Project Summary

ITC Midwest LLC (ITCM) has proposed to: (1) construct approximately 75 miles of new 345 kV transmission line eastward from the Lakefield substation near Lakefield, Minn., to a new Huntley substation near Winnebago, Minn. and then southward to the Minnesota-Iowa border, crossing the border near the city of Elmore, Minn., (2) expand the existing Lakefield substation and construct a new substation (the Huntley substation) which will replace the existing Winnebago substation, and (3) relocate and reconfigure several segments of existing 161 kV and 69 kV transmission line which currently terminate at the Winnebago substation such that they will terminate at the new Huntley substation upon completion of the project.  

ITCM has indicated that 345 kV transmission line poles will range from 130 to 190 feet in height, with a span between structures in the range of 700 to 1000 feet.  The transmission poles for the 161 kV portions of the project will range from 80 to 120 feet in height, with a span between structures in the range of 600 to 800 feet. 

ITCM's proposed project requires two approvals from the Minnesota Public Utilities Commission (Commission) before it may be constructed - a certificate of need (CN) and a route permit. ITCM applied to the Commission for these approvals in March 2013.

The route permit application was reviewed under the full permitting process of the Power Plant Siting Act. Upon completion of a draft and final environmental impact statement (EIS) and a public hearing process, the Commission issued a CN and route permit for project on November 25, 2014.  

ITCM anticipates that construction on the project will begin in early 2016 and be completed by mid-year 2017. 

Additional information on the CN process can be found on the eDockets website: CN-12-1053
