New Hampshire
Battery backup and standby generators for second homes and year-round houses on Winnipesaukee, Squam and Sunapee, in the Upper Valley and in the White Mountains.
A lot of houses here sit empty for months. Census estimates count 17,026 seasonal homes in Carroll County and 11,207 in Belknap County, together 28,233 of the state's 65,342. When the power goes out in January, those houses have nobody inside to notice.
Boston Backup Power, a division of Boston Automations, designs and supports RoseWater Energy systems, Savant Power and Generac and Kohler standby generators for lake and mountain homes, with New Hampshire licensed electricians and gas fitters making the connections.

Storms and outages in the north country
The October 30, 2017 windstorm cost the Co-op power to 52,300 members, 65 percent of its membership and more than the 2008 ice storm, with outages in all 115 towns it serves. Statewide, NHPR called it the fourth-largest outage in New Hampshire history.
The April 4, 2024 nor'easter caused nearly 250,000 outages statewide, with Eversource's mostly in the Lakes Region and central and southern New Hampshire. The Co-op reported more than 4,200 customers out in Moultonborough, 3,600 in Alton and nearly 2,000 in Meredith.
Several utilities serve the area: Eversource, the Co-op, Liberty in the Upper Valley, and Wolfeboro's own municipal electric department, one of five left in the state.
Lake and mountain homes
The Lakes Region Planning Commission found the region's share of vacant, mostly seasonal housing was twice the state's in 2020. In Moultonborough, more than half of all houses are seasonal.
Island and shore homes are the hardest to restore. After the October 2017 windstorm, the New Hampshire Electric Cooperative restored nearly everyone within seven days except its members on Lake Winnipesaukee's islands, and the last home it reconnected was an empty cottage on Bear Island in Meredith on November 7.
About 46 percent of New Hampshire residents drink from private wells, according to the state. On a well, an outage stops the water too.
Shoreland rules and where the system goes
Within 250 feet of a lake, New Hampshire's Shoreland Water Quality Protection Act applies, and construction or excavation needs a state permit. Small projects that impact less than 1,500 square feet and add no more than 900 square feet of impervious area can qualify for a permit by notification, and local zoning still applies.
A HUB or a Savant battery inside the house adds nothing to the shoreland. A generator pad and propane tank are best placed farther back from the water, clear of roof snow, where the delivery truck can reach in winter.
RoseWater HUBs are designed for indoor installation in a garage or basement, and in a lake house garage that sits unheated all winter we confirm the spot with RoseWater's engineers. Savant's Power Storage 20 is rated down to 32 degrees Fahrenheit, so it belongs in a heated space.
Cabinet sizes and specs for each system are on the HUB20, HUB40 and 3-Phase pages.
Homes we design for in the New Hampshire Lakes and Mountains
Seasonal lake houses
Winnipesaukee, Squam and Sunapee homes that sit closed for months and need heat, freeze protection and remote checking through every outage.
Island homes
Houses on Bear Island and the other islands reached only by water, where crews arrive last and backup has to carry the house for days.
Ski and mountain homes
North Conway and White Mountain houses used on weekends, where snow load and access shape where the equipment goes.
Upper Valley homes
Hanover and New London houses near Dartmouth and Colby-Sawyer, served by Eversource, Liberty or the Co-op.

How a project runs in the New Hampshire Lakes and Mountains
Most of our lake and mountain projects are planned around when the owners are at the house. We do the site visit, the design and the paperwork, coordinate New Hampshire licensed electricians and gas fitters, the propane supplier, and any shoreland permit, and RoseWater's technicians commission a HUB on site.
Build your Power Plan
Use the Power Plan on this site or call us. You pick what has to stay on, from the network and lighting control to the well pump and the wine room.
Site visit
We look at your electrical service, the main panel and subpanels, and the rooms that could hold the cabinets. On new builds we work from the single-line diagram, riser diagrams and panel schedules.
Design with RoseWater
We register the project with RoseWater's engineering team, size the HUB and battery storage to your plan, and send you a written proposal.
Electrical tie-in
A licensed electrician connects the system at the main panel. We coordinate your electrician or bring in one we trust, along with any generator or solar partner.
Commissioning
RoseWater technicians deliver the cabinets and commission the system on site with us. Commissioning by RoseWater-trained personnel starts the three-year warranty.
Integration and support
We set up monitoring and alerts, tie the system into your home's other systems, and stay your first call for service and warranty questions.
The first step is the Power Plan. If you would rather talk it through, use the contact form or call (781) 333-8003. You can also read about our backup power installation and design services and whole-home battery backup for homes.
Standby generators in the New Hampshire Lakes and Mountains
We also install Generac and Kohler home standby generators in the New Hampshire Lakes and Mountains as an authorized partner of both brands. A licensed electrician and a licensed gas fitter make the connections, and most installs run $7,500 to $20,000.

Savant Power in the New Hampshire Lakes and Mountains
As an authorized Savant dealer, we install Savant Power in the New Hampshire Lakes and Mountains: smart modules in your panel that show and control every circuit, with Savant battery storage for backup. Savant Power Modules typically run $2,000 to $10,000. Savant battery backup runs $10,000 to more than $100,000, depending on the size of the house and what you want backed up.
Questions about backup power in the New Hampshire Lakes and Mountains
Do you work in the Lakes Region and the White Mountains?
Do you work in the Lakes Region and the White Mountains?
Yes. Wolfeboro, Meredith, Moultonborough, North Conway, Hanover, New London and the towns around them are part of our New Hampshire service area.
Our lake house is empty all winter. What should be on backup?
Our lake house is empty all winter. What should be on backup?
Heat and freeze protection, sump pumps, the well, security and the network so you can see the house. A battery covers the short outages and a propane generator the long ones.
Does a generator by the lake need a shoreland permit?
Does a generator by the lake need a shoreland permit?
Within 250 feet of the water, likely yes, though small projects can qualify for a permit by notification. A battery inside the house avoids it.
Keep the Lake House Warm
Tell us about the house, the season you use it and what has to stay on while you are away. We will recommend RoseWater, Savant Power or a standby generator and plan the work around your visits.
