Beaver Creek Transmission Line Project (Iowa)

Dairyland Power Cooperative (Dairyland) is proposing the build of approximately 9.8 miles of new 161,000 nominal voltage (161 kV) electrical transmission line, of which approximately 6.3 miles is to be in Howard County, Iowa, and approximately 3.5 miles is to be in Fillmore County, Minn. The proposed line is a network upgrade to provide transmission capacity for wind energy to be generated at the North Hills Wind Project while maintaining safety and reliability of the existing transmission network.


The preferred project route commences along 171st Ave in Fillmore County, Minn., approximately 3.5 miles north of the Iowa and Minnesota border, where an existing Dairyland 161 kV transmission line crosses the public road. The preferred route then continues to the south and west, following predominately along public roads, to a terminus along 40th Street in Howard County, Iowa, approximately 0.5 mile west of the intersection of 40th Street and James Ave., where a second Dairyland 161kV transmission line crosses the public roadway. A new switchyard is to be installed at the terminus point and will serve as the point of generation interconnection for the wind energy. Following the proposed construction, approximately 4 miles of existing transmission line in Fillmore County, Minn., will be retired.
