VEGETATION MANAGEMENT FOR TRANSMISSION

An important part of delivering safe and reliable electric service is maintaining transmission rights-of-way, the property below and next to Oncor's high-voltage transmission lines. Routine vegetation management helps avoid high maintenance and repair costs, and prevents hazardous electrical clearance violations by allowing access to the lines for routine maintenance. Tree trimming and mowing to control growth are essential to long-term grid reliability.

Our utility easements typically grant Oncor the right to access property for inspection, repair and maintenance of transmission lines, including the right to remove trees and other obstructions. In determining what trees or other vegetation need attention, Oncor applies the National Electric Safety Code for determining minimum alternative vertical and horizontal clearances required to maintain a safe distance between power lines and roads, rooftops and bodies of water. Additionally, we employ a team of biologists that conduct reviews to ensure the safety and preservation of endangered species and their habitats.
