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.

Bear Swamp Generating Station or Jack Cockwell Station is a pumped-storage hydroelectric underground power station that straddles the Deerfield River in Rowe and Florida, Massachusetts. The reservoir covers 88 acres (36 ha), storing about 1.7 billion gallons at an elevation of 1,600 feet (490 m) above sea level, 770 feet (230 m) higher than the ...
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 plant serves as an important element for peak power generation and grid balancing in the TVA system. Construction was started in 1970 and was completed in 1978. [7] The plant was idled in March 2012 due to cracks in the generators' rotors. The plant came entirely back on line in April 2014. [8] Diagram of the facility The underground powerhouse

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 underground power station is near Wishon Reservoir and houses three 404 MW Francis pump turbine-generators. [3] [4] The Helms Pumped Storage project was designed to be used with the Diablo Canyon Nuclear Power Plant, also owned by PG&E, in the 1970s, when Diablo Canyon was being designed and permitted. It is connected to that power plant by ...
