efficiency of pumped storage power station
Spotlight on pumped storage
Many existing pumped storage facilities are decades old, and are undergoing rehabilitation to extend plant life and increase capacity and/or efficiency. New construction of pumped storage hydropower is coming off a 15-year lag for major facilities, and more than 20 projects are currently in the FERC permitting process.

How Pumped Storage Hydropower Works | Department of Energy
To generate electricity when power from the plant is needed, water flows from the upper reservoir, because of gravity, through turbine (s) that rotate generator (s) to produce electricity. The water then flows into the lower reservoir where it remains until electricity demand lowers. When this occurs, the turbines spin backward to pump the
