Otter Tail Power commercial electricity prices, 2015 to 2025

In 2015 Otter Tail Power billed its commercial customers an average of 8.00¢ per kWh. In 2025 the figure was 9.38¢, so it rose 17% over 10 years. The average for all commercial customers in Minnesota rose 31% over the same period. The highest year was 2022, at 9.84¢. Between 2024 and 2025 it rose 0.8%.

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 Otter Tail Power

In 2025 the average commercial price at Otter Tail Power was 17% below the residential figure and 61% 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 Otter Tail Power’s commercial rates are set

Otter Tail Power is investor-owned, so its rates are set in cases before the Minnesota Public Utilities 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 Minnesota, so the levers are the schedule, the peak and the amount used.

Meters, time-varying rates and net metering at Otter Tail Power

EIA counts 14,868 commercial meters at Otter Tail Power in 2025, and 14,501 of them (98%) are advanced meters (AMI), which record use at least hourly and report it to the utility at least daily. Of the rest, 263 are automated-reading (AMR) meters, which send a reading to the utility for billing only, and 104 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 Otter Tail Power, 1,836 commercial customers were on a time-varying rate in 2025, about 14% 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 Otter Tail Power reports offering commercial customers are time-of-use pricing and critical peak pricing.

EIA records 54 commercial net-metered generating systems at Otter Tail Power in 2025, with 2.43 MW of capacity between them: about 4.1 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 Otter Tail Power’s electric service?

Otter Tail Power customers went without power for an average of 136 minutes in 2025, excluding major storms, with about 1.32 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 557 minutes. These are averages over every customer of every class, so they describe the system and not any one street.

Where Otter Tail Power serves

EIA records Otter Tail Power serving customers in 30 Minnesota counties: Becker, Beltrami, Big Stone, Cass, Chippewa, Clay, Clearwater, Douglas, Grant, Kandiyohi, Kittson, Lac Qui Parle, Lincoln, Lyon, Mahnomen, Marshall, Norman, Otter Tail, and 12 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 Minnesota

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

• Xcel Energy Minnesota (12.73¢)
• Minnesota Power (14.75¢)
• Connexus Energy (10.99¢)

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 Otter Tail 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 Minnesota 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.
