In short: New Britain has about 75,900 people and sits in Hartford County. Connecticut Light & Power Co serves the county, averaging 28.51¢ per kWh for homes in 2024 (EIA). Rooftop solar here makes roughly 1,140 kWh a year per kW of panels by our estimate, which is on the modest side, so price and incentives matter more.
This page covers what is local to New Britain: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Connecticut energy guide and the wider area is covered in the Hartford guide.
New Britain at a glance
- Place: New Britain, Hartford County, Connecticut; about 75,871 residents (Census Bureau estimate, July 2024).
- Utility: Connecticut Light & Power Co (investor-owned). Homes paid an average 28.51¢ per kWh in 2024 (EIA-861); the average customer lost 77 minutes of power on normal days and 159 counting major storms, with 0.6 interruptions a year (utility-wide, not just New Britain).
- Sun: 3.91 kWh per square meter per day on average, from 1.54 in December to 6.02 in July (NASA POWER). Our rough estimate: about 1,140 kWh a year per kW of panels.
- Climate: about 780 cooling degree-days and 5,840 heating degree-days a year (base 65°F, NASA POWER), so heating is the big load.
- Public charging: 140 ports at 39 locations in New Britain, 4 of them DC fast (AFDC, October 20, 2026).
Your utility and what it means
Connecticut Light & Power Co is an investor-owned utility and served about 924,132 home customers in 2024; its 28.51¢ average was above the 24.16¢ statewide average for July 2026. Those are utility-wide averages, not a quote for your address; your own bill is the real number.
For reliability, Connecticut Light & Power Co reported 77 minutes per customer without major storms in 2024, more than the statewide figure of 73 (EIA-861). Utility-wide numbers hide a lot: a home at the end of a long rural line usually has more outages than the average.
Net metering, export rates and incentives are set at state level and by each utility. Start with the Connecticut guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in New Britain
- Heating load: a winter outage can stop a furnace blower, boiler pump or heat pump. List what your heat needs to run before choosing a generator or battery.
- Short outages: a portable power station covers phones, Wi-Fi, a CPAP and lights; a home battery switches over automatically.
Size your setup with the generator sizing tool and the battery backup calculator, and compare options in backup power. Generator safety (CPSC): outdoors only, at least 20 feet from the house, exhaust away from doors and windows, never in a garage, and battery-powered carbon monoxide alarms inside. A licensed electrician should install any transfer switch, with a permit; see generator installation.
Solar in New Britain
By our rough estimate each kW of panels makes about 1,140 kWh a year in New Britain (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Connecticut Light & Power Co’s 2024 average of 28.51¢, that is about $325 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: July is the sunniest month at 6.02 and December the dimmest at 1.54, a 3.9-to-1 gap, so a battery or a bigger system helps in winter.
Check your own roof with the solar potential tool, see solar costs and net metering vs net billing, and read the steps in solar installation.
Batteries and EV charging
A home battery earns its place when outages are frequent, when your utility pays little for exported solar, or when evening prices are high; compare in home batteries and battery costs. New Britain has 140 public charging ports in the federal station list including 4 DC fast, but home charging is cheaper and easier: see the EV charging cost calculator and EV charger installation.

Permits and inspections
Solar, generator transfer switches and EV chargers normally need an electrical permit from the New Britain building or permitting department, or from Hartford County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for New Britain, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Connecticut guide lists the state licensing rules.

New Britain energy FAQ
Who is my electric company in New Britain?
Federal data lists Connecticut Light & Power Co as the main utility serving Hartford County. Small areas can be served by a different company or a co-op, so confirm on your bill.
How much power will solar make in New Britain?
About 1,140 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 6,840 kWh. Shade, roof direction and tilt change this; run your address through the solar potential tool for a better number.
Will a home battery keep my heat on in an outage?
It can keep a furnace blower, boiler pump or a heat pump running for a while, but long cold outages drain a battery fast without solar to recharge it. Pair it with a generator or wood or propane heat if outages here run for days.
Do I need a permit for solar or a generator in New Britain?
Almost always an electrical permit for a transfer switch, solar or an EV charger, issued by the city or county where you live. Your licensed electrician or installer normally pulls it. Never connect a generator to your house wiring without a transfer switch.
