On Aug 9, 2017, Arizona Public Service (APS) announced their plans to install two battery storage systems in rural Arizona, assumed to make it one of the first electricity companies to use batteries in place of traditional infrastructure.

According to APS, the two batteries are made by AES Energy Storage and construction is expected to begin in fall 2017.

Scott Bordenkircher, APS’s Director of Transmission and Distribution Technology Innovation and Integration, commented:

This project is a crucial step in the right direction for Arizona’s energy future. Over the next 15 years, APS has plans to add 500 megawatts of storage capacity. This project is indicative of the type of smart grid APS envisions for customers, one that enables people to have more technology in their own homes.

Per the company, batteries will be used to store excess solar power, storing energy and for other functions such as voltage support. The primary function of the battery is basic grid operation.

The pair of 4-MWh battery storage systems are expected to be operational in early 2018.
