Get a Savant Quote

Falmouth has two coastlines, Buzzards Bay on one side and Vineyard Sound on the other, and a lot of its homes are lived in all year. When the grid goes down here it tends to go down for most of the town at once, and it can stay down for days while crews work through the trees.

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 Falmouth

In the blizzard of February 23, 2026, Falmouth had more customers out than any other town on MEMA's list. At 12:30 p.m., 22,885 Falmouth customers were out, which MEMA put at 90 percent of the town. Two days later Eversource reported about 68 percent of Falmouth properties still without power, with 142 crews working in town, and on Thursday morning nearly 10,000 Falmouth customers were still dark. Falmouth High School could not open as a warming center because its own generator failed.

Smaller storms do it too. In the third March nor'easter of 2018, 55 percent of Falmouth was out by 9 p.m. In the October 2019 bomb cyclone, the town manager said Falmouth could not clear trees tangled in wires until Eversource arrived, and roads around Woods Hole stayed closed until utility crews got there.

Who supplies the power

Eversource supplies Falmouth. During the February 2026 blizzard the town posted Eversource's own restoration figures and crew counts on its website, and it had to bring in a generator to keep the water treatment plant running. Any battery or solar interconnection on a Falmouth house is filed with Eversource.

Which system fits a Falmouth home?

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

Savant Power

For a year-round Falmouth house that wants to ride through a multi-day outage on the circuits that matter, Savant Power puts relay modules in your existing panel and adds Savant battery storage. You decide what stays on from the app.

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 RoseWater Energy

Standby generator

If the goal is to keep heat, water and the refrigerator going for as long as a Falmouth outage lasts, a standby generator on natural gas or propane is the most direct answer, and a battery can be added later.

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.

Where the equipment goes in Falmouth

In Woods Hole, waves have topped the seawall at Waterfront Park in heavy storms and run onto Water Street, and the science institutions there have commissioned their own flood study. If your house is near the harbor or the Sound, keep batteries and generators off the lowest floor and out of the path of surge.

Most Falmouth houses inland of the shore have room in a garage or a dry basement for a battery cabinet, and a side yard for a generator pad that meets the manufacturer's clearances from windows and doors.

Permits in Falmouth

Falmouth does not publish a generator checklist that we could find. A licensed electrician pulls the electrical permit and a licensed gas fitter pulls the gas permit. If the house is in a flood zone, ask the building department early where equipment can sit relative to the flood elevation.

FAQ

Questions about backup power in Falmouth

Falmouth was mostly dark for days in February 2026. Would a battery have lasted?

Falmouth was mostly dark for days in February 2026. Would a battery have lasted?

It depends on what you put on it. A battery sized for heat, water, refrigeration, lights and the network can go a long way, and pairing it with solar or a standby generator lets it recharge during a long outage. We size it from your actual loads.

We live near the water in Woods Hole. Where would the equipment go?

We live near the water in Woods Hole. Where would the equipment go?

Above the flood elevation and out of the way of waves, usually a garage, a raised utility room or an upper level. We look at the lot, and your electrician and the building department confirm the placement.

Can a generator and a Savant system work together in Falmouth?

Can a generator and a Savant system work together in Falmouth?

Yes. Savant Power Storage supports a hardwired standby generator with two-wire start, so the generator can recharge the batteries and carry the house during a long outage. Portable generators are not supported.
