Get a Savant Quote

Wellfleet sits on the long, single power line that runs down the Outer Cape along Route 6. When that line is down there is no other way for power to reach town, and in a bad storm it can stay down for days.

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 Wellfleet

In the February 2026 blizzard MEMA listed all 4,461 Wellfleet customers as out at 12:30 p.m. on February 23. MassLive reported that at 6 a.m. on Wednesday, February 25, two days later, Wellfleet was still at 100 percent out.

It is not every storm. On March 12, 2018, only 9 percent of Wellfleet was out at 9 p.m. while Harwich was at 98 percent, which shows how much depends on where the line breaks. In the October 27, 2021 nor'easter, a sole-source circuit failure on the Outer Cape blacked out all of Truro and Provincetown.

Who supplies the power

Eversource serves Wellfleet. Eversource describes the Outer Cape, Wellfleet, Truro and Provincetown, as served by a single distribution line, and it built a utility battery in Provincetown to back that line up. The battery sits at the far end, past Wellfleet. It supports Provincetown's grid. It does not keep Wellfleet houses on.

Which system fits a Wellfleet home?

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

Savant Power

Savant Power lets a Wellfleet house ride out an outage on the circuits that matter, such as heat, the well pump, refrigeration and the network, and the Savant app shows you what is running from wherever you are.

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

For the longest Outer Cape outages, a standby generator on propane is the backstop. It can carry the house by itself or recharge a battery system so the battery never runs flat.

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 Wellfleet

Since 2021, overwash at Duck Harbor has repeatedly flooded Old County Road and Bound Brook Island Road and cut off access to Bound Brook Island. A system for a house like that has to run with no one home and no way for a crew to reach it quickly.

Indoors, a battery cabinet goes in a garage or a dry utility room. A generator pad goes where it clears windows and doors, and for propane, where the delivery truck can reach the tank.

FAQ

Questions about backup power in Wellfleet

Doesn't the Provincetown battery protect Wellfleet?

Doesn't the Provincetown battery protect Wellfleet?

No. It sits at the end of the Outer Cape line in Provincetown and supports that part of the grid. In February 2026 Wellfleet was still entirely without power two days after the storm.

Our Wellfleet house is down a long sand road. Can you still install there?

Our Wellfleet house is down a long sand road. Can you still install there?

Yes. We plan delivery access on the site visit. A battery cabinet comes in through the garage, and for a generator we confirm that the pad location and any propane tank can be reached by the delivery truck.

Can the backup system run a well pump?

Can the backup system run a well pump?

Yes, if the well pump circuit is on the backup plan and the system is sized for its starting load. We take that from the pump's nameplate on the site visit.
