Pumped hydro energy storage projects planned across georgia

How does a pumped storage hydropower project work?

Pumped storage hydropower projects use electricity to store potential energy by moving water between an upper and lower reservoir. Using electricity from the grid to pump water from a lower elevation, PSH creates potential energy in the form of water stored at an upper elevation, which is why it is often referred to as a “water battery”.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) is a proven energy storage technology. Its earliest U.S. operations date back to the 1929 commissioning of the Rocky River PSH project in Connecticut .

What is a pumped storage hydro?

A-PSH: Advanced pumped storage hydro (Variable Speed) This type of hydro pump storage is based on a C-PSH utilizing a Francis type reversible pump-turbine, with variable speed capabilities. This capability is made possible with the use of power electronics that varies the AC frequency on the pump end.

Why do we need hydropower and pumped storage?

The combination of increasing variable renewable resources and the retirement of fossil fueled dispatchable capacity makes hydropower and pumped storage the unique proven technology that can provide clean energy, flexibility and storage.

When should Pondage Hydro and pumped-hydro storage be scheduled?

Other clean energy resources like pondage hydro and pumped-hydro storage can be scheduled to provide their clean energy when it is the most valuable, both for reliability and for emission reduction purposes.

What is a pumped storage hydropower guidance note?

The guidance note delivers recommendations to reduce risks and enhance certainty in project development and delivery. It also equips key decision-makers with the tools to effectively guide the development of pumped storage hydropower projects and unlock crucial finance mechanisms.
