The Western Area Power Administration recently issued a finding of no significant impact after an environmental review of a 20-MW expansion of the Colorado Highlands Wind LLC project in Logan County, Colorado.
The Dec. 15 finding completes the administration’s environmental review of this expansion. The company wants to add up to 11 new wind turbines at this existing facility. WAPA plans to modify its interconnection agreement at the Wildhorse Creek Switching Station from the current 90 MW, to 110 MW, to account for this new capacity.
The Colorado Highlands Wind Project Expansion would be constructed on private and state land located northeast of Fleming in Logan County. The project is located east of the existing wind farm boundary, on roughly 1,200 acres of private and state land with similarcharacteristics to the existing wind project site.
The planned General Electric 1.79-MW wind turbine for this expansion project is a monopole tower design with an 80-meter hub height and a 100-meter rotor diameter.
The original project constructed in 2012 was smaller than originally intended and included only 42 wind turbines with a 67.2 MW nameplate capacity on 4,000 acres. In 2013, Colorado Highlands expanded the project through an additional 14 wind turbines to increase the nameplate capacity to 91 MW (capable of delivering only the previously approved 90 MW).
