You can help ensure reliable electric service – and minimize potential unsafe situations – by following the “right tree in the right place” approach when planning landscaping around your residence, business or in your community. Trees grow to different mature heights and widths. Before you grab a shovel, find out how high and wide your tree may grow, and size up the area where you plan to plant it.

The diagram below shows where trees should be planted when being installed next to energized electrical distribution equipment. Consult the list of utility-compatible shrubs and trees below for compatible low-growing trees that can safely be planted in the “red zone” because their mature height is less than 25 feet.

When planning to plant in or near our transmission line corridors, the distance between your tree and overhead power lines should significantly increase.  Please call us at 888-393-7100. DLC will contact you to discuss your work plan.

Please do not plant tall-growing trees under or near power lines. Inappropriately planted trees that interfere with overhead power lines or electrical equipment may be removed by Duquesne Light’s qualified line clearance professionals or, at a minimum, will require future pruning and have potential for disfigurement.

Remember: Right Tree, Right Place! A healthy, properly placed tree is a safe tree.
