Application Summary
Overview
American Transmission Company (ATC or applicant) is seeking approval to expand the existing 138 Kilovolt (kV) North Randolph Substation in the Town of Randolph and to construct a new 138 kV substation near the City of Beaver Dam (Manhattan Substation). The ATC Project includes a new double-circuit 138 kV line to be constructed from the North Randolph Substation to the Manhattan Substation. Additionally, the existing single-circuit 138 kV line (X-47) would be rebuilt from the North Randolph Substation to the new Manhattan Substation, where X-47 would be segmented to the North Beaver Dam Substation. The ATC project would include the rerouting of the existing transmission lines around the North Randolph Substation and minor modifications at the substation remote ends (substations include North Beaver Dam, Green Lake, Staff, and Academy). The Proposed Route would be approximately 18.7 miles in total length (including relocating existing lines and tie lines), including a total of 307.1 acres of Right-of-Way (ROW).
The Proposed Route would be built on both new and existing ROW. The single-circuit rebuild (X-47) would predominately run along the existing ROW, with the double-circuit requiring new ROW, overlapping slightly with the existing ROW. The Proposed Route was designed to follow existing utility easements and transportation corridors as practicable, and approximately 32.7 percent of the ROW is shared.
The Alternative Route would split the X-47 rebuild from the new double-circuit 138 kV line in several locations. The Alternative Route would be approximately 29.6 miles in total length (including relocating existing lines and tie lines), including a total of 314.1 acres of ROW. The Alternative rebuild Route would rebuild X-47 generally along its existing ROW, and the proposed double-circuit line would also follow existing utility easements and transportation corridors, resulting in approximately 38.6 percent of shared ROW.
Applicant stated need
The project is needed to reliably serve a load interconnection request by Wisconsin Power and Light Co (WPL) to serve a new large load addition in the Beaver Dam area.
Estimated cost
The applicant stated that the estimated project cost would be approximately $109.1 million if the proposed route is selected and approximately $198.6 million if the alternative route is selected.
Project location
The project would be located in Dodge and Columbia Counties, Wisconsin.
Proposed schedule
- The applicant submitted the application to the Commission in November 2024.
- If approved, the applicant anticipates construction for this project to begin in January 2026 with an estimated completion date of July 2027.
