Keeping customers connected to a secure, reliable source of electricity is Duquesne Light's primary goal. 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.

That’s why we are investing more than $2.9 billion in infrastructure and technology upgrades between 2011 and 2021, reinforcing our commitment to maintaining, and improving, the region’s critical transmission and distribution system. Our dedication to improving the way energy is delivered is just one of the many ways we are working to become your next generation energy company.
