concept of pumped storage power station

Pumped-Storage Hyro Plants

A pumped-storage plant works much like a conventional hydroelectric station, except the same water can be used over and over again. Water power uses no fuel in the generation of electricity, making for very low operating costs. ... When power from the plant is needed, water stored in an upper reservoir is released into an underground tunnel ...
