Strata Clean Energy enters into 20-year battery storage fee agreement with Arizona Public Service

Once completed, the Justice Energy Storage project will have enough energy storage capacity to power approximately 24,000 homes for four hours. The project is scheduled for completion in April 2026 and will be connected to the APS power grid.

Last year, Strata entered into a similar 20-year tolling agreement for its 255 MW/1 GWh Scatter Wash battery storage complex, which began construction earlier this year. These partnerships between APS and Strata underscore the continued commitment of both organizations to delivering reliable power to a rapidly growing service area with increasing energy demand, while integrating more clean electricity into the region.

“We believe APS will continue to be a leader in battery energy storage, and our broad portfolio of clean energy projects, world-class execution capabilities, and our experienced team based in Scottsdale uniquely position Strata to help the region achieve its clean energy goals with projects like Justice,” said Josh Rogol, president of Strata Clean Energy.

Under the new tolling agreement, APS will be able to charge and discharge the system as needed. In return, Strata will ensure the system’s capacity, reliability and efficiency for the duration of the agreement.

“Our growing team in Arizona, combined with our national development platform and our internal EPC and O&M capabilities, allow us to develop projects with high certainty of execution for clients like APS,” added Tiago Sabino Dias, Chief Development Officer at Strata Clean Energy. “We are grateful for APS’s confidence in Strata and the well-managed process led by their resource team.”

“APS is carefully planning to meet Arizona’s growing energy needs with a diverse set of resources that will continue to serve customers with reliable, affordable, clean energy around the clock, especially during the summer months,” said Brian Cole, APS vice president of asset management. “Projects like Justice Energy Storage will benefit customers during the hottest times of day when they need power the most.”

In June 2023, Arizona Public Service (APS), the state’s largest and longest-serving utility, conducted an All-Source Request for Proposal (RFP) to acquire approximately 1 GW of resources, including 700 MW of renewable energy, to meet needs identified in the Integrated Resource Plan. Justice Energy Storage was among the projects awarded contracts as a result of the RFP.
