Is pumped storage energy conserved Introduction
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.A PHS system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher.

Taking into account conversion losses and evaporation losses from the exposed water surface,of 70–80% or more can be achieved.This technique is currently the most cost-effective means of storing large amounts of electrical energy, but capital costs.
Water requirements for PSH are small:about 1 gigalitre of initial fill water per gigawatt-hour of storage. This water is recycled uphill and back downhill between the two reservoirs for many decades, but evaporation losses (beyond what rainfall and any inflow from local.
The first use of pumped storage was in 1907 in , at the Engeweiher pumped storage facility near Schaffhausen, Switzerland. In the 1930s reversible hydroelectric turbines became available. This apparatus could operate both as turbine.
In closed-loop systems, pure pumped-storage plants store water in an upper reservoir with no natural inflows, while pump-back plants utilize a combination of pumped storage and conventionalwith an upper reservoir that is replenished in.
