Putting wind to work for Carbon County

Power Company of Wyoming LLC's Chokecherry and Sierra Madre Wind Energy Project is an approximately 3,500 MW wind farm located south of Sinclair and Rawlins in Carbon County, Wyoming. The project's long-term surface disturbance will be less than 1,500 acres of a 320,000-acre ranch owned and operated by an affiliate company. The project will ensure a reliable, competitively priced supply of renewable electricity that's unmatched in the West. This output will help America reduce greenhouse-gas emissions, diversify energy sources and meet growing demand for renewable energy. At the same time, the wind project will generate hundreds of good jobs, millions of dollars in tax revenue and other economic benefits for Carbon County.

Located entirely in Carbon County, Wyoming, the wind project spans a combination of private land
owned by The Overland Trail Cattle Company LLC and federal land managed by the BLM.

"Tapping the vast renewable energy resources on our nation’s public lands will create jobs while supporting a clean energy future. Wyoming has some of the best wind energy resources in the world, and there’s no doubt that this project has the potential to be a landmark example for the nation."
- U.S. Secretary of the Interior Ken Salazar,
announcing the CCSM Wind Energy Project’s Record of Decision, Oct. 9, 2012
