Carbon County, Wyoming, is the proposed site for the largest-to-date onshore wind farm in the United States. Power Company of Wyoming proposes to build up to 1,000 turbines in Carbon County, a proposal which has been approved by the Industrial Siting Council 7-0. Known as the Chokecherry and Sierra Madre project, the proposed $5 billion plan could produce up to 3,000 megawatts of electricity, or 10 million megawatt hours annually. The ruling by the Industrial Siting Council moves the plan one step closer to becoming a reality, and it seems to be proceeding without much opposition. During the two day hearing, council members noted that no one spoke in opposition to the project. According to Richard O'Gara, a Cheyenne Democrat, "It was probably the most professional presentation I've ever seen. There was virtually no opposition." This sentiment seems to be the same across party lines. Siting council chairman Shawn Warner, a Powell Republican admits to entering the presentation a little apprehensive about such a large project. It seems his fears were assuaged though, as he says "They did a first-class job in submitting what was required, they literally left no stone unturned."

The project's final aim is to sell electricity to Arizona, California and Nevada, three states that have renewable-energy standards requiring them to utilize renewables to bolster their supply of generated power. The plan predicts an 8-year construction once the approval process is finalized.
