Arizona's 1,200-MWh Papago Storage Project Commences Operations
LCG, July 7, 2025--Recurrent Energy, a subsidiary of Canadian Solar Inc., announced today that the 1,200 MWh Papago Storage facility in Maricopa County, Arizona, has achieved commercial operation. The project is now dispatching stored energy to Arizona Public Service (APS), the state's largest electric utility, in time to help meet rising electricity peak demands during the summer season.
Papago Storage is the first of three Recurrent Energy projects with tolling agreements in place with APS to become operational. The three projects together will provide 1,800 MWh of battery storage capacity and 150 MW of solar generation.
e-STORAGE, Canadian Solar's majority-owned subsidiary, was the turnkey engineering, procurement, and construction provider for the project and will continue to support Papago Storage under a long-term service agreement.
"The commissioning of Papago Storage marks a major milestone in our collaboration with APS to strengthen Arizona's energy infrastructure," said the CEO of Recurrent Energy. "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."
APS's 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."
The Chair of the Arizona Corporation Commission stated, "I commend Recurrent Energy for completion of their 300 MW 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."
In 2023, Recurrent Energy announced its 20-year tolling agreement with APS for the 1,200-MWh Papago Storage project, which was to be the largest standalone energy storage project in Arizona when it commenced operations in 2025.
Recurrent Energy later announced in October 2024 its two new, 20-year tolling agreements with APS for the Desert Bloom Storage and Papago Solar projects located in Maricopa County, Arizona. Desert Bloom Storage is a 600 MWh standalone storage facility, while Papago Solar is a 150 MW solar facility. Both projects are scheduled to achieve operation in 2026.
