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 …
