Battery power backs up New York power grid

AES Energy Storage is building a 20 MW battery powered system to provide reserve capacity to New York State's power grid.

Batteries power everything from pacemakers to smartphones, and soon will be providing reserve capacity to New York’s power grid during times of peak demand.

AES Corporation subsidiary AES Energy Storage announced the development of an 8MW battery-based storage system on Thursday. The system is located in Johnson City, New York, and is designed to improve the reliability of the state power grid.

New York Independent System Operator (NYISO), a non-profit organization that controls and monitors the operation of New York’s power grid, validated the system’s performance in late December.

“This project is meeting the reliability needs of utilities and competitive suppliers in New York with storage,” said Chris Shelton, president, AES Energy Storage. “We are excited to be working with the NYISO to deliver this important grid service from an efficient and flexible battery-based facility at utility scale."

Up to 20MW of reserve capacity will become available once the project is competed later this year. AES Energy Storage received a $17.1 million loan guarantee from the U.S. Department of Energy.

The company maintains a 12 MW installation Northern Chile as well as several small scale pilot systems in California and Pennsylvania.
