Gordon Butte Pumped Storage Project

[1] The agency approved the request in December 2016, following a September decision of no environmental impact, granting Absaroka a 50-year license to operate Gordon Butte.

[2] Gordon Butte will be located on a 177 acres (0.72 km2) site, and will have access to water from Cottonwood Creek, a tributary of the Musselshell River.

[2] The facility will operate as a closed-loop system, without actively drawing or discharging water into the watershed.

[2][3] According to Absaroka, construction was planned to begin in 2018 or later, after design and engineering work is completed and financing is obtained.

[2] In 2019 Danish investment group Copenhagen Infrastructure Partners made a significant equity investment in the project[4] which was thought to allow construction to begin in 2020.
