The second environmental assessment for what may become the nation’s largest wind farm has been released by the U.S. Bureau of Land Management, along with a so-called draft finding of no new significant impact. The design consists of 1,000 wind turbines in Carbon County, Wyo., to be constructed in two phases at an estimated $5-billion cost. If both stages are completed, it would bring the capacity to 3000 MW. A 725-mile, $4-billion transmission line is planned by Transwest Express LLC to deliver the power to a hub near Las Vegas for transmission to markets in the western U.S.
