This method stores energy in the form of water, pumped from a lower elevation reservoir to a higher elevation. In pumped hydroelectric energy storage systems, water is pumped to a higher elevation and then released and gravity-fed through a turbine that generates electricity.
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 energy storage system.
Water can be run through turbines from the upper reservoir to the lower one and hence produces electricity. But then water can be pumped back up to the storage area at the higher elevation, effectively recharging the system. In this case, it is also possible to use two-way turbines.
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.
The amount of energy stored depends on the mass of water pumped and the height difference between the reservoirs. Pumped storage is a dispatchable source of energy since it can be deployed whenever demand is needed. It is often used to meet demand when intermittent, non-dispatchable sources, such as wind and solar power, cannot do so.
Retrieving the energy can then be achieved by releasing the water back from the higher into the lower reservoir through a turbine, in which the flow of water generates electricity. For pumped storage electricity to be feasible, there must be an elevated reservoir with a very large capacity.
