The existing 161,000 megawatts (MW) of pumped storage capacity supports power grid stability, reducing overall system costs and sector emissions. A bottom up analysis of energy stored in the world''s pumped storage reservoirs using IHA''s stations database estimates total storage to be up to 9,000 gigawatt hours (GWh).
Pumped hydro storage is complementary to hydroelectric generation, and its concept of operation is quite simple, as shown in Fig. 6.1. During periods of high demand, water from the upper reservoir is released with large momentum through water turbines, where the substantial water head stored behind dam walls converts the potential
