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 is by far the largest-capacity form of grid energy storage available, and, as of 2020, accounts for around 95% of all active storage installations worldwide, with a total installed throughput capacity of over 181 GW and a total installed storage capacity of over 1.6 TWh.
Pumped hydro storage has the potential to ensure the grid balancing and energy time-shifting of intermittent renewable energy sources, by supplying power when demands are high and storing it when generation is high.
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).
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.
Feasibility studies using GIS-MCDM were the most reported method in studies. Storage technology is recognized as a critical enabler of a reliable future renewable energy network. There is growing acknowledgement of the potential viability of pumped hydro energy storage solutions, despite multiple barriers for large-scale installations.
