Pumped-storage hydroelectricity

SummaryOverviewHistoryWorldwide usePump-back hydroelectric damsPotential technologiesSee alsoExternal links

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. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the …
