, helping us continue to provide Arizona with top-tier reliability and affordable service.” The project also contributes to the local economy through job creation and infrastructure development.
Construction of the Papago Storage facility began in May 2024, with e-STORAGE, a majority-owned Canadian Solar subsidiary, handling engineering, procurement, and construction. e-STORAGE will continue to ensure the facility’s performance through a long-term service agreement.
Arizona House majority leader Michael Carbone commented: “I congratulate Recurrent Energy on this tremendous energy storage achievement. With our favourable business climate, Arizona’s economy is attracting development from all over the world, and we must provide the energy to accommodate this incredible growth. The Papago storage project will play an important role in Arizona’s energy future.” Arizona Corporation Commission chair Kevin Thompson added: “I commend Recurrent Energy for completion of their 300MW Papago energy storage project. Bringing online one of our state’s largest battery storage projects during this critical time when energy demand is growing rapidly will help our utilities execute an all-of-the-above response to that demand and further diversify Arizona’s energy resources.”
The Papago Storage project bolsters Arizona’s energy infrastructure, supports sustainable energy objectives, and fosters economic growth in Maricopa County.
