As Eversource adapts to working during the COVID-19 pandemic, a “No Knock, No Hang” tree work permissions policy is being implemented. Trees are the number one cause of power outages. Licensed arborists and tree contractors are obtaining customer consent for any tree work on private property using phone calls, e-mails or texts, rather than knocking on doors or leaving behind permission paperwork. In 2020, Eversource is investing more than $83 million in tree trimming and tree removal in Connecticut. Eversource collaborates with the tree warden in each town where work is done to balance the need for providing reliable electricity while maintaining aesthetics.
