CenterPoint Energy Indiana South commercial electricity prices, 2015 to 2025

In 2015 CenterPoint Energy Indiana South billed its commercial customers an average of 11.97¢ per kWh. In 2025 the figure was 16.70¢, so it rose 40% over 10 years. The average for all commercial customers in Indiana rose 40% over the same period. The latest year, 2025, is the highest of the 11 on record here. Between 2024 and 2025 it rose 6.5%.

Average use and average bill are the utility’s commercial sales and revenue divided by its commercial customers and by twelve. The bill is an all-in figure: energy, delivery, demand and fixed charges together. A few very large customers pull both averages up, so most businesses use and pay less than the average.

Residential, commercial and industrial prices at CenterPoint Energy Indiana South

In 2025 the average commercial price at CenterPoint Energy Indiana South was 16% below the residential figure and 73% above the industrial one. Larger customers take power at a higher voltage and use it more steadily, so at most utilities the average falls from residential to commercial to industrial. Which class an account falls in is the utility’s decision, and the line between commercial and industrial is drawn differently from one utility to the next.

How CenterPoint Energy Indiana South’s commercial rates are set

CenterPoint Energy Indiana South is investor-owned, so its rates are set in cases before the Indiana Utility Regulatory Commission and published in a tariff, which is a public document. A commercial account is billed on a rate schedule, chosen by the size of the account and the voltage it takes power at, and a schedule usually combines a fixed monthly charge, a charge per kWh and, above a certain size, a demand charge on the highest rate of draw in the month. The schedule code is printed on the bill. There is no competitive supply market for ordinary commercial accounts in Indiana, so the levers are the schedule, the peak and the amount used.

Meters, time-varying rates and net metering at CenterPoint Energy Indiana South

EIA counts 24,260 commercial meters at CenterPoint Energy Indiana South in 2025, and 24,260 of them (100%) are advanced meters (AMI), which record use at least hourly and report it to the utility at least daily. An advanced meter is what makes interval data possible, and interval data is what shows when a building’s peak demand happens.

EIA records 126 commercial net-metered generating systems at CenterPoint Energy Indiana South in 2025, with 11.1 MW of capacity between them: about 6.4 for every 1,000 commercial customers.

How reliable is CenterPoint Energy Indiana South’s electric service?

Where CenterPoint Energy Indiana South serves

EIA records CenterPoint Energy Indiana South serving customers in 7 Indiana counties: Dubois, Gibson, Pike, Posey, Spencer, Vanderburgh, Warrick. A county can be shared between utilities, so this does not tell you who serves a given address. The utility that serves an address is the one named on its bill.

EIA lists MISO as its balancing authority. MISO is one of the organised wholesale markets, which run the grid and the wholesale power market across their area.

Other utilities in Indiana

The average each billed its commercial customers in 2025. The Indiana page has the state’s own figures and every utility with 500 or more commercial customers.

• Duke Energy Indiana (11.75¢)
• NIPSCO (19.24¢)
• Indiana Michigan Power (13.03¢)
• AES Indiana (15.57¢)

What these figures can and cannot tell you

• They are averages over every commercial customer. A utility whose commercial customers are mostly large averages fewer cents per kWh than one serving mostly small shops, so a lower figure can mean larger customers and not a lower rate.
• They are not a rate schedule. None of these figures is a charge printed in CenterPoint Energy Indiana South’s tariff, and nothing here works out a bill from one. The tariff index lists the utilities whose filed schedules are quoted on this site.
• They are annual and final. EIA publishes utility figures once a year. The Indiana page carries the state’s trailing 12 months, which is more recent and still preliminary.

For one building, the cost estimator gives a range by building type, size and state, and price by utility sets every utility side by side. Commercial vs residential vs industrial compares the classes in every state.
