KUB commercial electricity prices, 2015 to 2025

In 2015 KUB billed its commercial customers an average of 10.04¢ per kWh. In 2025 the figure was 13.21¢, so it rose 32% over 10 years. The average for all commercial customers in Tennessee rose 27% over the same period. The latest year, 2025, is the highest of the 11 on record here. Between 2024 and 2025 it rose 11%.

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 KUB

In 2025 the average commercial price at KUB was 4.5% below the residential figure and 2.4 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 KUB’s commercial rates are set

KUB is owned by the community it serves. Its rates are set locally, by the city council or a utility board, and in most states the state commission does not set them. 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 Tennessee, so the levers are the schedule, the peak and the amount used.

Meters, time-varying rates and net metering at KUB

EIA counts 25,666 commercial meters at KUB in 2025, and 25,652 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, 14 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 KUB, 366 commercial customers were on a time-varying rate in 2025, about 1.4% 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 KUB reports offering commercial customers are time-of-use pricing.

How reliable is KUB’s electric service?

KUB customers went without power for an average of 149 minutes in 2025, excluding major storms, with about 0.99 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 274 minutes. These are averages over every customer of every class, so they describe the system and not any one street.

Where KUB serves

EIA records KUB serving customers in 7 Tennessee counties: Anderson, Blount, Grainger, Jefferson, Knox, Sevier, Union. 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 the Tennessee Valley Authority as its balancing authority, the body that keeps supply and demand matched minute by minute across the area.

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 KUB’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 Tennessee 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.
