Ameren Transmission, in collaboration with the City of Highland, is proposing the Sursee-Aviston Transmission Project to improve energy reliability for local customers in Madison, Clinton and St. Clair counties. This project includes the construction of a new approximately 15-mile 138 kV transmission line to connect the existing Aviston substation in Clinton County to the new Sursee substation to be located west of Highland in Madison County. It includes upgrading the Aviston substation and will strengthen our grid by creating an additional pathway of energy.
New projects, like the Sursee-Aviston Transmission Project, help us serve, support and invest in our local and regional communities’ future energy needs.
Our goal is to have this project completed and providing reliable energy to the community by the end of 2025.
Please click the link below to see a map of the preliminary route alternatives that were presented to the public at the December 2022 open houses. These route alternatives were defined based on the potential route segments presented to the public at the October 2022 open houses. The next step will be to narrow these route alternatives down and name one “preferred route” and “alternate route(s)” to present in the application to the Illinois Commerce Commission in the spring 2023.
The Sursee-Aviston Transmission Project will benefit the local area by:
We realize a large infrastructure project such as this may be challenging for our customers, and we are committed to working with the communities along the route to make the process as smooth as possible. Ameren Transmission is developing the Sursee-Aviston Transmission Project in a collaborative manner with landowners, community officials and agencies to develop a constructible route that minimizes impacts. To that end, we have designed a public engagement program to be responsive and considerate of public feedback.
We have a designated project hotline and email address that the public can use to get in touch with members of our project team. Download the Sursee-Aviston Fact Sheet (PDF). Have a question for our team? Please contact us using one of the methods below.
