24-Mile 138kV Transmission Line Rebuild

Located in Monee, Illinois

  • Capability
    • Electric Infrastructure
  • Completion 2016–2017

Project Overview

From 2016 to 2017, our host utility needed to replace an aging 138kV transmission line stretching 24 miles across northeastern Illinois. Working under a tight schedule, we were selected to rebuild and reconductor the entire line. Our crews worked efficiently to remove the line’s old wooden structures and construct new steel monopoles, reinforcing the line for decades to come.

Project Scope of Work Included:

  • Transmission
  • Installing 215 Monopoles
  • Removing 202 H Structures
  • Laying 31 Foundations
  • Managing 24 Miles of Construction Matting (Including Laying 8 Miles at Once)
  • Reconductoring Transmission Line with T2 Twist 1133 Wire

Challenges and Results

The route of the transmission line presented several challenges, including major highway crossings, lake and river crossings, and inaccessible wetlands. Our crews fought Midwestern rain and windstorms while completing the work.

Additionally, the project moved on a fast schedule, with strict outage windows limiting the first two work sessions to one month and three weeks. Relying on industry-leading work approaches and strong communication with the host utility, we carefully coordinated all project work with the help of our in-house Environmental Matting team, who laid extensive matting to make work on the line possible.

As a result, we completed all work to rebuild and bring the 138kV transmission line online over 110 days in the field. With our focus on safety in execution and continual oversight, the work was completed swiftly, efficiently, and on budget, delivering improved power services for the people of northern Illinois.
