Their special feature: They are an energy store and a hydroelectric power plant in one. If there is a surplus of power in the grid, the pumped storage power station switches to pumping mode – an electric motor drives the pump turbines, which pumps water from a lower reservoir to a higher storage basin.

Pumped Storage Report - National Hydropower Association

Pumped storage hydropower is a modified use of conventional hydropower technology to store and manage energy or electricity. Pumped storage hydropower projects use electricity to store potential energy by moving water between an upper and lower reservoir. In pumping mode, electric energy is converted to potential energy and

Apr 01, 2015  The PSHP is assumed to be able to offer spinning reserve in both operating modes; in pumping mode, it is assumed that the pump can be shut-down in order to reduce power demand. The value of energy stored in the upper reservoir at the end of the day is determined by the marginal cost of water storage at the end of the previous day.

Pumped-Storage Hydropower Department of Energy

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.
