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.
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).
Pumped hydropower storage (PHS), also known as pumped-storage hydropower (PSH) and pumped hydropower energy storage (PHES), is a source-driven plant to store electricity, mainly with the aim of load balancing.
Pumped storage power plants are used to balance the frequency, voltage and power demands within the electrical grid; they are often utilized to add additional megawatt capacity to the grid during periods of high power demand. For this reason, pumped storage plants are referred to as ‘ peaking ’ plants. Electrical Grid Power Demand Graph
Pumped storage plants convert potential energy to electrical energy, or, electrical energy to potential energy. They achieve this by allowing water to flow from a high elevation to a lower elevation, or, by pumping water from a low elevation to a higher elevation. When water flows to a lower elevation, the power plant generates electricity.
The upper reservoir, Llyn Stwlan, and dam of the Ffestiniog Pumped Storage Scheme in North Wales. The lower power station has four water turbines which generate 360 MW of electricity within 60 seconds of the need arising. Along with energy management, pumped storage systems help stabilize electrical network frequency and provide reserve generation.
