Pumped-storage hydroelectricity

OverviewBasic principleTypesEconomic efficiencyLocation requirementsEnvironmental impactPotential technologiesHistoryPumped-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 ele

Technology: Pumped Hydroelectric Energy Storage

They utilise the elevation difference between an upper and a lower storage basin. Pumps driven by electric motor– generators move water from the lower to the upper basin, thereby storing potential

Technology Strategy Assessment

To store energy, water is pumped from the lower reservoir to the upper reservoir during low net electricity demand or when energy supply exceeds demand. Most PSH plants use reversible
