What is Pumped Storage?

Pumped storage power plants are hydroelectric power stations that store and reuse energy. They have two reservoirs at different elevations to store and generate electricity.During low electricity demand, the extra energy from the grid is used to pump water from the lower reservoir to the higher one, thus storing the energy as potential energy.

A New Approach to Pumped Storage Hydropower

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 (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir.
