Distribution line circuits originate at one of Duquesne Light Company's (DLC) numerous substations and transfer electricity along local streets, backyards and through forested lots to serve homes and businesses. Distribution lines and related equipment are routinely maintained to prevent tree growth and failures (falling limbs and uprooted trees) from interrupting service. Clearance requirements are based on species, growth rates, proximity to our lines and related equipment, and the importance of our facilities that would be impacted by vegetation.
- When vegetation work is required, qualified line clearance tree professionals contracted by DLC make reasonable efforts to notify property owners of impending work. Notification is done in person or through a door hanger before work is started. For questions about the work, call the line clearance professional identified on the door hanger.
- Our qualified line clearance professionals use pruning practices that are in full compliance with the American National Standards Institute (ANSI) standards and are endorsed by the International Society of Arboriculture and the Arbor Day Foundation.
- Directional Pruning is used to promote future growth away from overhead power lines. While this type of pruning is not always aesthetically pleasing, it is the best pruning practice that can be used to obtain safe clearance from our lines and equipment and to promote the health of the tree.
