Home Battery Backup in Brockton
Brockton's community electricity plan is waiting on the DPU, and National Grid's Basic Service price rose in August. Neither changes who restores the power when it goes out — or what a battery does when it does.
DPU hearing on Brockton's aggregation plan: November 2, 2026, 2 p.m. Until launch, Basic Service is 17.185¢/kWh.
The short answer
Brockton is National Grid territory. The City's Brockton Community Electricity plan was filed with the DPU on September 16, 2026, with a public hearing on November 2; it is not live yet, so most homes are on National Grid Basic Service at 17.185¢ per kWh through January 2027.
Aggregation would change the supply price, not who restores outages, and the program says solar credits carry over. A battery's job is the same either way: keep the circuits you choose running until National Grid is done. We size it to a critical load panel and handle the interconnection.

Three things that are specific to here
Brockton is between supply arrangements. Here is what is settled and what isn't.
Aggregation is filed, not live
Brockton filed its community electricity plan with the Department of Public Utilities on September 16, 2026 (docket 26-121). The DPU has set a public hearing for November 2, 2026 at 2 p.m. The program can only launch after approval and a supply contract.
Basic Service went up in August
National Grid's fixed residential Basic Service price rose from 15.372¢ per kWh (February–July 2026) to 17.185¢ for August 2026 through January 2027. On the monthly variable option, January 2027 is listed at 20.086¢.
National Grid still runs the wires
Aggregation changes who supplies the electricity, not who delivers it. National Grid remains the utility that restores outages and handles solar and battery interconnection, whatever Brockton's program ends up charging.
What a Brockton battery actually does
A battery doesn't prevent an outage. It decides which circuits keep running until the crew is done.
A supply price doesn't keep the lights on
However the aggregation vote goes, an outage on your street is National Grid's to fix. A battery with a transfer switch keeps the circuits you choose running until it does.
Solar credits carry over
Brockton's program site says customers receiving net metering or community shared solar credits keep those benefits under aggregation. A battery decision doesn't need to wait for the DPU.
Summer program, winter outages
National Grid's ConnectedSolutions pays batteries for summer-afternoon events, while winter storms are the classic outage season. How much of the battery to reserve is a real design choice; the Lowell page walks through it.
The critical-load list
Heating-system controls and circulators, refrigeration, a sump pump, internet and lights are the usual list. A heat-pump-heated house is a much bigger winter battery decision.
Brockton next to its neighbours
To the north, Quincy shows what a running aggregation looks like — a fixed supply price through 2027, with two delivery utilities still doing the restoring. Lowell covers National Grid's ConnectedSolutions season against winter outages, and Boston covers harbour storms and urban panels. On the water side, Brockton water quality has its own page.

What a home battery job with us covers
Installation of storage and the backup circuits behind it, with the siting and utility paperwork handled.
Battery installation
Wall or floor-mounted storage installed to the listing and to the residential code sections that govern where it may go.
Backup and critical load panel
Deciding and wiring which circuits stay live, and which must never be on backup — the choice that defines what an outage feels like.
Integration with existing PV solar
Connecting storage to an array that is already on the roof, including whether the existing inverter supports it.
Transfer switch and disconnection
The equipment that separates the house from the grid during an outage, which is what makes backup legal as well as possible.
Siting to code
Location, clearances, separation and impact protection assessed against the adopted code before anything is mounted.
Permit, inspection and utility approval
The electrical permit, the inspection, and the utility's own approval step where storage touches the service.
This is installation work. No runtime, capacity or incentive figure is quoted before your loads and your utility are confirmed. Coverage is confirmed per service area rather than promised as blanket availability.
What the work actually looks like
A battery job is an electrical job. The panel, the circuits and the disconnection are most of it.
Battery backup in Brockton, answered plainly
Who is the electric utility in Brockton?+
National Grid. It delivers the power, restores outages and handles interconnection for solar and batteries. Brockton's planned community electricity program would change the supply price, not the utility.
Has Brockton's community electricity program started?+
Not yet. The City filed its aggregation plan with the DPU on September 16, 2026, and the DPU scheduled a public hearing for November 2, 2026 at 2 p.m. After DPU approval, the City can buy supply and launch, with an education campaign and an opt-out period first. No program price has been announced.
What is National Grid's Basic Service rate right now?+
National Grid's fixed residential Basic Service price is 17.185¢ per kWh for August 1, 2026 through January 31, 2027, up from 15.372¢ for February through July 2026. That is the supply portion only; delivery charges are separate.
Should I wait for aggregation before adding a battery?+
There's no need to on the program's account. The program site says net metering and community solar credits continue under aggregation, and a battery's outage value doesn't depend on the supply price. We don't sell a battery on supply-price savings.
How long will a battery run my house?+
It depends on the battery's capacity, the circuits on it and the season, so we don't quote a runtime before seeing the panel and your loads.
Who installs it, and who is responsible afterwards?+
Seamless Home is the licensed contractor of record on the work it runs. Installation is performed by vetted installing partners engaged as our subcontractors, so the permit, the inspection and any correction notice carry one name. Coverage is confirmed per service area rather than promised as blanket availability.
