Peoria County Reliability Project
Ameren Illinois has completed and energized the Peoria County Reliability Project. The new, 5-mile transmission line in north Peoria is designed to withstand severe weather and reduce the frequency and duration of power outages by creating an additional pathway for energy to flow into the region.
About the Project
The Peoria County Reliability Project is a 138 kV transmission line that connects the existing Alta substation in Peoria County, Illinois, to the existing Pioneer substation in the city of Peoria. Ameren Illinois worked with 22 vendors and contract partners to develop the project, many of whom have offices or locations based around Peoria.
Completion Date: December 2025
Type: 138 kV transmission line
Length: 5 miles
