The Knox County Connector Project includes rebuilding an existing 69-kilovolt power line from the existing Sandburg Substation, located near Galesburg, Illinois, to a future collector station near Oneida, Illinois. A majority of the line will be rebuilt on new structures and will include a second power line, referred to as a “double circuit,” which will carry both 138-kilovolt and 69-kilovolt transmission lines. A portion of the double circuit will need to be routed around the west side of Wataga. Modifications to the existing Sandburg Substation are also included in the project. Construction will begin in fall 2025 and is anticipated to be in service and providing benefits to local communities by spring 2026.
In February 2025, Ameren submitted an application to the Illinois Commerce Commission (ICC), requesting review and approval of the Project. On August 7, 2025, the ICC approved the Primary Route and issued a Certificate of Public Convenience and Necessity (CPCN) for the Project. The new transmission line is anticipated to be in service and providing benefits to the local communities by spring 2026.

With the Preferred Route approved, landowners are being contacted by the Knox County Connector Project team to discuss real estate and field studies. This important milestone in the project process is dependent upon open communication and lays the foundation for the future phases of construction.
