What is pumped storage hydropower (PSH)?

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).

What is a pumped hydroelectric storage facility?

Pumped hydroelectric storage facilities store energy in the form of water in an upper reservoir, pumped from another reservoir at a lower elevation. During periods of high electricity demand, power is generated by releasing the stored water through turbines in the same manner as a conventional hydropower station.

How do pumped hydro storage plants store energy?

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

How long does a hydroelectric pumped storage project take?

A pumped storage project would typically be designed to have 6 to 20 hours of hydraulic reservoir storage for operation at. By increasing plant capacity in terms of size and number of units, hydroelectric pumped storage generation can be concentrated and shaped to match periods of highest demand, when it has the greatest value.

What is GE pumped storage hydro (PSH)?

GE’s Pumped Storage Hydro (PSH) technology has provided them an answer to the challenges faced in its transition efforts. Switzerland aims at developing hydro storage power plants as efficient and flexible assets, to address fluctuating power demands and peaks in a financially and environmentally efficient manner.

What are pumped hydro storage technologies?

New pumped hydro storage technologies—such as variable speed capability—give plant owners even more flexibility by providing grid frequency support in both directions (in turbine and pump modes) as well as quicker response times.
