Trimming For Reliability

How We Trim Your Trees

Ameren Missouri maintains trees on four- and six-year cycles, depending on the nature of the work and number of customers per mile on each electrical circuit. We use qualified contractors to perform the work needed to clear vegetation away from our power lines and equipment in order to keep your service reliable. Our contractors are nationally recognized as professional arboricultural companies that follow the American National Standards Institute (ANSI) pruning standards and pruning methods endorsed by the International Society of Arboriculture (ISA).

For more information, check out our Tree Trimming FAQs or request our brochure on proper tree trimming and line clearance. 

Trees near the electric power line that runs from the main power line to a home - called a service drop - are the property owner's responsibility.

If you are concerned about tree growth near your service drop, please call 800.552.7583 to request and schedule an appointment to have your service disconnected so you can have a qualified professional safely trim your trees. Only qualified line clearance tree contractors are allowed to work within 10 feet of higher voltage lines.
