Utility Procures New Energy Storage for Two Arizona Communities

Phoenix-based utility Arizona Public Service (APS) on Dec. 8 said it is bringing battery-based energy storage to the Arizona desert through a 4-MW energy storage agreement with AES Energy Storage.

A pair of 2-MW AES Advancion energy storage arrays will be deployed as part of the APS Solar Partner Program (SPP) and represent AES’ first installation in Arizona, the utility said.

“The best renewable energy is the type a customer never thinks about,” Scott Bordenkircher, APS’s director of technology innovation, said in a statement. “A light goes on, a load of towels gets washed and life goes on as reliably as ever before, all powered by the sun. This is the future APS looks toward as it studies energy storage.”

The two Advancion arrays will be installed in Surprise and Buckeye, according to APS. Installation of the arrays began in November 2016, and they are expected to become operational early next year.

“Energy storage offers APS a powerful, flexible tool for their network as they procure more of their energy from renewable sources,” AES Energy Storage president John Zahurancik said.
