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 Indiana Michigan Power
In 2025 the average commercial price at Indiana Michigan Power was 28% below the residential figure and 8.2% 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.
| Customer class | Customers | Sales (MWh) | Average price per kWh | Average use a month | Average bill a month |

How Indiana Michigan Power’s commercial rates are set
Indiana Michigan Power is investor-owned, so its rates are set in cases before the Michigan Public Service 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. What a business in Michigan can and cannot choose is on the Michigan page.
Meters, time-varying rates and net metering at Indiana Michigan Power
EIA counts 19,004 commercial meters at Indiana Michigan Power in 2025, and 18,945 of them (more than 99%) are advanced meters (AMI), which record use at least hourly and report it to the utility at least daily. Of the rest, 2 are automated-reading (AMR) meters, which send a reading to the utility for billing only, and 57 are standard meters. An advanced meter is what makes interval data possible, and interval data is what shows when a building’s peak demand happens.
At Indiana Michigan Power, 396 commercial customers were on a time-varying rate in 2025, about 2.1% of its commercial customers. A time-varying rate charges more in some hours than in others, so when a business uses power matters as well as how much. The kinds Indiana Michigan Power reports offering commercial customers are time-of-use pricing.
EIA records 60 commercial net-metered generating systems at Indiana Michigan Power in 2025, with 1.61 MW of capacity between them: about 3.2 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 Indiana Michigan Power’s electric service?
Indiana Michigan Power customers went without power for an average of 142 minutes in 2025, excluding major storms, with about 1.11 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 932 minutes. These are averages over every customer of every class, so they describe the system and not any one street.
Where Indiana Michigan Power serves
EIA records Indiana Michigan Power serving customers in 6 Michigan counties: Allegan, Berrien, Cass, Kalamazoo, St Joseph, Van Buren. 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 PJM as its balancing authority. PJM is one of the organised wholesale markets, which run the grid and the wholesale power market across their area.
Other utilities in Michigan

- Lansing Board of Water & Light (16.43¢)
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 Indiana Michigan Power’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 Michigan 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.
