OverviewBasic principleTypesEconomic efficiencyLocation requirementsEnvironmental impactPotential technologiesHistory

A pumped-storage hydroelectricity generally consists of two water reservoirs at different heights, connected with each other. At times of low electrical demand, excess generation capacity is used to pump water into the upper reservoir. When there is higher demand, water is released back into the lower reservoir through a turbine, generating electricity. Pumped storage plants usually use re

Pumped Storage Power Station (Francis Turbine)

Pumped storage power plants purchase power at night to pump water up to the upper reservoir, they then generate power and sell it back to the grid during the day, when the demand -and

Pumped Storage Power Station (Francis Turbine)

How Pumped Storage Plants WorkHow Pumped Storage Plants Generate PowerHow Pumped Storage Plants Store Potential EnergyWater is pumped from the lower reservoir to the upper reservoir by the Francis turbine runner. The flow path is the same as when generating electricity, except the flow direction is reversed because the Francis runner is used as a pump instead of a turbine.See more on savree International Hydropower Association

Pumped storage hydropower (PSH) is a form of clean energy storage that is ideal for electricity grid reliability and stability. PSH complements wind

Pumped Storage

In pumping mode, electric energy is converted to potential energy and stored in the form of water at an upper elevation, which is why it is sometimes called a "water battery".

Pumped storage hydropower facilities rely on two reservoirs at different elevations to store and generate energy. When other power

Technology: Pumped Hydroelectric Energy Storage

Pumps driven by electric motor– generators move water from the lower to the upper basin, thereby storing potential energy. For electricity generation, the stored water flows back down
