Energy Storage

Largest battery storage facility in N.Y. history is approved

The New York State Public Service Commission on Oct. 17 approved construction of the largest battery storage facility in New York State history.

The Ravenswood energy storage facility will be built on a portion of the Ravenswood Generating Station property in Long Island City, Queens, New York.

The project will include enough lithium-ion batteries to supply up to a maximum of eight hours of storage capacity at its rated output and will be able to charge and discharge up to 316 MW of power.

According to the developer, Ravenswood Development, LLC, the project will store electricity drawn from the grid and generated by other facilities. Stored energy would then be released to the grid in accordance with New York Independent System Operator’s and Consolidated Edison Company of New York, Inc.’s dispatch orders.

The energy storage facility, expected to be partially operational by March 2021, will be able to provide peak capacity, energy and ancillary services, offset more carbon-intensive on-peak generation with power stored during the off-peak period, and enhance grid reliability in New York City, the PSC said.

The project would be developed in an area of the Ravenswood Generating Station that currently is occupied in part by peaker units, most of which are currently not in service.

NYPA moves forward with large-scale storage project

The New York Power Authority (NYPA) on July 30 said it is moving ahead with its first large-scale energy storage project, establishing a 20-megawatt demonstration facility adjacent to an existing substation in Northern New York.

The new system in Franklin County, N.Y., will support New York Gov. Andrew Cuomo’s renewable energy and energy storage mandates recently signed into law in the Climate Leadership and Community Protection Act. The project supports the state’s 3,000 MW by 2030 storage goal, NYPA said.
