ITC Midwest rebuilt an existing 161 kV transmission line in southwest Minnesota between its Heron Lake and Lakefield substations. The project consisted of replacing existing wood “H” frame structures with single steel pole structures. To minimize impact on local landowners, ITC Midwest used the existing line route as much as possible. Approximately 11 miles of the project is single circuit 161 kV line. Approximately six miles of line is double-circuited with an existing 69 kV line in the area. The project was completed in 2013.
