Canadian Solar's 1200 MWh Arizona Storage Facility Now Operational

Canadian Solar Inc. has begun operations at its 1200 MWh Arizona storage facility. The company is a leading provider of solar technology and renewable energy solutions, with a diversified pipeline of utility-scale solar power and battery energy storage projects. Its Recurrent Energy segment is vertically integrated, offering expertise in greenfield origination, development, financing, and operations. CSI Solar consists of solar module and battery energy storage manufacturing, as well as total system solutions, including inverters and EPC services.

Canadian Solar Inc. has initiated operations at its 1,200 MWh Papago Storage facility in Maricopa County, Arizona. The project is the first of three Recurrent Energy projects with tolling agreements in place with Arizona Public Service (APS) to become operational. Collectively, these projects will provide 1,800 MWh of battery storage capacity and 150 MWac of solar generation [1].

The Papago Storage facility, which began dispatching stored energy to APS, is designed to meet the rising electricity demand during the summer season. Once all three projects are fully operational, they will store and deliver enough electricity to serve the equivalent of 72,000 homes for four hours, along with solar generation capacity sufficient to support approximately 24,000 homes annually [1].

Derek Seaman, APS Director of Resource Acquisition, noted that the facility is part of APS's diverse and balanced energy mix, contributing to top-tier reliability and affordable service [1]. Kevin Thompson, Chair of the Arizona Corporation Commission, commended Recurrent Energy for completing one of the state's largest battery storage projects, which will help utilities respond to growing energy demand [1]. Arizona House Majority Leader Michael Carbone also expressed his congratulations, highlighting the project's role in Arizona's energy future [1].

Canadian Solar's subsidiary, e-STORAGE, served as the turnkey engineering, procurement, and construction provider for the project and will continue to support Papago Storage under a long-term service agreement [1]. The facility's commissioning marks a significant milestone in Canadian Solar's collaboration with APS to strengthen Arizona's energy infrastructure [1].

Canadian Solar, headquartered in Kitchener, Ontario, is a leading manufacturer of solar photovoltaic modules, provider of solar energy and battery energy storage solutions, and developer, owner, and operator of utility-scale solar power and battery energy storage projects. The company has successfully delivered nearly 157 GW of premium-quality solar photovoltaic modules to customers worldwide [2].
