Your utility and what it means
Duke Energy Indiana, LLC is an investor-owned utility and served about 796,265 home customers in 2024; its 12.75¢ average was below the 16.73¢ statewide average for July 2026. Utilities Dist-Western IN REMC is a member-owned cooperative utility and served about 18,898 home customers in 2024; its 16.1¢ average was below the 16.73¢ statewide average for July 2026. Western Indiana Energy REMC is a member-owned cooperative utility and served about 15,017 home customers in 2024; its 14.39¢ average was below the 16.73¢ 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, Utilities Dist-Western IN REMC reported 431 minutes per customer without major storms in 2024, more than the statewide figure of 121 (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 Indiana guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Terre Haute
- 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.
- Winter weather (relatively high): Winter storms and cold snaps combine outages with heating demand. Plan for the furnace blower or heat pump, not just lights, and keep a fuel supply you can reach in snow.
- 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 Terre Haute
By our rough estimate each kW of panels makes about 1,180 kWh a year in Terre Haute (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Duke Energy Indiana, LLC’s 2024 average of 12.75¢, 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 6.34 and December the dimmest at 1.58, 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. Terre Haute has 50 public charging ports in the federal station list including 40 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 Terre Haute building or permitting department, or from Vigo County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Terre Haute, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Indiana guide lists the state licensing rules.

Terre Haute energy FAQ
Who is my electric company in Terre Haute?
Duke Energy Indiana, LLC, Utilities Dist-Western IN REMC and Western Indiana Energy REMC all serve parts of Vigo County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Duke Energy Indiana, LLC 12.75¢, Utilities Dist-Western IN REMC 16.1¢, Western Indiana Energy REMC 14.39¢) so it matters for solar math.
How much power will solar make in Terre Haute?
About 1,180 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 7,080 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 Vigo 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 Terre Haute?
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.
