NIPSCO commercial electricity prices, 2015 to 2025

In 2015 NIPSCO billed its commercial customers an average of 11.54¢ per kWh. In 2025 the figure was 19.24¢, so it rose 67% 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 14%.

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 NIPSCO

In 2025 the average commercial price at NIPSCO was 13% below the residential figure and 2.8 times 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 NIPSCO’s commercial rates are set

NIPSCO 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 NIPSCO

EIA counts 60,535 commercial meters at NIPSCO in 2025 and reports no advanced (AMI) meters among them. Of those, 59,757 are automated-reading (AMR) meters, which send a reading to the utility for billing only, and 778 are standard meters. Without an advanced meter a business generally has no interval data, so its peak demand is read from the meter’s own register.

EIA records 198 commercial net-metered generating systems at NIPSCO in 2025, with 45.8 MW of capacity between them: about 3.3 for every 1,000 commercial customers. Net metering credits a customer for power its own system sends to the grid; the terms are in the utility’s tariff.

How reliable is NIPSCO’s electric service?

NIPSCO customers went without power for an average of 178 minutes in 2025, excluding major storms, with about 0.90 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 532 minutes. These are averages over every customer of every class, so they describe the system and not any one street.

Where NIPSCO serves

EIA records NIPSCO serving customers in 20 Indiana counties: Benton, Carroll, DeKalb, Elkhart, Fulton, Jasper, Kosciusko, LaPorte, Lagrange, Lake, Marshall, Newton, Noble, Porter, Pulaski, St Joseph, Starke, Steuben, and 2 more. 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¢)
• Indiana Michigan Power (13.03¢)
• AES Indiana (15.57¢)
• CenterPoint Energy Indiana South (16.70¢)

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 NIPSCO’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.

That is 40% above the Indiana commercial average of 13.70¢. It is the utility’s commercial revenue divided by its commercial sales, so it describes the whole class and is not the rate on any one schedule.

How much is the average commercial electric bill at NIPSCO?

About $1,006 a month in 2025, on average use of about 5,229 kWh a month. That is NIPSCO’s commercial revenue divided by its 60,535 commercial customers. A few very large accounts pull the average up, so most businesses pay less than this.

Is this the rate my business will pay NIPSCO?

No. It is an average over every commercial customer, from a corner shop to a campus. What one business pays depends on its rate schedule, how much it uses and how hard it draws at its peak. The schedule code is printed on the bill, and the schedule itself is in NIPSCO’s tariff.
