New York has opened its first state-owned utility-scale energy storage facility.

Located in Chateaugay, Franklin County, the 20-megawatt facility will be operated by the New York Power Authority and connects to the state’s electrical grid. Constructed by Victor-based O’Connell Electric Company Inc, the site provides 20 MW of power, through a lithium-ion battery system.

“Deploying energy storage technologies make our power supply more reliable and resilient, further enabling New York to build a robust clean energy grid,” Governor Hochul said. “The completion of the Northern New York Energy Storage project marks an important step to reaching New York’s energy storage and climate goals.”

The facility consists of five 53-foot walk-in enclosures. Each enclosure contains over 19,500 batteries, allowing for enough energy to power roughly 3,000 homes.

The project hopes to accelerate New York’s goal of installing 6,000 MW of energy storage by 2030.
