American Transmission Co. projects

Project website for a Wisconsin-based company that owns and operates the high-voltage electric transmission system that powers communities in portions of the Upper Midwest.


Project overview

American Transmission Co. is proposing new and upgraded electric transmission facilities to keep pace with growing electricity demand in southern Walworth and western Kenosha counties in Wisconsin. The project involves:

  • Construction of a new 138,000-volt transmission line of approximately 25 miles, stretching from the existing North Lake Geneva Substation in southern Walworth County to the existing Spring Valley Substation in western Kenosha County.
  • Construction of a new 138- and 69-kV substation on an ATC-owned parcel along Hwy. 50 in the Town of Wheatland, or at an existing substation site called Richmond Road in the Town of Randall.
  • Construction of a new 69-kV transmission line to connect the new substation to the existing Twin Lakes Substation in Twin Lakes.
  • Depending on the route and substation site, other power line modifications may be needed.

Need for the project

Studies indicate that the estimated $72 to $91 million project would deliver benefits to the area by strengthening the electric system to meet the growing use of electricity. The area electric transmission system is vulnerable to low voltages and power outages and will no longer adequately support the lower-voltage distribution system. This project will provide system redundancy and allow for maintenance outages when repairs are needed.
