Keeping customers connected to a secure, reliable source of electricity is Duquesne Light's primary goal.  That’s why we are continuing to invest in infrastructure and technology upgrades, 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.

A network of 138-kilovolt transmission lines provides power to Duquesne Light customers in north-eastern Allegheny County. With growth from new housing developments, businesses, and medical facilities, as well as projected future growth increasing the demand for energy, this network needs to be extended to enable Duquesne Light to improve current reliability and continue to deliver a reliable source of power to customers in this area in the future.  


The project schedule is currently on hold and construction is not expected to start prior to 2025.  A number of emergent regional transmission projects arose that have caused a reprioritization of company projects, which will impact the planned construction dates of the West Deer project.  The West Deer Reliability Project continues to be an important transmission infrastructure improvement initiative for our customers located in north-eastern Allegheny County.  Please check back for further updates.
