Tree damage and falling limbs — usually due to heavy snow, ice or wind — are the primary causes of power outages. Our certified arborists work with commercial and municipal arborists and tree services throughout our service areas to maintain vegetation around our facilities and electrical sources. This work has had a considerable effect on our ability to more reliably keep your power on. As a customer, there are also steps you can take to help keep our lines branch-free. Together, we can help prevent power outages from trees. Unitil’s Preventative Tree Maintenance Trees growing near power lines can be dangerous. Unitil schedules maintenance tree pruning in your area every five years. We use industry best management practices and techniques that minimize disease and decay entry points.
