Illinois Valley Reliability Project
Ameren Transmission is proposing the Illinois Valley Reliability Project to improve energy reliability for communities in Bureau and LaSalle counties. The Project includes constructing a new, approximately 23-mile, 138-kilovolt transmission line, upgrading the existing Princeton substation, and building a new switching station called Lima located near Peru. The new transmission line will connect the Princeton substation to the new Lima switching station.
About the Project

The Illinois Valley Reliability Project will improve energy reliability and resiliency for local homes and businesses, upgrade existing infrastructure, and support long-term economic growth in the region. Our goal is to have the Project in service and providing benefits to local communities in late 2029.

Public & Stakeholder Involvement
Ameren Transmission will undertake a robust stakeholder and community engagement process as we prepare to apply for a Certificate of Public Convenience and Necessity (CPCN) from the Illinois Commerce Commission (ICC). Community leaders and members of the public are encouraged to get involved in several ways throughout the routing process, including attending in-person open houses, viewing virtual open houses, and filling out comment forms at meetings and online on the interactive map.
Open Houses - Please Join Us

We will hold three rounds of in-person and virtual public open houses to introduce the study area, potential route segments, and the project needs and benefits. During the in-person open houses, subject matter experts from different departments of Ameren (such as engineering, real estate, siting, environmental, safety and construction) will be available to answer questions about the Project and collect public feedback. This feedback will be carefully considered by our siting team as they work to design a constructible route for the line.

The first round of open houses will be held on August 5 in Princeton and on August 6 in Peru. Both sessions will include the same information, with no formal presentation. Input collected on the route segments shown during these open houses will be factored into identifying potential route alternatives in the study area. An interactive map is available for feedback and comments Aug. 4-15, 2025. Additional open houses will be held in September and November 2025.
