Putting Wind To Work For Carbon County

Power Company of Wyoming LLC's Chokecherry and Sierra Madre Wind Energy Project is a 3,000 MW capacity wind farm located south of Sinclair and Rawlins in Carbon County, Wyoming. The project will ensure a reliable, competitively priced supply of renewable electricity that's unmatched in the West. 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.

  • About 600 wind turbines
  • Over 3,000 MW nameplate capacity
  • Best winds in the country – Class 6-7
  • $5 billion estimated cost
  • About 50% sited on private land and 50% on federal land in Carbon County.

The Chokecherry and Sierra Madre Wind Energy Project (CCSM Project) will have the wind turbines and electric infrastructure necessary to reliably and cost-effectively generate over 3,000 megawatts of clean, sustainable electricity. It is situated on land that has some of the best winds in the state and in the country. The project area has Class 6 and 7 winds, which are the highest wind classes. Final turbine models have yet to be selected, but each turbine is anticipated to provide 4MW to 6MW of nameplate capacity. The wind project is estimated to produce enough clean electricity to power approximately 1 million households, resulting in a reduction in CO2 emissions of 7 million to 11 million tons per year. The wind turbines will be constructed in two phases of 1,500 MW each. Phase I consists of 225 turbines, and Phase II consists of about 375 turbines.
