Pumped-Storage Hydroelectricity

Hydro Power. T. Hino, A. Lejeune, in Comprehensive Renewable Energy, 2012 6.15.3.1 Characteristics. Pumped storage hydroelectricity works on a very simple principle. Two reservoirs at different altitudes are required. When the water is released from the upper reservoir, energy is generated by the down flow, which is directed through high-pressure shafts, linked to turbines.
