6 Frequently Asked Questions about “Has the Washington pumped hydro storage project started ”

Will Washington's first pumped storage project be built near John Day Dam?

Rye Development of Boston is hoping to build Washington's first pumped storage project for $2 billion in southern Klickitat County near the John Day Dam and having it in operation between 2028 and 2030. The project would include two lined 600-acre water reservoirs that are 60 feet deep and separated by 2,100 feet in elevation.

How many pumped storage hydropower sites are there?

Today, the U.S. has 42 pumped storage hydropower sites producing roughly 29,000 megawatts of electricity, slightly more than 2% of the nation's power, according to a 2018 report by the National Hydropower Association. Fifty-three other projects totaling almost 26,000 megawatts are in various stages of obtaining federal, state and local permits.

What is pumped storage hydropower?

Pumped storage hydropower is a method of storing energy by pumping water to a higher elevation during periods of lower demand and then releasing it to generate electricity when demand is high. Steimle explains that this method is often used to increase the efficiency of nuclear power plants, allowing them to run at a constant rate which is the most efficient way for them to operate.

Which companies are developing pumped storage in the Pacific Northwest?

Rye Development is the first company to pursue the pumped storage concept in the Pacific Northwest. Besides the Klickitat County project, Rye Development is developing a similar 400 megawatt pumped storage project at Swan Lake in southern Oregon. That $800 million project is scheduled to go online in 2026.

What pumped storage projects are coming to Oregon?

Besides the Klickitat County project, Rye Development is developing a similar 400 megawatt pumped storage project at Swan Lake in southern Oregon. That $800 million project is scheduled to go online in 2026. The Klickitat and Swan Lake projects are Rye Development's first ventures into pumped storage.

Where is the Goldendale pumped storage hydropower station located?

The Goldendale pumped storage hydropower station will be primarily located in Klickitat County, Washington, with a 681.6-acre site on private lands northeast of Portland and southwest of Kennewick, on the Columbia River, next to John Day Dam. The transmission line extends into Sherman County, Oregon.
