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.
In the event of a power outage, a pumped storage plant can reactivate the grid by harnessing the energy produced by sending "emergency" water – which is kept in the upper reservoir for this very purpose – through the turbines. Pumped storage hydropower plants fall into two categories:
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).
Pumping in these plants is referred to as "voluntary pumped storage." Internationally, the largest pumped storage hydropower plant is Fengning in China, with a capacity of 3.6 GW and a storage capacity of 40 GWh, surpassing the Bath County plant in Virginia (USA), with 3 GW of power and 24 GWh of capacity.
The Fengning Pumped Storage Power Station is the one of largest of its kind in the world, with twelve 300 MW reversible turbines, 40-60 GWh of energy storage and 11 hours of energy storage, their reservoirs are roughly comparable in size to about 20,000 to 40,000 Olympic swimming pools.
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.
