Our tree and vegetation team works with members, the environment, and the needs of our electric system to create a balanced and proactive approach to rights-of-way maintenance. We've compiled some of the most frequent questions related to our tree and vegetation management practices.

TGR is a plant-based growth inhibitor that is applied underground directly to the area around the tree roots. It allows the tree to grow at a slower rate while improving its foliage density, color, and health. This reduces the need for tree pruning by our Vegetation Management team. TGRs are effective 3 – 5 years, depending on the tree.

Keeping trees and plants away from electrical transformers is critical in order to allow line workers safe access to equipment during an outage. Roots from vegetation can interfere with underground electrical lines and cause outages when they grow to their mature size. Plant outside the No-Grow Zone to help prevent outages and keep our crews safe.
