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

Pumped Hydro Storage | SpringerLink

The pumped hydro storage part, shown in Fig. 6.2, initiates when the demand falls short, and the part of the generated electricity is used to pump water from the lower reservoir back into the upper reservoir.Since this operation is allowed to take place for a time duration from six to eight hours (before the demand surges up again the next day),

Pumped Storage Projects | Federal Energy Regulatory Commission

Pumped storage projects move water between two reservoirs located at different elevations (i.e., an upper and lower reservoir) to store energy and generate electricity. Generally, when electricity demand is low (e.g., at night), excess electric generation capacity is used to pump water from the lower reservoir to the upper

Navigating the Pumped-Storage Development Life Cycle

The need for energy storage is growing in response to the continued development of renewable energy sources (e.g., wind and solar power). Although battery storage can provide energy on a small scale, the only large-scale proven technology for energy storage is pumped-storage hydropower.
