New Hampshire Lakes and Mountains Backup Power in New London

Whole-home battery backup and standby generators for New London, from the hilltop town center to the shores of Lake Sunapee and Pleasant Lake.

Build Your Power Plan

New London sits on a hilltop between three lakes, with Lake Sunapee along its western border, Little Sunapee to the north of the center and Pleasant Lake to the east. It is home to Colby-Sawyer College, and about 684 of its 2,417 housing units are seasonal.

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 New London

In the December 29 and 30, 2025 ice storm, tree limbs caused three larger outages in New London affecting 50 to 100 people each, plus several smaller ones around Lake Sunapee. Some residents were still out on Tuesday.

During that storm the town asked people to stay home unless absolutely necessary, opened a conference room at the Town Offices as a warming station, and the fire department answered more than 50 calls for trees on lines, alarms and medical help. Next door in Sunapee, the fire station and dispatch center ran on backup power.

Who supplies the power

Eversource serves New London, which is not in the Co-op's, Liberty's or Unitil's territory. A solar and battery system here is interconnected through Eversource New Hampshire.

Which system fits a New London home?

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

RoseWater Energy

For a large Lake Sunapee house with lighting control, AV, networking and security, often closed for part of the year, a RoseWater HUB keeps it running with zero transfer time and lets you check on it remotely.

Whole-home battery backup with zero transfer time and power conditioning, for large homes where nothing can blink. Most projects run $125,000 to $1,000,000.

Savant Power

For a smaller New London house or a lake cottage, Savant Power keeps the heat and the essentials on from Savant Power Storage in a heated room, with the relay modules in the existing panel.

Relay modules in your existing panel and Savant Power Storage batteries, so you choose which circuits get backup power and see your usage in the Savant app. Modules typically run $2,000 to $10,000, and battery backup $10,000 to more than $100,000.

About Savant Power

Standby generator

A propane standby generator covers a multi-day ice storm on its own, or keeps a battery charged through one.

A Generac or Kohler standby generator on natural gas or propane that starts on its own when the power goes out. Most installs run $7,500 to $20,000.

About standby generators

Where the equipment goes in New London

On Lake Sunapee, Little Sunapee or Pleasant Lake, the first 250 feet back from the water is protected shoreland under state law, and construction there needs a permit. A HUB or a battery inside the house adds nothing to the shoreland, and a generator pad goes farther back where the lot allows.

In the 2025 storm it was tree limbs scattered across many roads, so the outages were many and small, each one waiting its turn for a crew.

Permits in New London

We have not found a New London permit page for generators or batteries. Within 250 feet of the lakes, New Hampshire's shoreland law requires a state permit for construction or excavation, and smaller projects can qualify for a permit by notification.

FAQ

Questions about backup power in New London

The town opened a warming station in the 2025 ice storm. How do we avoid needing it?

The town opened a warming station in the 2025 ice storm. How do we avoid needing it?

Keep the heating system on backup. Even a propane or oil boiler needs electricity for its burner and pumps. A battery sized for the heat, or a generator, keeps the house warm through the outage.

We are on Lake Sunapee. Do we need a shoreland permit for a generator?

We are on Lake Sunapee. Do we need a shoreland permit for a generator?

If the pad is within 250 feet of the water, likely yes, though small projects can qualify for a permit by notification. Placing it farther back, or using a battery inside, avoids most of it.

Is New London too far north for you?

Is New London too far north for you?

No. New London is part of our New Hampshire Lakes and Mountains area, and we coordinate New Hampshire licensed trades for the installation.
