Pumped hydro energy storage system: A technological review

Pumped hydroelectric energy storage stores energy in the form of potential energy of water that is pumped from a lower reservoir to a higher level reservoir. In this type of system, low cost electric power (electricity in off-peak time) is used to run the pumps to raise the water from the lower reservoir to the upper one.
