Pumped hydro storage (PHS) is a form of energy storage that makes use of hydropower. It is the most widely used form of large-scale energy storage in the world. The concept involves moving water between two reservoirs at different elevations to store and generate electricity.
The pumped hydro energy storage system (PHS) is based on pumping water from one reservoir to another at a higher elevation, often during off-peak and other low electricity demand periods. When electricity is needed, water is released from the upper reservoir through a hydroelectric turbine and collected in the lower reservoir .
The efficiency of pumped hydro storage systems is typically between 70% and 80%, meaning that a significant portion of the energy used to pump the water can be recovered during the generation process.
