Pumped hydro storage is a type of energy storage technology that involves two reservoirs, one at a higher elevation and one at a lower elevation, and a pump-turbine system. During periods of low energy demand and excess energy generation, water is pumped from the lower reservoir to the upper reservoir, where it is stored.

How They Work: Pumped-Storage Power Plants

Concept. Pumped-storage power plants are structured around two bodies of water, an upper and a lower reservoir 1 (see the diagram below).. At times of very high electricity consumption on the grid, the water from the upper reservoir, carried downhill by a penstock, drives a turbine and a generator to produce electricity, which is used to meet the increased
