30-Mile 138kV New Build/69kV Rebuild

Located in Virginia and Maryland

  • Capability
    • Electric Infrastructure
  • Completion 2017–2018

Project Overview

In 2018, across Virginia and Maryland, we rebuilt 30.9 miles of 138/69kV transmission line across five separate outage windows—delivering improved electric infrastructure to utility customers.

Explore Project Details

Project Scope of Work Included:

  • Replacing 451 Wood Poles with Steel Monopoles on Foundations or Vibratory Caissons
  • Upgrading The Transmission Line from 1 to 2 Circuits
  • Installing 6 New Conductors
  • Installing 2 New OPGW Lines
  • Installing, Maintaining and Removing Erosion and Sediment Controls

Challenges and Results

Work began after one of the rainiest seasons on record, and many sections of the project area were inundated with water. Our environmental matting team laid the mats necessary to create a stable, safe working environment. In areas where matting was not feasible, we coordinated helicopter long lining to raise the new transmission wire. Despite the difficult working conditions and an accelerated work schedule, our team carefully managed environmental compliance and completed all work within tight outage phases to deliver the project on schedule and on budget.

Ultimately, our work delivered redundancy in the power supply and a more capable, reliable electric grid for the customers of our host utility without noticeably interrupting their service. We worked safely and efficiently to meet every project deadline and improve power services in these areas of Virginia and Maryland.
