Duquesne Light Company, headquartered in Pittsburgh, announced recently that is has completed Phase 3A of its multi-phase Brunot Island-Crescent Transmission Reliability project.

The project, part of a larger effort by DLC to modernize a network of century-old transmission lines, replaced some of the company’s oldest infrastructure along a 14.5 mile stretch from its substation in Crescent Township to its substation on Brunot Island along the Ohio River.

DLC said the project is part of its work to modernize the network of 138kV transmission lines serving Moon Township, Robinson Township, Kennedy Township, McKees Rocks and the city of Pittsburgh. The modernization efforts will improve the quality of service, the company said, as well as allow the company to deliver safe, reliable and affordable power to consumers and businesses in the area.

“Thanks to the efforts of everyone involved. This project will ensure this transmission line is healthy and prepared to meet our customers’ current and future electrical demands,” Jason A. Harchick, DLC’s director of grid optimization and asset management, said.

Construction for the multi-phased project started in December 2021. Work is expected to be finalized by spring 2027. The initial part of Phase 3A was completed in November 2023, and involved replacing six lattice structures with self-supporting steel monopoles anchored to concrete bases.

The project is one of seven Transmission & Distribution Projects listed on the company’s reliability project page on its website.

“We are committed to investing in infrastructure and technology that enable us to meet the increasing demand for energy in the region,” DLC said on its website. “A major part of that commitment is ensuring that our electrical infrastructure — the wires, transformers, substations, poles and other equipment that make up the company’s transmission and distribution system – delivers power safely and reliably to your home or business.”
