In short: Fort Smith has about 90,500 people and sits in Sebastian County. Southwestern Electric Power Co, Oklahoma Gas & Electric Co and Arkansas Valley Elec Coop Corp serves different parts of Sebastian County, so your utility depends on your address; their 2024 home averages range from 11.49¢ to 13.33¢ per kWh (EIA). FEMA rates Sebastian County ice storms “very high”. Rooftop solar here makes roughly 1,300 kWh a year per kW of panels by our estimate, which is good for solar.
This page covers what is local to Fort Smith: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Arkansas energy guide.

Your utility and what it means
Southwestern Electric Power Co is an investor-owned utility and served about 108,102 home customers in 2024; its 11.53¢ average was below the 14.33¢ statewide average for July 2026. Oklahoma Gas & Electric Co is an investor-owned utility and served about 58,218 home customers in 2024; its 11.49¢ average was below the 14.33¢ statewide average for July 2026. Arkansas Valley Elec Coop Corp is a member-owned cooperative utility and served about 54,372 home customers in 2024; its 13.33¢ average was below the 14.33¢ 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, Southwestern Electric Power Co reported 248 minutes per customer without major storms in 2024, more than the statewide figure of 195 (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 Arkansas guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Fort Smith
- Ice storms (very high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
- Tornadoes (relatively high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
- 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 Fort Smith
By our rough estimate each kW of panels makes about 1,300 kWh a year in Fort Smith (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Southwestern Electric Power Co’s 2024 average of 11.53¢, that is about $150 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: June is the sunniest month at 6.56 and December the dimmest at 2.24, a 2.9-to-1 gap.
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. Hail and storm exposure are worth raising with installers and your insurer.
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. Fort Smith has 18 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 Fort Smith building or permitting department, or from Sebastian County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Fort Smith, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Arkansas guide lists the state licensing rules.

Fort Smith energy FAQ
Who is my electric company in Fort Smith?
Southwestern Electric Power Co, Oklahoma Gas & Electric Co and Arkansas Valley Elec Coop Corp all serve parts of Sebastian County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Southwestern Electric Power Co 11.53¢, Oklahoma Gas & Electric Co 11.49¢, Arkansas Valley Elec Coop Corp 13.33¢) so it matters for solar math.
How much power will solar make in Fort Smith?
About 1,300 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 7,800 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 ice storms in Sebastian 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.
Do I need a permit for solar or a generator in Fort Smith?
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.
