Trees are an important natural resource that make the environment cleaner and more comfortable.
When trees and power lines come in contact with each other, power outages can occur. Tree damage and falling limbs are major reasons for these outages. In Unitil service territories, the worst tree damage results from heavy snow, ice or wind storms. However, even in fair weather, a broken limb or downed tree can cause an outage.
Unitil strives to ensure safety for all our customers and deliver reliable electric service.
Our certified arborist works with arborists and tree services throughout our service areas to maintain vegetation around our facilities and electrical sources.
Trees growing near power lines can be dangerous. Unitil schedules tree pruning in your area every five years. We use industry best management practices and techniques that minimize disease and decay entry points.
Unitil can identify significant risk trees, or hazard trees, that pose a threat to the electric system. We want to remove high-risk trees before they fall and affect service and safety. Find out how we decide to remove a tree.
Help Unitil keep power lines free of vegetation and protect your own lines from outages by planning your landscaping. A little pre-planning can make all the difference. You can find tips for your next planting project here.
Overgrown vegetation can pose safety hazards and cause avoidable power outages. To minimize the potential for outages we sometimes use herbicides. Read about our environmentally responsible practices.
Tree crews are an integral part of outage restoration during, and following, a storm. Unitil works with tree contractors to reserve resources ahead of major storms, and communicates with crews during and after restoration.
Our vegetation management program is dedicated to supporting communities and the environment. Our forestry team participates in town, community, and school tree planting and education events.
