What is a pumped storage hydropower facility?

Pumped storage hydropower facilities use water and gravity to create and store renewable energy. Learn more about this energy storage technology and how it can help support the 100% clean energy grid the country—and the world—needs.

Could a pumped hydro energy storage system bring more wind and solar online?

Plain water and a new type of turbine are the keys to a pumped hydro energy storage system aimed at bringing more wind and solar online.

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 is pumped storage hydropower important?

As the global community accelerates its transition toward renewable energy, the importance of reliable energy storage becomes increasingly evident. Among the various technologies available, pumped storage hydropower (PSH) stands out as a cornerstone solution, ensuring grid stability and sustainability.

What is a closed-loop pumped storage hydropower system?

With closed-loop PSH, reservoirs are not connected to an outside body of water. Open-loop pumped storage hydropower systems connect a reservoir to a naturally flowing water feature via a tunnel, using a turbine/pump and generator/motor to move water and create electricity.

What is pumped hydropower?

That brings us to the Energy Department’s push for more and better energy storage in the form of pumped hydropower. For those of you new to the topic, pumped hydro can take advantage of renewable energy to pump water from a lower reservoir to an upper reservoir. When the local grid needs more electricity, gravity does the rest.
