What is Pumped Storage?
By Elliot Clark November 17, 2023. Pumped storage power plants are hydroelectric power stations that store and reuse energy. They have two reservoirs at different elevations to store and generate electricity. During low electricity demand, the extra energy from the grid is used to pump water from the lower reservoir to the higher one, thus
