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).

Why do hydropower plants need a power converter?

The fact that the rotational speed of the generator can be adjusted brings a new dimension to operating a hydropower plant with optimum efficiency. In addition, operating the AS-PSH with a power converter makes it possible to operate the system in a fast and flexible manner, thus contributing to power system stability.

What is pumped hydropower storage (PHS)?

Pumped hydropower storage (PHS) is currently the only electricity storage technology able to offer large-scale storage as that needed for accommodating renewable electricity under the 2020 EU energy targets.

What is adjustable-speed pumped storage hydropower (as-PSH)?

Adjustable-speed pumped storage hydropower (AS-PSH) technology has the potential to become a large, consistent contributor to grid stability, enabling increasingly higher penetrations of wind and solar energy on the future U.S. electric power system.
