Standby generators and home battery backup for Windham, New Hampshire, a few miles over the Massachusetts line off I-93.
Get a Generator QuoteWindham is served by two different electric utilities, Eversource and Liberty, which means neighbors on different streets can wait very different lengths of time for the lights to come back.
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 Windham
When Sandy came through on October 29, 2012, Liberty had 564 of its 1,075 Windham customers out with no estimated time of return, and only 27 PSNH customers in town still had power at 7 p.m. Three days later, 832 PSNH customers, 17.1 percent, were still out, and one resident's circuit had 42 trouble spots.
High winds on February 8, 2019 left 546 Liberty customers in town without power at 4:15 p.m. In the April 4, 2024 nor'easter, Eversource reported 800 to 1,500 customers out in Windham.
Who supplies the power
Both Eversource and Liberty list Windham in their New Hampshire territories. In 2012 Patch counted 4,879 PSNH customers in town, now Eversource, and 1,075 on Liberty. Your bill tells you which one you have, and that is who handles a solar and battery interconnection.
Which system fits a Windham home?
We install all three, so we can recommend the one that suits the house and the budget.
RoseWater Energy
In a Windham house with a big network and AV, a RoseWater HUB takes the blink out of the outage whichever of the two utilities serves the street.
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
Savant Power suits a newer Windham subdivision house, with relay modules in a modern panel and the Savant app showing which circuits are on during an outage.
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.
Where the equipment goes in Windham
Windham mixes suburban subdivisions with rural open space, and about 5,058 of its 5,589 housing units are single-family houses. Most have room for a generator pad clear of windows and doors.
About 151 units are seasonal, so a few Windham houses sit empty part of the year. For those, a system that starts and runs on its own matters more.
Permits in Windham
We have not found a Windham permit form specific to generators. The town publishes a general residential building permit application through Community Development, and a New Hampshire licensed electrician and gas fitter pull the trade permits.

Questions about backup power in Windham
Does it matter whether we are on Eversource or Liberty?
Does it matter whether we are on Eversource or Liberty?
Not for a generator, which runs either way. It matters for who restores your street and who reviews a solar and battery interconnection. Check your electric bill.
How long would a generator run in an outage like Sandy?
How long would a generator run in an outage like Sandy?
As long as the fuel lasts. On natural gas that is open-ended. On propane, the tank size and the load decide it, and we size the tank for several days.
Is Windham in your service area?
Is Windham in your service area?
Yes. Windham is a short drive over the line on I-93, and southern New Hampshire is part of our regular area.
We are on a cul-de-sac in a newer subdivision. Is there room for a generator?
We are on a cul-de-sac in a newer subdivision. Is there room for a generator?
Usually. The manufacturers' clearances from windows, doors and vents decide the spot more than the size of the lot does. We check the side and rear yards on the site visit.
