PROJECT STATUS: Submitted application to the Public Service Commission of Wisconsin in December 2024.
Project overview
- Kieler Substation rebuild and relocation – Proposed by Alliant Energy, this rebuilt and relocated substation would serve anticipated area electric load growth and would also support power demand from a new Alliant Energy customer.
- ATC distribution interconnection facilities – ATC would install new substation equipment, as well as build two new power lines to connect Alliant Energy’s new Kieler Substation and an Alliant Energy customer-owned substation to the electric grid.
Project description
ATC is proposing to build distribution interconnection facilities and make added electric grid upgrades in Grant County. The facilities would connect the new Alliant Energy Kieler Substation and a new Alliant Energy customer-owned substation to the electric grid. The preliminary location for the new Kieler Substation is on Line Road in the town of Paris. This project was requested by ATC’s customer, Alliant Energy, through two Load Interconnection Requests.
This project includes:
- Building one power line that would connect the new Kieler Substation to a second new substation to the north and modifying the existing Y-204 line and extending it to the new Kieler Substation.
- Constructing a second power line that would connect the new Kieler Substation in the town of Paris with an existing power line in Cuba City.
- These two, new 69,000-volt lines would total about 10 miles and would be located in the towns of Jamestown, Paris, Hazel Green and Smelser, as well as the city of Cuba City.
- Installing and locating new substation equipment on Alliant Energy’s property to support Alliant Energy’s new Kieler Substation. This will include a new control building, circuit breakers, steel structures, electrical bus and capacitor banks.
The estimated cost of the project is anticipated to be approximately $38 million.
Project need
The project is needed to address anticipated economic and general load growth in the Kieler/Dickeyville area of Grant County and solve bridging limitations for the new and existing loads in the area. ATC is proposing this project at the request of its customer, Alliant Energy.
The ATC project is subject to approval by the Public Service Commission of Wisconsin.
Additional information about the proposed ATC project can be found on the Public Service Commission of Wisconsin website under docket number 137-CE-214.
