Pumped storage

Pumped storage is the process of storing energy by using two vertically separated water reservoirs. Water is pumped from the lower reservoir up into a holding reservoir. Pumped storage facilities store excess energy as gravitational potential energy of water. Since these reservoirs hold such large volumes of water, pumped water storage is considered to be a large scale

Pumped-storage hydroelectricity

OverviewHistoryBasic principleTypesEconomic efficiencyLocation requirementsEnvironmental impactPotential technologies

The first use of pumped storage was in 1907 in Switzerland, at the Engeweiher pumped storage facility near Schaffhausen, Switzerland. In the 1930s reversible hydroelectric turbines became available. This apparatus could operate both as turbine generators and in reverse as electric motor-driven pumps. The latest in large-scale engineering technology is variable speed machines for greater efficiency. These machines operate in synchronization with the network frequency w

Pumped Storage

Pumped storage facilities are built to push water from a lower reservoir uphill to an elevated reservoir during times of surplus electricity. 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".
