New York 110MW Holtsville Energy Storage project approved

October 16, 2023

Holtsville Energy Storage, a 110 MW, four-hour, battery energy storage facility in Brookhaven, New York, has received construction and operational approval by the New York State Public Service Commission.

Holtsville Energy Storage, which will be developed by a company of the same name, will be located on three land parcels – covering six acres – on the southwest corner of Expressway Drive South and Morris Avenue.

The facility will connect to Long Island Power Authority’s (LIPA’s) existing 8 kW West Bus Substation. “While a utility or large energy user may purchase the output of the facility, a significant portion of the energy itself will flow to the nearest energy users,” a statement said.

Holtsville Energy Storage has said the project has the potential to create approximately 150 local jobs during construction, “plus some long-term jobs” once operational.
