Idaho Falls Power is responsible for trimming trees, branches or other obstructions that interfere primary power lines, which are those running from power pole to power pole. Idaho Falls Power contracts with a professional tree service company to trim trees around primary lines year-round. Doing this has drastically reduced the number of tree-related outages.
The secondary line, which runs from the pole (and transformer) to a home or business, is the responsibility of the customer or property owner. IFP will temporarily cut power to the property to allow property owners, or their contractor, to safely trim or remove any tree or limb in contact with the secondary line. This is provided during business hours and there is no charge.

We trim trees, branches and other obstructions that interfere with the operations or maintenance of primary electric lines or equipment. Primary electric lines are those that run from pole to pole.
The customer or building owner is responsible to clear the power lines that run from the transformer to the home or building. Idaho Falls Power will disconnect and reconnect these lines at no charge while any trimming work is being done.
Idaho Falls Power now contracts with a professional tree service company to trim trees around primary lines year-round. Doing this has drastically reduced the number of tree-related outages.
