What is pumped hydro storage?
Glossary Pumped Hydro Storage (PHS): A type of hydroelectric power generation that stores and manages energy by moving water between two reservoirs at different elevations.

What is pumped-storage hydroelectricity?
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 PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
How do pumped hydroelectric energy storage systems work?
In pumped hydroelectric energy storage systems, water is pumped to a higher elevation and then released and gravity-fed through a turbine that generates electricity. Conventional hydroelectric storage systems rely on natural elevation differentials between water bodies on the Earth's surface to store energy.
What is pumped storage hydro (PSH)?
During periods of low energy demand on the electricity network, surplus electricity is used to pump water to the higher reservoir. When electricity demand increases, the stored water is released, generating electricity. Pumped storage hydro (PSH) must have a central role within the future net zero grid.
