SRP Plans First Standalone Energy Storage Project

Salt River Project, a community-based, not-for-profit public power utility located in Arizona, has contracted with AES for SRP’s first standalone battery-based energy storage project. The 10 MW, four-hour duration energy storage solution, to be supplied by Fluence, will provide peaking capacity that will inject power into the grid during high peak demand periods for the utility’s customers.

The project is to be built in Chandler, Arizona.

“This latest investment will add needed much-needed efficiency and value for our more than 1 million electric consumers,” said Mike Hummel, SRP’s General Manager and Chief Executive Officer

Under the 20-year agreement, AES will provide SRP with the energy storage system that will be charged by an SRP distribution substation. Fluence’s Advancion energy storage technology platform was selected for use in the project.

SRP’s energy storage project comes at a time when Arizona is evaluating steps to transform its energy infrastructure, including proposals for both the largest energy storage target in the United States -- 3 GW by 2030 -- and a “clean peak” standard.

“AES is committed to developing solutions which will accelerate a cleaner and greener energy future,” said Ken Zagzebski, President of AES Southland Energy. “This project will allow SRP to continue meeting customer demands while also supporting the ongoing integration of renewable power sources.”

As the largest provider of power to the greater Phoenix area, SRP is drawing on both AES’ experience developing energy storage projects across its platform and Fluence’s expertise in designing and deploying energy storage solutions in 16 countries.

“We’re proud to support Salt River Project and AES in adding fast, flexible and zero-direct-emissions energy storage to SRP’s network,” said Stephen Coughlin, CEO of Fluence.

AES chose Mortenson as the EPC construction partner for the project. Mortenson has experience in the energy storage market and will be performing the engineering, procurement and construction for the plant portion of the project.
