Dodge County Distribution Interconnection Project

Project overview 

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 four 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 138,000-volt 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 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 is subject to approval by the Public Service Commission of Wisconsin.  

Additional information can be found on the PSCW website, under docket number 137-CE-210.

Who decides if a project is needed and which route is chosen?

The Public Service Commission of Wisconsin is the regulatory agency with the authority to approve or deny major utility projects in Wisconsin. In this case, ATC is proposing two routes and, if the power line project is approved, the PSCW will select the final route.   

How do I provide input to the PSCW about the project?

You can provide comments to the PSCW, either electronically or in writing under docket number 137-CE-210. You may also attend a public hearing and make your statements for the PSCW record
