Application Summary
Overview
American Transmission Company (ATC or applicant) is seeking approval to construct a new 115 kV transmission line from the existing Pine Substation (to be expanded) to the existing Hilltop Substation. The Proposed Route would route through the City of Merrill and the Town of Pine River in Lincoln County and the towns of Texas and Stettin and the Village of Maine in Marathon County. The Alternative Route would route through the City of Merrill and the towns of Pine River and Scott in Lincoln County and the Village of Maine and the Town of Stettin in Marathon County. Pine Substation would be expanded.
The Proposed and Alternative Routes would be constructed as a single-circuit, 115 kV transmission line on self-supporting steel monopole structures. The Proposed Route would be approximately 17.7 miles in length. The Alternative Route would be approximately 22.1 miles in length. There is approximately 2.2 miles of Common Segments that would be used by either Proposed or Alternative routes if approved. There are several existing distribution lines that are located in roadside along the Proposed and Alternative routes that may require removal and relocation.
A total of 35 percent of the Proposed Route exists within shared right-of-way (ROW), 41 percent of the Alternative Route exists within shared ROW, and 52 percent of the Common Route exists within shared ROW.

Estimated cost
ATC estimates that the Project will cost $75,339,000 for the Proposed Route or $92,448,000 for the Alternative Route.
