About Duquesne Light Company

Duquesne Light is the first and last resort for light for many residential customers in the Keystone State. The utility company provides electricity to more than 588,000 customers (90% of which are residential) in southwestern Pennsylvania via an extensive transmission and distribution system. The utility, a subsidiary of Duquesne Light Holdings (formerly DQE) acts as a generation Provider of Last Resort (POLR) for customers who do not choose an alternative supplier. A consortium led by Macquarie Infrastructure Partners controls the company's parent.


The company has 212,000 utility poles, 103,000 transformers, and more than 45,000 miles of overhead [pwer lines.

Geographic Reach

Duquesne Light provides electric service to customers in southwestern Pennsylvania, including the city of Pittsburg in a service area that covers 817 square miles in Allegheny and Beaver counties.


Duquesne Light, which has been hurt by declining margins provided by its POLR service due to unrecovered payments to PJM Interconnection generators, implemented a 2011-2013 POLR plan to yield more reliable returns, taking advantage of favorable changes in Pennsylvania law regarding POLR costs and surcharges.

In an effort to improve reliability and public safety, Duquesne Light has replaced 205 network transformers across its service region since 2002. In 2012 it replaced 29 of these network transformers and was working on replacing 42 more in 2013.

Company Background

The company was founded in 1880.
