The Blenheim–Gilboa Pumped Storage Power Station is a pumped-storage hydroelectricity plant in the Catskill Mountains of New York State. The plant is part of the New York Power Authority, and can generate over 1,100 megawatts (1,500,000 hp) of electricity. It is used daily to cover peak demand. There are two reservoirs that are involved in the project, both with a capacity of 5 billion US gallons (19,000,000 m3); one at the foot of Brown Mountain in the Schoharie Valley, and another one at the top of the mountain. The power station has an accumulated capacity of about 12,000 megawatt-hours (43,000 GJ) after storing up to 17,000 megawatt-hours (61,000 GJ).
