Heron Lake-Lakefield 161 kV Transmission Line rebuild
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…

Battle Creek-Island Road Transmission Line Rebuild
Portions of the electric transmission grid in Michigan, including the Battle Creek-Island Road 138,000 volt (138kV) transmission line, were built more than 50 years ago and have experienced minimal investment since that time. As a result, this line has become increasingly unreliable and costly to maintain as growing demand for electricity and outdated infrastructure technology…
