What is a pumped storage project?

2 Pumped storage projects generally involve an upper and lower reservoir; however, there are other project design concepts under consideration that would locate one or both reservoirs below ground (sub-surface) to take advantage of abandoned mines, caverns, or other storage reservoirs.

What is a pumped storage hydropower project?

Pumped storage hydropower (PSH) projects have a critical role to play in the future of sustainable energy storage and grid stability. As renewable energy sources continue to grow in popularity, PSH projects will be a crucial tool in supporting their development and integration into the grid.

What is a pumped storage project vdomdhtmlhtml?

VDOMDHTMLhtml> Pumped storage projects move water between two reservoirs located at different elevations (i.e., an upper and lower reservoir) to store energy and generate electricity.

How many pumped storage projects are there?

In the U.S., there are 40 existing pumped storage projects providing over 22,000 MWs of storage, with largest projects in Virginia, Michigan and California (Bath County, Ludington and Helms, respectively). Additionally, there currently are 51,310 MWs representing over 60 pumped storage projects in the FERC queue for licensing and permitting.

What is pumped storage hydropower (PSH)?

One of the most promising solutions is pumped storage hydropower (PSH), a form of energy storage that has been used for over a century. PSH projects store energy by pumping water from a lower reservoir to an upper reservoir, where it can be released back to the lower reservoir through a turbine to generate electricity.

What is the capacity of a pumped storage power station?

The Huizhou Pumped Storage Power Station in China has a total capacity of 2,400 MW and was commissioned in 2014. It is located in Guangdong Province and consists of four units, each with a capacity of 600 MW. The Okawachi Pumped Storage Power Station in Japan has a total capacity of 1,200 MW and was commissioned in 1999.
