FERC seeks input on license app for 240-MW pumped storage hydro project in N.Y.

The Federal Energy Regulatory Commission on Feb. 27 issued a notice of an original major license application filed on Feb. 13 by Moriah Hydro Corp. for the 240-MW Mineville Energy Storage Project, to be located in an abandoned subterranean mine complex in the town of Moriah in Essex County, New York.

The proposed project consists of: an upper reservoir in the upper portion of the mine; a lower reservoir in the lower portion of the mine; an upper reservoir shaft connecting the upper reservoir to the high-pressure penstock located below the powerhouse chamber floor; a lower reservoir shaft connecting the lower reservoir and the lower reservoir ventilation tunnel; two emergency evacuation shafts located between the powerhouse chamber and the electrical equipment chamber; a main shaft extending 2,955 feet from the surface down to the powerhouse chamber steel penstocks embedded beneath the powerhouse chamber floor; a powerhouse chamber containing 100 reversible pump-turbine units, each with a nameplate generating capacity of 2.4 MW; an underground electrical equipment chamber adjacent to the powerhouse chamber; and an inclined electrical tunnel connecting the electrical equipment chamber to a new 115-kV substation constructed adjacent to an existing single circuit 115-kV transmission line located about one horizontal mile from the underground powerhouse chamber.

The project would operate as a closed-loop system to meet energy demands and grid control requirements. It would have an average annual generation of 421 gigawatt-hours (GWh). The average pumping power used by the project would be 554 GWh.

An applicant contact is: James A. Besha P.E., President, Moriah Hydro Corp., 5 Washington Square, Albany, NY 12205, (518) 456-7712.
