Storm Resiliency Program

Our preventative maintenance. Trees near power lines are the single greatest cause of power outages on most electric systems. To improve service reliability for customers and municipalities in our service territories, Unitil performs additional proactive tree pruning work above the normal maintenance. This preventative maintenance helps increase our electric system's resiliency, meaning our customers can rely on their power during a major storm.

Today’s right tree planted in the right place is a successful tree for the future. In the wrong place it can cause issues for everyone.

Main initiative details

The Storm Resiliency Program consists of enhanced tree pruning and increased hazard tree removal work. Crews are setting up to remove identified trees in selected areas of our Capital New Hampshire and North Central Massachusetts territories this year. Unitil has completed similar programs in the southeastern region of New Hampshire in 2012, 2014, and 2016; in the Capital Region of New Hampshire in 2013 and 2015; and in Massachusetts every year since 2014.

By consenting to this important tree work, you can help prevent power outages in your community.

To accomplish this, we wish to achieve ground-to-sky clearance that would include the removal of trees and branches growing above our electric wires as well as the incompatible trees growing underneath them that could cause future problems. Please refer to the brochure below.
