What causes power outages in New Hampshire?
Common causes include severe weather — nor'easters, ice storms, heavy snow, and thunderstorms are the leading factors. New Hampshire is one of the most heavily forested states in the nation, making tree contact with power lines especially common during storms. Winter ice accumulation on power lines and tree limbs is a major cause of widespread outages. Other factors include equipment failure, vehicle accidents, and animal interference.
How long do New Hampshire power outages typically last?
Most routine outages last 1 to 4 hours. Winter storms and ice events can cause outages lasting 12 hours to several days, particularly in rural and mountainous areas where terrain makes access difficult for repair crews. New Hampshire's mountainous terrain and heavily forested landscape can slow restoration efforts during major storms. Eversource and other utilities publish estimated restoration times on their online outage maps.
