Strata Clean Energy Enters into 20-Year Tolling Agreement with Arizona Public Service for 400 MWh White Tank Energy Storage Project

Durham, NC – November 12, 2024 – Strata Clean Energy is excited to announce a 20-year tolling agreement with Arizona Public Service (APS) for the 100 MW/400 MWh White Tank Energy Storage project, located near Avondale in Maricopa County, AZ. The project is anticipated to be completed and integrated into the APS energy grid in April 2027.

This latest agreement underscores Strata's commitment to expanding its 7 GWh storage pipeline in Arizona, with over 1.6 GWh of storage currently under construction. These initiatives reflect a company strategy aimed at enhancing clean energy solutions to meet the significant and growing energy demands in the region.

“Strata has a pipeline of clean energy projects across the United States that provide effective solutions for power companies to strengthen the grid,” said Tiago Sabino Dias, Chief Development Officer at Strata Clean Energy. “Our experience in developing projects like White Tank enables us to support utilities like APS in reaching their energy goals.” 

“Strata has been committed to investing in Arizona for the past five years as part of our growth strategy to develop high-quality utility-scale projects in the region,” said Markus Wilhem, CEO of Strata. “Our strong partnership with APS, combined with the expertise of our Scottsdale team, is essential in executing this strategy.”

Under the new tolling agreement, APS will have the flexibility to charge and discharge the system as needed, while Strata will ensure the system's capacity, reliability, and efficiency throughout the duration of the agreement.

In June 2023, APS, Arizona's largest electric company, issued an All-Source Request for Proposal (RFP) to procure approximately 1 GW of resources, including 700 MW of renewable energy, in line with its Integrated Resource Plan. As part of the RFP, the White Tank Energy Storage project was awarded this contract, joining Strata’s Justice Energy Storage Project, which was awarded a contract earlier this year.

“During periods of the day when energy demand is highest, APS customers benefit from flexible resources that can quickly serve them with reliable electricity,” said Brian Cole, APS Vice President of Resource Management. “The White Tank Energy Storage project will help increase our growing portfolio of innovative energy storage technologies. Resources like this store electricity generated when solar power is abundant. APS operators can later release it to our smart grid to meet customers’ needs when the sun is setting and energy usage increases.”
