One hundred years ago, lineworkers constructed steel lattice towers with horse-drawn wagons, transport carts, pulley systems and their own bare hands. Today, on the farmland stretching across southwestern Pennsylvania that has now transformed into an urban area, lineworkers are swapping out the historic structures with 99 steel pole monopoles.Pittsburgh, Pennsylvania-based Duquesne Light Company (DLC) is modernizing the overhead line to improve the reliability and resiliency of its transmission system, which is critical to providing safe and reliable electricity to the company’s customers. DLC is committed to investing in critical infrastructure and new technologies to meet the increasing and evolving need for energy throughout its two-county service territory, which encompasses more than 600,000 customers. With the growing focus on electrification and renewable generation, this project will also help to lay the backbone for future grid changes in the Pittsburgh region.
Modernizing the Line
Project in Progress
Beyond monitoring and tracking the progress on the project, DLC is also making sure it is in alignment with its budget. The company and its engineering contractor performed testing and site preparation to ensure it understands the existing site conditions. That way, engineers can identify any risks before they pose challenges on the project. To keep the job on track, DLC has many team meetings and convenes frequently virtually or in-person.
