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 our nearly 600,000 customers in Allegheny and Beaver counties. As part of our commitment, we are investing more than $2.6 billion in infrastructure and technology upgrades between 2010 and 2020. These investments will do more than keep your lights on, they'll help keep your life on.
