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.
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 ...
NASA G2 flywheel. Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the ...
This system would use the high water pressure at great water depths to store energy in hollow bodies. Shortly, after their idea was published on 1 April 2011 in the newspaper Frankfurter Allgemeine Zeitung, a consortium of the Fraunhofer Institute for Energy Economics and Energy System Technology and the construction company Hochtief AG was set ...

The facility is operated by the Susquehanna Electric Company, a subsidiary of Constellation Energy. The facility's upper reservoir is the 1,000-acre (400 ha) Muddy Run Reservoir, with a full pool elevation of over 500 feet (150 m), and a usable storage capacity of 1,466 million cubic feet (33,700 acre⋅ft; 41.5 hm 3).
