TCEC works with Riggs Tree Service for tree trimming. They use a method called directional pruning. Directional pruning makes cuts where the tree will grow away from the power line rather than into it. It meets the American National Standards Institute A300 standard. This is a generally accepted industry standard for tree care.
Before trimming trees near a residence, Riggs attempts to contact the member by knocking on the door. If no one answers, they leave a door hanger letting them know the maintenance occurred. TCEC has a right and a responsibility to trim trees in its rights-of-way to keep your power safe and reliable.
