Energy Storage

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.

The NYPA Board of Trustees approved $23.8 million for the project at its July 30 meeting. The total estimated project cost is $29.8 million, $6 million of which was approved by the board in October 2018. The project will include a one-hour lithium-ion battery system to absorb excess generation for later delivery.

“Energy storage is paramount as we bring more renewable energy online,“ Gil Quiniones, NYPA CEO and president, said. “To meet Governor Cuomo’s aggressive clean energy targets, we need to be able to store energy in large-scale batteries so it can be used at times of demand. This North Country battery storage project will guide us as we model additional storage facilities after it in the near future.”

Increasing energy storage capabilities also helps realize Cuomo’s Green New Deal, which aims to reduce the state’s carbon footprint to zero by 2040 and ensure that 70 percent of the State's electricity supply comes from renewables by 2030, the Authority said.

At the July 30 meeting, the NYPA Board of Trustees also approved the award of a three-year contract, selected through competitive bidding, to O’Connell Electric Company, Inc., of Victor, N.Y. in Ontario County in the amount of $22.6 million for engineering, procurement, construction and commissioning of the project.

Strategic location

NYPA said the project’s strategic location in Northern New York is significant in encouraging efficient, reliable renewable energy growth.

More than 80 percent of the region’s electricity supply comes from renewable resources, including NYPA’s St. Lawrence hydropower project and more than 650 MW of wind generation. Having the capability to store renewable energy for later delivery will help eliminate current transmission constraints that can prevent the energy from being delivered downstate.

The Authority’s purchase of the property for the battery facility is currently in negotiations and expected to be finalized prior to construction start this fall. The energy storage system will supply the New York wholesale energy and ancillary service markets and will contribute to the adequacy, economy and reliability of the supply of electric power in New York, the Authority said.  

Construction is expected to start in October, with operation anticipated by June 2020.
