Colorado Highlands Wind Project, Logan County, Colorado

DOE’s Western Area Power Administration issued a draft supplemental EA that assesses the potential environmental impacts of the proposed expansion of Colorado Highlands Wind Project, which interconnects to Western’s transmission system. Western assessed the initial proposal (60 wind turbine generators with a total output nameplate capacity of 90 megawatts (MW)) in an EA issued in 2009. The proposed expansion is for 11 wind turbine generators that would add approximately 20 MW.
