Pumped storage power plants purchase power at night to pump water up to the upper reservoir, they then generate power and sell it back to the grid during the day, when the demand -and price- is higher. Example 1 Power is purchased from the grid at 1ct/kWh to pump water from the lower to upper reservoir.
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 hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
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 .
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 as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
The two reservoirs, an upper and a lower, together form a pumped-storage power system. Pumped-storage power plants are structured around two bodies of water, an upper and a lower reservoir 1 (see the diagram below).

How They Work: Pumped-Storage Power Plants
Pumped-storage power plants are reversible hydroelectric facilities where water is pumped uphill into a reservoir. The force of the water flowing back down the hill is then harnessed to produce electricity in the same way as conventional hydroelectric plants.

What are pumped storage power plants and how do they work?
Pumped storage power plants involves using the force of gravity to generate electricity using water that has previously been pumped from a lower source to an upper reservoir. This means that water is pumped to a higher source during periods of high renewable energy production and lower demand, when electricity prices are low. However, during ...

Pumped Storage Hydropower Plants
The basic operating principle is similar for all of them: water flows through a turbine to generate electricity. However, unlike run-of-river or reservoir power plants, pumped storage plants enable us to store and schedule hydroelectric power generation, while also playing a crucial role in stabilizing the power grid.
