What is pumped storage hydropower (PSH)?
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 as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
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 storage plants work?
Pumped storage plants pump water to higher elevation reservoirs at times when there is a surplus of electricity, to then release this water into lower elevation reservoirs to generate electricity when needed. With pumped storage technology, hydropower operators can quickly respond to fluctuations in electricity supply and demand.
