In short: Woonsocket has about 44,500 people and sits in Providence County. The Narragansett Electric Co and Pascoag Utility District serves different parts of Providence County, so your utility depends on your address; their 2024 home averages range from 16.52¢ to 28.26¢ per kWh (EIA). FEMA rates Providence County heat waves “relatively high”. Rooftop solar here makes roughly 1,110 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 Woonsocket: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Rhode Island energy guide and the wider area is covered in the Providence guide.
Woonsocket at a glance
- Place: Woonsocket, Providence County, Rhode Island; about 44,508 residents (Census Bureau estimate, July 2024).
- Utility: The Narragansett Electric Co (investor-owned). Homes paid an average 28.26¢ per kWh in 2024 (EIA-861); the average customer lost 61 minutes of power on normal days and 104 counting major storms, with 0.8 interruptions a year (utility-wide, not just Woonsocket).
- Utility: Pascoag Utility District (city-owned). Homes paid an average 16.52¢ per kWh in 2024 (EIA-861) (utility-wide, not just Woonsocket).
- Sun: 3.81 kWh per square meter per day on average, from 1.49 in December to 5.96 in July (NASA POWER). Our rough estimate: about 1,110 kWh a year per kW of panels.
- Climate: about 730 cooling degree-days and 5,990 heating degree-days a year (base 65°F, NASA POWER), so heating is the big load.
- Top hazards in Providence County: heat waves “relatively high”, river and heavy-rain flooding “relatively high” and cold waves “relatively high” (FEMA National Risk Index; overall county risk rated “relatively moderate”).
- Public charging: 15 ports at 8 locations in Woonsocket, none of them DC fast (AFDC, October 20, 2026).
Your utility and what it means
The Narragansett Electric Co is an investor-owned utility and served about 332,540 home customers in 2024; its 28.26¢ average was close to the 28.29¢ statewide average for July 2026. Pascoag Utility District is a city-owned utility and served about 4,373 home customers in 2024; its 16.52¢ average was below the 28.29¢ 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, The Narragansett Electric Co reported 61 minutes per customer without major storms in 2024, less than the statewide figure of 61 (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 Rhode Island guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Woonsocket
- Heat waves (relatively high): Heat waves strain the grid just when air conditioning matters most. Decide what must stay cool, such as one room, medicine and the fridge, and size backup to that rather than the whole house.
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- 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 Woonsocket
By our rough estimate each kW of panels makes about 1,110 kWh a year in Woonsocket (NASA sunshine data times 365 days times 0.80 for system losses). Valued at The Narragansett Electric Co’s 2024 average of 28.26¢, that is about $314 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 5.96 and December the dimmest at 1.49, a 4.0-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. Woonsocket has 15 public charging ports in the federal station list (none of them 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 Woonsocket building or permitting department, or from Providence County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Woonsocket, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Rhode Island guide lists the state licensing rules.

Woonsocket energy FAQ
Who is my electric company in Woonsocket?
The Narragansett Electric Co and Pascoag Utility District both serve parts of Providence County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (The Narragansett Electric Co 28.26¢, Pascoag Utility District 16.52¢) so it matters for solar math.
How much power will solar make in Woonsocket?
About 1,110 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 6,660 kWh. Shade, roof direction and tilt change this; run your address through the solar potential tool for a better number.
Is a generator or a battery better for heat waves in Providence County?
It depends how long the outage lasts. A battery is quiet, automatic and good for short outages and for pairing with solar; a standby generator keeps going as long as it has fuel, which suits multi-day events. Many homes use a battery for everyday outages and add a generator for the rare long one.
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 Woonsocket?
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.
