In short: Erlanger has about 20,200 people and sits in Kenton County. Duke Energy Kentucky and Owen Electric Coop Inc serves different parts of Kenton County, so your utility depends on your address; their 2024 home averages range from 12.55¢ to 13.44¢ per kWh (EIA). FEMA rates Kenton County strong winds “relatively high”. Rooftop solar here makes roughly 1,160 kWh a year per kW of panels by our estimate, which is about average for the U.S..
This page covers what is local to Erlanger: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Kentucky energy guide.

Your utility and what it means
Duke Energy Kentucky is an investor-owned utility and served about 139,405 home customers in 2024; its 13.44¢ average was close to the 13.81¢ statewide average for July 2026. Owen Electric Coop Inc is a member-owned cooperative utility and served about 63,984 home customers in 2024; its 12.55¢ average was below the 13.81¢ 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, Owen Electric Coop Inc reported 126 minutes per customer without major storms in 2024, less than the statewide figure of 153 (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 Kentucky guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Erlanger
- Strong winds (relatively high): High winds knock out lines on ordinary days. A battery or portable power station handles the common short outages; add a generator for multi-day repairs.
- 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 Erlanger
By our rough estimate each kW of panels makes about 1,160 kWh a year in Erlanger (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Duke Energy Kentucky’s 2024 average of 13.44¢, that is about $156 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 6.20 and December the dimmest at 1.54, 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. 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. Erlanger has 8 public charging ports in the federal station list including 2 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 Erlanger building or permitting department, or from Kenton County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Erlanger, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Kentucky guide lists the state licensing rules.

Erlanger energy FAQ
Who is my electric company in Erlanger?
Duke Energy Kentucky and Owen Electric Coop Inc both serve parts of Kenton County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Duke Energy Kentucky 13.44¢, Owen Electric Coop Inc 12.55¢) so it matters for solar math.
How much power will solar make in Erlanger?
About 1,160 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 6,960 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 strong winds in Kenton 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 Erlanger?
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.
