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 Rocky Mountain Power
In 2025 the average commercial price at Rocky Mountain Power was 14% below the residential figure and 22% 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 |
|---|---|---|---|---|---|
| Residential | 75,599 | 806,900 | 13.53¢ | 889 kWh | $120 |
| Commercial | 11,077 | 598,477 | 11.61¢ | 4,502 kWh | $523 |

How Rocky Mountain Power’s commercial rates are set
Rocky Mountain Power is investor-owned, so its rates are set in cases before the Idaho 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 Idaho, so the levers are the schedule, the peak and the amount used.
Meters, time-varying rates and net metering at Rocky Mountain Power
EIA counts 12,844 commercial meters at Rocky Mountain Power in 2025, and 12,772 of them (99%) are advanced meters (AMI), which record use at least hourly and report it to the utility at least daily. Of the rest, 1 are automated-reading (AMR) meters, which send a reading to the utility for billing only, and 71 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 Rocky Mountain Power, 16 commercial customers were on a time-varying rate in 2025, about 0.1% 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 Rocky Mountain Power reports offering commercial customers are time-of-use pricing.
EIA records 87 commercial net-metered generating systems at Rocky Mountain Power in 2025, with 1.65 MW of capacity between them: about 7.9 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 Rocky Mountain Power’s electric service?
Rocky Mountain Power customers went without power for an average of 146 minutes in 2025, excluding major storms, with about 1.16 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. These are averages over every customer of every class, so they describe the system and not any one street.
Where Rocky Mountain Power serves
EIA records Rocky Mountain Power serving customers in 14 Idaho counties: Bannock, Bear Lake, Bingham, Bonneville, Butte, Caribou, Clark, Franklin, Fremont, Jefferson, Madison, Oneida, Power, Teton. 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 PacifiCorp East as its balancing authority, the body that keeps supply and demand matched minute by minute across the area.
Other utilities in Idaho
The average each billed its commercial customers in 2025. The Idaho page has the state’s own figures and every utility with 500 or more commercial customers.
- Idaho Power (9.09¢)
- Avista (9.60¢)
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 Rocky Mountain 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 Idaho 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.

A utility average cannot tell you whether your bill is right. The bill itself can, and it takes three numbers. Nobody calls unless you ask.
