The Western Area Power Administration, an agency of the U.S. Department of Energy, has published a final environmental impact statement (EIS) on the proposed interconnection to the Western system of the Grande Prairie Wind Farm in Holt County, near the city of O’Neill, Nebraska.
The final EIS is dated December 2014. Western will issue a finding of no significant impact to wrap up its environmental review process.
Grande Prairie Wind LLC, a subsidiary of Geronimo Energy, proposes to construct and operate a 400-MW wind facility. Grande Prairie Wind proposes to erect up to 266 wind turbines. The company is considering a variety of wind turbines ranging from 1.5 MW to 3.3 MW in size.
The final EIS said a construction start is targeted in early 2015. The developer has a power purchase agreement with the Omaha Public Power District for the entire 400-MW project capacity.
Western would interconnect the project to its system at a new substation adjacent to its Fort Thompson–Grand Island 345-kV transmission line.
