Battery Storage Will Replace Traditional Power Distribution System in Rural Arizona

While the community of rural Arizona’s Punkin Center is constantly growing, the local electric company Arizona Public Service (APS) needs to extend the region’s electric supply system.

For this purpose the company announced this week to have decided to install two 4 MWh batteries instead of renewing and extending the traditional power distribution infrastructure. APS claims this project to be the first in the U.S. in replacing a region’s power supply by a large-scale battery system. The batteries will be delivered by AES Energy Storage. The implementation will start in the fall of 2017.

Scott Bordenkircher, APS’s Director of Transmission and Distribution Technology Innovation and Integration, explains that the installation of an energy storage system will cost no more than the reconstruction of the existing grid and will also be more reasonable in the long term: “We are watching as the prices come down on battery technology. Thoughtful implementation of battery storage is key to its future success. For a community like Punkin Center, the rural location, reduced implementation costs and added technological benefits make it the perfect candidate for this technology.”

The newly installed battery system is planned to not only store energy for the use in times of peak demand, but also to serve as the primary source of energy supply for a community of 600 residents.
