National Grid Generation has filed with the New York State Public Service Commission to lease land it owns on Long Island for a 5 MW, 40 MWh battery storage facility that would be built by a unit of NextEra Energy Resources.
The battery storage facility would be sited in East Hampton on the eastern end of Long Island and is slated to be in operation by 2018. It is expected to help the Long Island Power Authority meet peak demand on the island.
- The storage project would also serve as the receiving station for the South Fork Wind Farm, a 90 MW project proposed by Deepwater Wind.
The Long Island Power Authority has committed to procuring 280 MW of renewable capacity on Long Island, which is a constrained zone at the end of New York’s wholesale power market.
LIPA took a step toward that goal when it signed a power purchase agreement with Deepwater Wind for its 90 MW offshore wind farm proposed for the waters off Long Island’s south shore. That project also includes two battery storage installations.
The battery project in East Hampton is expected to be bigger — up to eight hours of duration — and National Grid wrote in its lease filing that the storage facility will supplement existing gas peaker plants in helping meet peak demand on the island.
In addition to the East Hampton site, National Grid and NextEra are also planning a battery storage facility in nearby Montauk at the eastern tip of Long Island.
