"Pumped hydro moves water to an upper reservoir when there is surplus renewable energy generation and demand for electricity is low. It is released back down to a hydro power station to generate electricity when demand is high. "It works like a battery because the stored energy in the water is released when it is used in the hydroelectric dam.
