Who Pays for Power Line Tree Trimming in Montana?

Between heavy winter snow, unpredictable spring ice storms, and powerful wind gusts that seem to scream out of nowhere, trees and power lines are a dangerous combination in Montana. When a rogue branch takes out the grid, it isn’t just about sitting in the dark; it’s about preventing catastrophic wildfires, blown transformers, and lethal safety hazards across the Big Sky State.

The Multi-Million Dollar Battle to Keep Montana’s Lights On

Every year, companies like NorthWestern Energy, Montana-Dakota Utilities (MDU), and local electric cooperatives spend millions trimming branches and managing vegetation. But a massive point of confusion for local homeowners remains a simple one: Whose job is it to actually cut the tree? The answer depends entirely on exactly which wire the branch is touching.

Utility Companies Handle High-Voltage Lines and Public Rights-of-Way

If a tree is threatening a high-voltage transmission line or a neighborhood distribution line, the main wires running down your street or alleyway, the utility company handles it. If the tree sits within a legal right-of-way or utility easement, it is their financial and legal responsibility. Utilities contract specialized, certified arborists who are trained to work around high-voltage setups, running year-round programs to inspect, trim, and remove hazardous timber.

The Surprise Rule: Homeowners Usually Own the "Service Drop" Line

Here is the curveball that catches most Montana property owners off guard: If a tree on your private property interferes with the wire running directly from the pole to your house (the "service drop"), it is usually your responsibility. If a branch is rubbing against the wire feeding electricity straight into your breaker box, you have to hire a private, insured tree service to fix it. The utility company will generally not clear this line for free, as it sits on private property to serve a single home.

DIY Trimming Near Live Power Lines is Never Worth the Risk

Never, under any circumstances, attempt to trim a tree touching or hanging near a power line yourself. Electricity can arc through tree limbs, metal ladders, chainsaws, and even the ground under certain conditions. Even experienced homeowners with chainsaws can seriously injure themselves around energized lines. If you notice a dangerous tree situation, the safest thing to do is contact your local utility provider and have trained professionals assess it.
