At full build‐out, the Grande Prairie Wind Farm (Project) would include up to 266 wind turbines with a combined generating capacity of up to 400 megawatts (MW) of renewable energy. Other proposed Project facilities would include access roads, temporary crane paths, underground power collection lines, aboveground generation-tie (gen-tie) line, two collector substations, one interconnection switchyard, six or more permanent meteorological towers, temporary meteorological towers, and an operations and maintenance building. Grande Prairie Wind has applied to Western to interconnect the proposed Project to Western’s 345-kilovolt (kV) Fort Thompson to Grand Island transmission line at a new switchyard. The Draft EIS includes a description of Western’s proposed Federal action and an analysis of environmental effects that would occur as a result of proposed Project alternatives, including a No Action alternative. Western invites interested parties to comment on this Draft EIS during the 45-day comment period that will begin when the Environmental Protection Agency publishes a Notice of Availability of this Draft EIS in the Federal Register. 1 Midwest Wind Energy previously owned Grande Prairie Wind and made the original interconnection requests on August 22, 2007 (0117) and September 26, 2007 (0718) now being considered as a single request.
