Arizona Public Service Deploys BESS
Arizona Public Service (APS) signed an agreement for the 150-MW/600-MWh Justice Energy Storage project located near Skyline Regional Park in Phoenix, Arizona.
The utility company secured a 20-year tolling agreement with Strata Clean Energy for the project.
Once the project is completed, it will have the capacity to store enough energy to power approximately 24,000 homes over a four-hour period. The project is set to be completed 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 commenced construction earlier this year.
“APS is thoughtfully planning to meet Arizona’s increasing energy needs with a diverse mix of resources that will continue to serve customers with reliable, affordable, and clean power around-the-clock, especially during our summer months,” said Brian Cole, APS Vice President of Resource Management, in a statement. “Projects like Justice Energy Storage will benefit customers during some of the hottest parts of the day when they need electricity most.”
Under the new tolling agreement, APS will be able to charge and discharge the system for energy as needed. In return, Strata will ensure the system’s capacity, reliability and efficiency through the term of the agreement.
In June 2023, APS, the state's largest and longest-serving electric company, conducted an All-Source Request for Proposal (RFP) to procure approximately 1 GW of resources, including 700 MW of renewable energy, to address the needs outlined in its Integrated Resource Plan. Justice Energy Storage was among the projects awarded contracts resulting from the RFP.
