Is pumped hydropower storage a traditional energy source

Plants that do not use pumped storage are referred to as conventional hydroelectric plants; conventional hydroelectric plants that have significant storage capacity may be able to play a similar role in the electrical grid as pumped storage if appropriately equipped.OverviewPumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of used by for . A PSH system stores energy in the for. . A pumped-storage hydroelectricity generally consists of two water reservoirs at different heights, connected with each other. At times of low electrical demand, excess generation capacity is used to pump water into the up. [pdf]
