Pleasant Prairie-Zion Energy Center
American Transmission Co. in 2012 received approval from state regulators to construct 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. ATC studies indicate that the project will:
Provide savings for electric utilities and their customers.
- The project will help relieve transmission system congestion throughout the region and enable the most efficient generators to supply power to the energy market.
- The line will allow utilities to buy and sell power when it’s economic to do so.
Improve electric system reliability, locally and regionally.
- The project adds an additional high-voltage line to strengthen the interstate transmission connection between Wisconsin and Illinois.
- The new line will allow for better regional access to emergency sources of power generation.
