Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with ...
The upper reservoir can hold about 1.5 billion US gallons (4,600 acre-feet; 5.7 million cubic metres) of water behind a wall nearly 100 feet (30 m) tall. [12] It sits 760 feet (230 m) above the 450 MW hydroelectric plant, which gives it a greater head than that of Hoover Dam.
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
The Ludington Pumped Storage Plant is a hydroelectric plant and reservoir in Ludington, Michigan. It was built between 1969 and 1973 at a cost of $315 million and is owned jointly by Consumers Energy and DTE Energy and operated by Consumers Energy. At the time of its construction, it was the largest pumped storage hydroelectric facility in the ...
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.
The energy storage capacity of the station is approximately 9.1 GWh. [2] At peak output water flows through the generators at 390 cubic metres (86,000 imperial gallons) per second (about the volume of a 25 m (27 yd) swimming pool every second). [15]

The kinetic energy of flowing water is the main source of energy. [13] Both designs have limitations. For example, dam construction can result in discomfort to nearby residents. The dam and reservoirs occupy a relatively large amount of space that may be opposed by nearby communities. [19]
