Backup Power
Whole-Home Generator Installation in Boston
Massachusetts has a strong grid on an average day. U.S. Energy Information Administration data for 2024 puts the national average at 11 hours of power interruption per customer, while Massachusetts customers averaged under two hours and fewer than one interruption for the year. [1] The problem here is not routine flicker. It is the concentrated multi-day outage that follows a nor’easter, when the temperature is in the twenties, and the heating system needs electricity to run.
A standby generator is a permanently installed unit wired into your electrical panel and fed by natural gas or propane. When it senses a utility outage, an automatic transfer switch disconnects the house from the grid and starts the generator, usually within seconds, which keeps the heat on and the refrigerator cold without anyone going outside. Our electrical team sizes the unit to your actual load, handles the load calculation, and pulls the permits your city or town requires.

Planning The Right Way
What Affects Home Generator Installation Pricing?
The cost of a whole-home generator installation depends on the size of the generator, the amount of your home you want to power, your fuel source, and the work required to connect the system safely. Your home’s electrical setup, generator placement, automatic transfer switch, permits, and any necessary electrical or gas line work can also affect the total price.
Sila starts with an in-home assessment to understand your backup power needs and review your existing electrical system. We can recommend the appropriate generator size, explain the work involved, and provide the project cost in writing before installation begins.

Automatic Protection
Keep Your Home Running During Outages
The practical difference between a standby unit and a portable generator shows up at two in the morning. A standby system starts on its own, powers circuits through the panel, and needs nothing from you. A portable requires someone to go out in the weather, start an engine, and run extension cords to whatever gets priority.
Eastern Massachusetts has recent evidence of how long an outage can last. Three nor’easters hit inside two weeks in March 2018: the first, on March 1 through 3, cut power to more than 400,000 Massachusetts customers, and more than 71,000 were still without it two days later. 3 A second storm on March 7 and 8 left roughly 300,000 customers without power across central and northeastern Massachusetts. 4 The January 28 to 29, 2022 blizzard dropped 23.6 inches on Boston in one day, tying the single-day record, and cut power to more than 115,000 customers statewide, concentrated on the South Shore and Cape Cod. 5,6
Permanent generators run off your natural gas or propane line, so there is no gasoline to store or stabilize. In exchange, you take on annual service and the fuel cost during extended runs. Permanent generators also require ongoing maintenance and use natural gas or propane during extended outages. We can explain those considerations as you compare generator options for your home.
Permits and Documentation
A Permitted Installation You Can Hand to the Next Owner
A standby generator is a piece of permanently installed equipment tied into two utilities, which is why the paperwork carries weight. We pull the electrical and gas permits, schedule the municipal inspection, and leave you with the permit records, the load calculation, the model and serial numbers, and the commissioning results.
That file matters later. It tells a service technician what is installed and how it was wired; it answers the questions an insurer or a home inspector asks; and it saves the next owner from guessing at an unlabeled transfer switch. Undocumented and unpermitted work is one of the more common problems we find when we take over service on someone else’s installation.
We install to the manufacturer’s instructions and to the codes your municipality enforces, and we label the transfer switch and the generator circuits so the system is legible to whoever opens the panel next.

Common Questions
Frequently Asked Questions About Generators
The physical installation generally runs one to two days. Permitting and municipal inspection scheduling usually add several weeks, and that timeline varies by town.
Do Standby Generators Require Maintenance?
Yes. Budget for annual service, which typically covers an oil change, a battery check, filter replacement, and a transfer switch test. Missed service is a common reason a generator fails to start when it is needed.
Can a Generator Power My Central A/C System?
A correctly sized unit can run central A/C along with your other major appliances, though air conditioning has a high starting draw and drives the sizing significantly. We run the load calculation during the site visit so the capacity matches what you actually intend to power.
How Long Does a Whole-Home Generator Installation Take?
The physical installation generally runs one to two days. Permitting and municipal inspection scheduling usually add several weeks, and that timeline varies by town.
What Type of Fuel Does a Whole-Home Generator Use?
Permanent units connect to natural gas or liquid propane, which gives you a continuous supply during a long outage. You pay for the fuel consumed while the unit runs.
Will the Generator Start Automatically When the Power Goes Out?
Yes. The automatic transfer switch detects the utility failure, isolates your house from the grid, and starts the generator, typically within seconds, then returns the house to utility power once the grid is stable.
Speak With Our Electrical Team
Sizing a generator involves more variables than most homeowners expect, from well pumps to heat pump lockouts to the outdoor temperature at which a control disables the compressor. Our team can talk through the options and tell you what we would put in a house like yours.
