OverviewBasic principleTypesEconomic efficiencyLocation requirementsEnvironmental impactPotential technologiesHistory

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. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through

6 FAQs about [Pumped storage dictionary]

What is pumped storage?

Pumped storage is a method of using power at a period of low demand to pump water back up to a high storage reservoir. This water can then be released to generate electricity at a period of peak demand.

What is pumped water storage?

Water is pumped from the lower reservoir up into a holding reservoir. Pumped storage facilities store excess energy as gravitational potential energy of water. Since these reservoirs hold such large volumes of water, pumped water storage is considered to be a large scale energy storage system.

What is pumped-storage hydroelectricity?

Why is pumped storage economical?

This is a result of the energy lost pumping the water up into the reservoir. However, pumped storage is economical because of a net increase in revenue. This is because the electricity used to pump the water is less expensive than the electricity sold at the time of peak energy demand.

How does a pumped storage system work?

Pumped storage is a system for generating hydroelectric power for peak periods by pumping water from a lower to a higher reservoir during low-demand periods. This stored water is then released during peak periods to generate electricity.

What is a pumped storage plant?

Pumped storage plants, like other hydroelectric plants, can respond to load changes within seconds. The most important use for pumped storage has traditionally been to balance baseload powerplants, but they may also be used to abate the fluctuating output of intermittent energy sources.
