At Duquesne Light Company (DLC), we like to think we’re larger than light. For more than a century, we have been working around the clock to deliver a safe and reliable supply of electricity to more than 600,000 customers in Allegheny and Beaver counties. As part of our commitment, we invested more than $3.1 billion in infrastructure and technology upgrades between 2011 and 2021. These investments will do more than keep your lights on, they'll help keep your life on.


Whether it’s helping fund or providing volunteers for an important neighborhood project, we do a lot of things for the community that are a lot larger than light.
