Developer Moriah Hydro Corp. has filed a draft hydropower license application, seeking Federal Energy Regulatory Commission approval of the 260-MW Mineville pumped-storage project, to be located completely underground in an abandoned mine complex in New York.
Albany Engineering Corp. filed the draft application Oct. 4 on behalf of Moriah Hydro. Albany Engineering and Stuyvesant, N.Y., recently received a FERC relicense for the rehabilitated 4.32-MW Stuyvesant Falls project (No. 2696).
Moriah Hydro proposes that the Mineville project (No. 127635) be constructed at the town of Moriah, N.Y., within the interconnected Old Bed, New Bed, Bonanza open pit, and Harmony mines, which had been developed by Republic Steel Corp. and its predecessors. The mine extends from a surface elevation of 1,263 feet above mean sea level downward 4,000 feet.
The project is to use no stream or other body of water nor to utilize any dam or spillway. The upper reservoir is to be located in the mine between 495 and 1,095 feet MSL, while the lower reservoir would be between -1,075 and -1,555 feet MSL. Each reservoir would hold about 2,448 acre-feet.
Mineville’s underground powerhouse is to contain 20 pump-turbine generator power trains of five reversible pump-turbines in each, totaling 260 MW and capable of generating 737.6 million kWh annually. It would connect by underground transmission lines to an existing transmission line a mile away from the project. The pumped-storage project would operate in generation or storage mode depending on system demands
The project is not located on U.S. lands, National Wild and Scenic Rivers areas, or Wilderness Act areas. There are no Indian tribes in the project area.
