Montgomery-Callaway Connector Project
The Project includes approximately 30 miles of double-circuit, 345-kilovolt transmission line in Montgomery and Callaway counties. The proposed transmission line will connect the existing Burns substation in Callaway County to the existing Montgomery substation in Montgomery County. An in-depth routing study was completed in 2025. Ameren Missouri has also gathered input from landowners, community members, interested agencies and local officials. The project schedule is now being reevaluated. 
About the Project

The regional grid operator, Midcontinent Independent System Operator (MISO), identified the need for this project to support new, third-party energy sources. As the incumbent energy provider, federal regulation requires Ameren Missouri to develop grid infrastructure projects that fulfill these needs.
