American Transmission Co. plans to construct a new 6.6-mile 138,000-volt high-voltage transmission line to ensure electric reliability in Sheboygan County and the surrounding area. The electric modifications for the project include:
- Constructing a new 6.6-mile single circuit 138-kV line from the Howards Grove Substation near the village of Howards Grove to the Erdman Substation in the city of Sheboygan.
- Expanding the Howards Grove Substation to a 4-position ring bus to improve reliability performance and operational flexibility.
- Substation modifications at the Erdman Substation to accommodate the new line.
Need for the project
The need for the new transmission line is driven by nearby energy demand, system limitations related to maintenance and other outage conditions, and local changes in energy generation. The estimated cost for this project is $28.5 million. Additional information can be found on the Public Service Commission of Wisconsin website, under docket number 137-CE-195.
