Plant wisely for safer, more reliable power
Trees and power lines can sway when subjected to high winds. And in hot weather when carrying heavy loads or in cold weather when covered with ice, transmission lines can sag as much as 25 feet below their normal operating height.
Sags and sways (see video) can lead to unanticipated proximity to trees and other plants that might seem to be well out of the way. All it takes is a brief instant when a tree and a line get an inch too close. A flash-over results and an outage ensues.
That's why it's so important to think ahead and choose wisely whenever you plant in a transmission right of way.
The general rule is: nothing that is, or will grow to be, more than 15 feet high.
Avoid woody plants that, while low-growing, can impede access for maintenance and slow down repairs.
TVA is here to help you make good choices. We have prepared a list of suggested trees and shrubs that are compatible with transmission rights of way. But because plants grow differently depending on where they are planted, we encourage you to contact your transmission right of way specialist before planting anything in a transmission right of way or any time you have questions about what's appropriate for your transmission easement.
