Mineville Energy Storage (Project No. 12635) is a proposal to construct a 240-megawatt closed-loop pumped storage project in a decommissioned subterranean mine complex in Essex County, New York. The proposed project would consist of, among other facilities, upper and lower reservoirs with storage capacities of 2,448 acre-feet, low- and high-pressure penstocks, a powerhouse, an electrical chamber and tunnel, and 34.5-kilovolt transmission lines. The proposed project would provide an estimated annual generation of 421,000 megawatt-hours.
