Eversource: We’ve Prepared, So Should You

From an Eversource announcement on Tuesday:

Eversource line and tree crews are once again ready to respond as another nor’easter moves into the region, bringing snow and high winds. With wind gusts of up to 45 mph, this storm has the potential to bring trees and tree limbs down onto power lines, causing damage to the energy system.

“We are closely monitoring the weather forecast. The expected snow can weigh down tree limbs already weakened from previous storms, leaving them susceptible to coming down in high winds and damaging our equipment,” said Eversource Vice President of Electric Operations Mike Hayhurst. “We have hundreds of employees ready to respond and will have crews prepositioned around the state before the storm hits so we’re there when customers need us to safely and quickly restore power in case of any outages.”

The company reminds customers to always stay clear of downed wires and to report them immediately to 9-1-1. They can report an outage online at, or by calling 800-286-2000. Those who signed up for the company’s two-way texting feature can send a text to report an outage and receive outage updates as they happen.

Eversource also offers the following tips on its website to help customers prepare for emergencies:
