Duquesne Light is the first and last resort for light for many in the Keystone State. The company, founded in 1880, provides electricity to more than 500,000 customers in southwestern Pennsylvania over its 17,000-mile 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 and Diversified Utilities and Energy Trust (DUET) controls the company's parent.
In 2010 DUET announced plans to sell its 29% in the company, its only investment outside of Australia, to a Government of Singapore entity, in order to free up cash to reinvest in Australian businesses.
Duquesne Light, which has been hurt by declining margins provided by its POLR service due to unrecovered payments to PJM Interconnection generators, has a 2011-2013 POLR plan which promises to yield more reliable returns, thanks to changes in Pennsylvania law regarding POLR costs and surcharges.
Richard Riazzi was named president and CEO of Duquesne Light in 2010. Riazzi previously was CEO and General Manager of the Chelan County Public Utility District in the state of Washington. He replaced interim CEO Andrew Chapman.
