Tree Trimming

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.
