In short: Appleton has about 75,300 people and sits in Outagamie County. Wisconsin Electric Power Co, Wisconsin Public Service Corp and City of Kaukauna serves different parts of Outagamie County, so your utility depends on your address; their 2024 home averages range from 12.53¢ to 19.23¢ per kWh (EIA). FEMA rates Outagamie County cold 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 Appleton: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Wisconsin energy guide and the wider area is covered in the Green Bay guide.

Your utility and what it means
Wisconsin Electric Power Co is an investor-owned utility and served about 1,048,148 home customers in 2024; its 19.23¢ average was close to the 19.06¢ statewide average for July 2026. Wisconsin Public Service Corp is an investor-owned utility and served about 411,775 home customers in 2024; its 16.23¢ average was below the 19.06¢ statewide average for July 2026. City of Kaukauna is a city-owned utility and served about 14,543 home customers in 2024; its 12.53¢ average was below the 19.06¢ 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, Wisconsin Electric Power Co reported 109 minutes per customer without major storms in 2024, more than the statewide figure of 91 (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 Wisconsin guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Appleton
- Cold waves (relatively high): Cold waves raise demand and can cause both outages and frozen pipes. Keep at least one room warm with a battery-run heater circuit or a generator.
- Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- 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 Appleton
By our rough estimate each kW of panels makes about 1,110 kWh a year in Appleton (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Wisconsin Electric Power Co’s 2024 average of 19.23¢, that is about $213 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 6.26 and December the dimmest at 1.23, a 5.1-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. Appleton has 51 public charging ports in the federal station list including 17 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 Appleton building or permitting department, or from Outagamie County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Appleton, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Wisconsin guide lists the state licensing rules.

Appleton energy FAQ
Who is my electric company in Appleton?
Wisconsin Electric Power Co, Wisconsin Public Service Corp and City of Kaukauna all serve parts of Outagamie County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Wisconsin Electric Power Co 19.23¢, Wisconsin Public Service Corp 16.23¢, City of Kaukauna 12.53¢) so it matters for solar math.
How much power will solar make in Appleton?
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 cold waves in Outagamie 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 Appleton?
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.
