Stillwater Wind is located in Stillwater County, Montana. 


Construction of the project created approximately 80 jobs within the local and regional communities and will employ approximately six full-time personnel during operations. The two construction contractors responsible for construction of the Stillwater Wind project, Dick Anderson Construction and EPC Services Company, are both headquartered in Montana.

Over the first 25 years of the facility’s operational life it is expected to produce more than $18 million in tax revenue. The local county will also receive impact fee payments over the first three years, in addition to royalty payments to participating landowners.


The facility generates renewable energy for approximately 23,000 homes, while annually offsetting the equivalent carbon emissions of 58,000 cars, and conserving water for the needs of 4,500 people.


Stillwater Wind is utilizing a total of 31 Siemens Gamesa wind turbines comprised of five 2.3 MW turbines with 108 meter rotors and 26 2.625 MW turbines with 120 meter rotors. During each year of operations, the 79.75 MW facility will generate energy equal to the needs of more than 23,000 Montana homes.

The facility interconnects to the local transmission provider’s 230-kV transmission line via a newly constructed 230-kV switching station. The facility reached commercial operations in November 2018.
