FAQs about How does a pumped storage power plant work

How does a pumped storage plant generate electricity?

Pumped storage plants convert potential energy to electrical energy, or, electrical energy to potential energy. They achieve this by allowing water to flow from a high elevation to a lower elevation, or, by pumping water from a low elevation to a higher elevation. When water flows to a lower elevation, the power plant generates electricity.

Pumped hydro storage plants store energy using a system of two interconnected reservoirs with one at a higher elevation than the other.

How is water pumped in a storage plant?

Water is pumped from the lower reservoir to the upper reservoir by the Francis turbine runner. The flow path is the same as when generating electricity, except the flow direction is reversed because the Francis runner is used as a pump instead of a turbine. Pumped storage plants rely upon the varying price of electricity to make a profit.

How does a power plant work?

When there's a sudden demand for power, the “head gates” are opened, and water rushes down the tunnels to drive the turbines, which drive the powerful generators. This is called generation cycle. The water then collects in the lower reservoir, ready to be pumped back up later.
