6 FAQs about [Pumped hydropower storage is out of service]
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).
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 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.
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.
Is pumped storage hydropower the best resource for long-duration energy storage?
“Pumped storage hydropower has proven to be America’s most effective resource for long-duration energy storage,” said Cameron Schilling, NHA’s Vice President of Market Strategies and Regulatory Affairs. “The acceleration of wind and solar deployments underscores the increasing need to integrate large amounts of variable resources.
Is pumped storage hydropower the world's water battery?
