Your utility and what it means

Ameren Illinois Company is an investor-owned utility and served about 520,498 home customers in 2024; its 15.26¢ average was below the 19.22¢ statewide average for July 2026. Corn Belt Energy Corporation is a member-owned cooperative utility and served about 34,710 home customers in 2024; its 15.76¢ average was below the 19.22¢ statewide average for July 2026. Eastern Illinois Elec Coop is a member-owned cooperative utility and served about 11,115 home customers in 2024; its 17.1¢ average was below the 19.22¢ 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, Eastern Illinois Elec Coop reported 194 minutes per customer without major storms in 2024, more than the statewide figure of 59 (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 Illinois guide and then ask your utility for its current interconnection steps before you sign anything.

Backup power in Normal

  • 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.
  • Drought (relatively high): Drought raises fire and heat risk and strains wells. If you rely on a well pump, include it in your backup plan.
  • 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 Normal

By our rough estimate each kW of panels makes about 1,170 kWh a year in Normal (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Ameren Illinois Company’s 2024 average of 15.26¢, that is about $179 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 6.31 and December the dimmest at 1.56, 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. Normal has 102 public charging ports in the federal station list including 45 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 Normal building or permitting department, or from McLean County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Normal, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Illinois guide lists the state licensing rules.

Normal energy FAQ

Who is my electric company in Normal?

Ameren Illinois Company, Corn Belt Energy Corporation and Eastern Illinois Elec Coop all serve parts of McLean County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Ameren Illinois Company 15.26¢, Corn Belt Energy Corporation 15.76¢, Eastern Illinois Elec Coop 17.1¢) so it matters for solar math.

How much power will solar make in Normal?

About 1,170 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 7,020 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 McLean 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 Normal?

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.
