To deliver safe and reliable electric service, we must
keep trees pruned a safe distance from power lines because many power outages
are caused when tree branches fall onto power lines.
Our tree management program includes routine pruning,
storm hardening, maintenance and rights-of-way work. The work our licensed,
professional foresters and contract tree pruning experts do is for public
safety and the safety and health of the trees.
Our tree pruning program
consists of four categories:
of trees along our primary distribution lines in residential areas generally
need pruning every two to five years. Our tree pruning contractor prunes every
tree that could potentially come in contact with power lines or other
electrical equipment. This minimizes outages caused by trees and tree branches
and improves the reliability and safety of your electric service.
areas along our system are impacted more by storms than other areas. These are
areas that have large tree growth well above the electric system and require
more than routine pruning. Our storm hardening project focuses on lines most
susceptible to damage from trees during a storm to keep them clear of trees
that could cause outages.
on the system goes beyond routine tree pruning. It includes assisting in the
restoration efforts after a storm as well as providing assistance to public and
private property owners with the removal of hazardous trees near power lines.
rights-of-way, we generally mow the land beneath the high-voltage lines every
four to five years to prevent trees and other vegetation from growing into the
high-voltage transmission and distribution lines.
When trying to decide what type of tree to plant and
where to plant it, consider the location of overhead utility lines when making
your choice. Remember, each tree species grows in a different way and will
reach different heights, so keep in mind what the tree will look like when it
reaches maturity when deciding where to plant it.
Tall trees, such as Maple, Sycamore, Oak, Spruce and
Pine, should be planted more than 50
feet away from wires.
Medium trees that grow to a height of 40 feet or less,
such as Birch, Serviceberry, and Honey Locust, should be planted at least 20 feet from power lines.
Small trees that grow to no more than 25 feet in height,
such as Dogwood, Flowering Cherry, Crabapple, Purple Leaf Plum and Japanese Red
Maple, are recommended for areas close to power lines.
