Strata Clean Energy (Strata), a national leader in grid-scale clean energy solutions, celebrated the groundbreaking of the Justice Energy Storage facility in Maricopa County. The event brought together executives from Strata, Arizona Public Service (APS), and other local stakeholders. The 150 MW / 600 MWh project by Strata is expected to be operational in April 2026, delivering four hours of battery capacity that can power roughly 24,000 homes.
Once completed, Justice will play a critical role in strengthening Arizona’s grid reliability. It will assist in storing excess renewable energy generated during the day and dispatch it during peak evening demand—especially vital during Arizona’s extreme summer heatwaves.
“This project underscores our long-term commitment to enabling a resilient, decarbonized energy future,” said Tiago Sabino Dias, Chief Commercial Officer at Strata Clean Energy. “Justice will help Arizona move closer to its clean energy goals while supporting the economic vitality of the region.”
“At APS, we plan years in advance and maintain a balanced and diverse energy portfolio to serve our customers. With the addition of the Justice Energy Storage project, we’ll continue to deliver reliable and affordable energy as we power Arizona’s future growth,” said Brian Cole, APS Vice President of Resource Management.
Justice was awarded through APS’s All-Source RFP launched in June 2023 and is part of a 20-year tolling agreement between Strata and APS. Strata will develop, own, and operate the project as part of its portfolio of renewable and energy storage assets.
