PROJECT STATUS: The Public Service Commission of Wisconsin gave verbal approval in September 2025.
Project Description
ATC plans to build electric facilities in northwest Dodge and northeast Columbia counties. The project includes building a new substation, expanding an existing substation, rebuilding an existing power line, constructing a new double circuit power line, making minor upgrades to five substations, and rerouting an existing power line around another substation.
This project includes:
- Building a new substation in the town of Trenton, just northwest of the city of Beaver Dam in Dodge County, that will be called the Manhattan Substation.
- Expanding the existing North Randolph Substation in the town of Randolph, Columbia County.
- Rebuilding approximately 15-miles of existing 138-kilovolt line from the North Randolph Substation to the new Manhattan Substation, where the line will be segmented to the North Beaver Dam Substation.
- Constructing an approximately 15-mile, new double circuit 138-kV power line from the North Randolph Substation to the Manhattan Substation.
- Making minor modifications at the North Beaver Dam, Green Lake, Staff, Metomen and Academy substations, and rerouting existing power line around the North Randolph Substation.
Project Need
This project is needed to support anticipated load growth in the Beaver Dam area. Load growth is good for the economy and benefits ratepayers. Robust infrastructure helps drive economic development and can serve as a magnet for attracting future growth.
The project was given verbal approval by the Public Service Commission of Wisconsin in September 2025. The PSCW also approved ATC’s preferred route (see Approved Route Map at right). We are awaiting a formal, written order from the PSCW before beginning pre-construction activities later this year.
Additional information can be found on the PSCW website, under docket number 137-CE-210.
