Pumped-storage hydroelectricity

OverviewBasic principleTypesEconomic efficiencyLocation requirementsEnvironmental impactPotential technologiesHistory

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. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high elec
