The Mt. Hope Waterpower Project is a 2000 megawatt, underground pumped-storage hydroelectric power project located on the site of an inactive iron mine in the township of Rockaway, New Jersey, about 35 miles west of New York City. From the upper reservoir, water will flow to the powerhouse down a vertical intake shaft with a depth of 2800 ft. Water will operate five single-stage reversible Francis-type pump-turbines with adjustable inlet vanes and vertically arranged shafts running at 600 rpm, with direct shaft drive to the motor generators mounted above them. The motor generators will be of synchronous design. The lower reservoir will be located at 2500 ft below ground and will be excavated entirely from the living rock. Details of the project are described. When completed, the project will be one of the world's biggest pumped-storage plants.
