For more than 130 years, Duquesne Light Company has remained committed to providing safe, reliable electric service to customers across Allegheny and Beaver counties. We are committed to investing in infrastructure and technology that enable us to meet the increasing demand for energy in the region.  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.

As a result, from time to time we must repair and enhance our system. While our infrastructure has served customers well for decades, various components are nearing the end of their useful operating lives. We proactively replace that equipment in order to maintain the levels of service and reliability that you've come to expect from Duquesne Light, and to ensure that the region will be able to meet future energy demands.

 You can link below to a variety of information on specific infrastructure improvement projects taking place across our service territory.
