Project overview
American Transmission Co. is proposing an approximately 5.3-mile, 345,000-volt electric transmission line from the Pleasant Prairie Substation in Pleasant Prairie,  Wis., to the Zion Energy Center Substation in Zion, Ill.
Project benefits
ATC studies indicate that electric customers would benefit from the project in the following ways:
Provide savings for electric utilities and their customers
- Helps relieve transmission system congestion throughout the region and enables the most efficient generators to supply power to the energy market
- Allows utilities to buy and sell power when it’s economic to do so
Improve electric system reliability, locally and regionally
- Adds an additional high-voltage line to strengthen the interstate transmission connection between Wisconsin and Illinois
- Allows for better regional access to emergency sources of power generation
Public involvement
Informational meetings, website updates and periodic mailings will provide the public with opportunities to comment on the project, monitor developments and participate in the process.
