Voith Hydro supplying pumped storage equipment for Idaho combined energy project

Cat Creek Energy and Water has chosen Voith Hydro to design, manufacture and install 720 MW of ternary pumped storage equipment for the Cat Creek Energy and Water (CCEW) Project planned near Mountain Home, Idaho.

The overall project, on the South Fork of the Boise River, includes wind and solar generation parks and the pumped-storage plant. These plants, along with the associated electrical transmission facilities and structures, and a very large upper reservoir, will provide more than $1 billion in U.S. manufacturing and construction jobs over the next six years and will offset more than 2.7 million metric tons of CO2 emissions annually, according to Voith Hydro.

The CCEW project addresses many key national and regional issues, including the transition to providing firm, resilient and reliable renewable energy; mitigating long-term effects of climate change; and securing a significant portion of the future water storage needs in the Boise River Basin.

“The CCEW project was uniquely conceived to address the needs for renewable energy and water storage with the best technologies available and with the highest degree of flexibility to adjust to future needs. By selecting Voith Hydro ternary units, we lock in the most capable technology for the pumped storage facility and confirm our intent to build this critical infrastructure project with American steel manufactured in America,” said John Faulkner, owner of Cat Creek Energy.

When completed, the CCEW Project will have a capacity of 1,100 MW of clean, renewable energy. The upper reservoir will store enough water to support more than 40% of the projected water supply needs of the Boise River Basin. This stored water volume will provide five complete days of full generation capacity from the pumped storage facility, creating one of the most significant large volume, long duration energy storage facilities in the western U.S. The energy to power the pumps will come from on-site wind turbine and photovoltaic solar panel arrays, as well as other variable renewable energy resources around the region.

“Voith Hydro is all in when it comes to supporting the renewable energy transition and climate change goals in the U.S. and around the world,” said Stanley J. Kocon, president and chief executive officer of Voith Hydro North America. “This project will be the most advanced large-scale, fully integrated energy and water storage project ever constructed in the U.S. and we’re excited to be partnered with Cat Creek Energy right from the start.”
