A New Approach to Pumped Storage Hydropower

Pumped-storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir. PSH capabilities can be characterized as open …

SummaryOverviewHistoryWorldwide usePump-back hydroelectric damsPotential technologiesSee alsoExternal links

Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the …

Hydroelectric Energy: The Power of Running Water

Hydroelectric energy is made by moving water. Hydro comes from the Greek word for water. Hydroelectric energy has been in use for thousands of years. Ancient Romans built turbines, which are wheels turned by flowing water. Roman turbines were not used for electricity, but for grinding grains to make flour and breads.
