Tree Trimming and Distribution Lines

Distribution Lines

5 Year Maintenance Cycle

As part of our Tree Care Program, we recently completed a 5 year cycle (2014-2018) of tree work that has significantly reduced tree related outages in the communities we serve.  2019 was the start of our second five-year program to prune trees along every mile of our distribution lines – that’s more than 24,000 miles of wires!

To deliver reliable power to you, we prune branches that could interfere with power lines. In addition to improving power reliability, we trim to provide a safe environment for the public and other utility workers. Our licensed arborists coordinate with qualified tree crews as well as local towns to make sure the job is done right. 

Hazard tree program

Most of the tree caused outages come from trees that are beyond our maintenance specifications. We focus on trees that may cause an outage before the next cycle pruning.

Pruning trees – vegetation that may be encroaching, within 8 feet to the side and 15 feet above, of the power lines. Trees that may have grown into the lines (hot spots), lifting or trimming long limbs above the lines; weak, dead, dying, diseased or structurally weak limbs.

Removing trees – dead, dying, diseased and leaning trees within 14 feet of the lines. Trees that may interfere with the power lines or have compromised root systems, structural defects, heavy lean toward the lines, or are in a poor location that may affect the power lines.
