Pumped hydro storage uses two water reservoirs which are separated vertically. In times of excess electricity, often off peak hours, water is pumped from the lower reservoir to the upper reservoir. When required, the water flow is reversed and guided through turbines to generate electricity. | Tue, 11/08/2016.
