How Duquesne Light plans to replace 100-year-old electrical infrastructure

PITTSBURGH — When Duquesne Light Co. completes its extensive work along the Brunot Island-Crescent Transmission Line corridor by the end of 2027, it will not only have replaced transmission towers and infrastructure that in some cases goes back to 1915, but will also increase the reliability of electricity to large parts of Pittsburgh and along the western edge of the Ohio River north of the city.

“This is some of the oldest areas of our right-of-way,” said Jason Hartle, senior program manager of the Pittsburgh-based utility and project manager of what Duquesne Light is calling the BI-Crescent Project. The project is expected to cost between $130 million and $160 million.

The 138-kilovolt transmission lines are key to powering the Pittsburgh region. They run from a substation in Crescent Township down to another substation on Brunot Island. That’s from the Beaver County line through Moon Township, Robinson Township, Kennedy Township and McKees Rocks to the island in the Ohio River. The utility owns and operates the lines and substations, although they are often located in municipal and other hard-to-reach areas.
