Hanover is a college town on the Connecticut River, home to Dartmouth and the Army Corps of Engineers' Cold Regions Research and Engineering Laboratory. Three different utilities list parts of the town, and one tree on the right line can take down downtown and the hospital corridor at once.

Boston Backup Power is a division of Boston Automations in Norwood. We design and install RoseWater Energy systems, Savant Power and Generac and Kohler standby generators, and licensed electricians and gas fitters make the connections.

Storms and outages in Hanover

On April 28, 2025, a wind-felled tree on lines near Route 120 knocked out more than 4,600 Grafton County customers for about an hour and a half. Downtown Hanover and the Route 120 corridor went dark, Dartmouth-Hitchcock Medical Center canceled appointments and downtown businesses closed.

On April 16, 2018, ice and wind left about 2,100 Liberty customers out, half of them in Lebanon and Hanover. A December 17, 2022 snowstorm left about 680 Liberty customers without power at 11 p.m., mostly in the Hanover and Lebanon area.

Who supplies the power

Eversource, Liberty and the New Hampshire Electric Cooperative all list Hanover, the Co-op for limited areas only. Which one serves your house is on your bill, and that utility reviews any solar and battery interconnection.

Which system fits a Hanover home?

We install all three, so we can recommend the one that suits the house and the budget.

About standby generators

Where the equipment goes in Hanover

More than three quarters of Hanover's residents live in the compact area in the southwest corner of town, where lots are smaller and a battery inside the house is often easier than a generator outside. The rest of town, including Etna and Hanover Center, is rural, with room for a generator pad well clear of the house.

About 320 of Hanover's housing units are seasonal. For a house that sits empty for stretches, a system that runs and reports on its own matters.

FAQ

Questions about backup power in Hanover

Three utilities serve Hanover. Does that affect the system?

Three utilities serve Hanover. Does that affect the system?

Not the equipment. It affects who restores your line and who reviews a solar and battery hookup. Check your electric bill to see whether you are on Eversource, Liberty or the Co-op.
