The Connecticut Public Utility Regulatory Authority recently required Eversource to establish a toll-free phone number for residents to call with questions about tree work. The toll-free number at Eversource is 844-275-3302. Lyme residents can call this number with concerns about trees and branches near their power lines; questions about tree work that is being planned in their neighborhood; and concerns about how tree pruning and trimming is done in Lyme.
