Recurrent Energy, a subsidiary of Canadian Solar Inc. and a global leader in solar and energy storage development, has announced the successful commissioning of the 1,200 MWh Papago Storage facility in Maricopa County, Arizona. The project is now delivering stored electricity to Arizona Public Service (APS), the state’s largest electric utility, strengthening grid reliability just in time for peak summer demand.
Papago Storage is the first of three Recurrent Energy projects under long-term tolling agreements with APS to reach commercial operation. Combined, the three projects will provide 1,800 MWh of battery energy storage and 150 MWac of solar generation, delivering enough stored electricity to power approximately 72,000 homes for four hours and solar energy sufficient to support around 24,000 homes annually.
Derek Seaman, APS Director of Resource Acquisition, said, “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.”
Kevin Thompson, Chair of the Arizona Corporation Commission noted, “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.”
Arizona House Majority Leader Michael Carbone added, “I congratulate Recurrent Energy on this tremendous energy storage achievement. With our favorable 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.”
Beyond improving grid performance, the project brings tangible local benefits. Through its Community CaRE (Community and Renewable Energy) initiative, Recurrent Energy has made contributions to the Harquahala Fire District and Arlington Elementary School, supporting both public safety and education.
Canadian Solar’s majority-owned subsidiary, e-STORAGE, served as the project’s turnkey EPC (engineering, procurement, and construction) partner and will continue operations and maintenance under a long-term service agreement.
Ismael Guerrero, CEO of Recurrent Energy, stated, “The commissioning of Papago Storage marks a major milestone in our collaboration with APS to strengthen Arizona’s energy infrastructure. We’re proud to deliver flexible capacity that meets the state’s growing energy needs and grateful for APS’s continued partnership. As we begin operations, we remain committed to building long-term value for the local community and our partners.”
