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 Imperial Irrigation District
In 2025 the average commercial price at Imperial Irrigation District was 2.4% below the residential figure and 1.9% below 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 Imperial Irrigation District’s commercial rates are set
Imperial Irrigation District is a public body with its own board, and that board sets its rates. 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 California can and cannot choose is on the California page.
Meters, time-varying rates and net metering at Imperial Irrigation District
EIA counts 22,416 commercial meters at Imperial Irrigation District in 2025, and 22,396 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, 20 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.
EIA records 542 commercial net-metered generating systems at Imperial Irrigation District in 2025, with 76.3 MW of capacity between them: about 25 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 Imperial Irrigation District’s electric service?
Imperial Irrigation District customers went without power for an average of 56 minutes in 2025, excluding major storms, with about 0.66 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes. With major storms counted the figure was 114 minutes. These are averages over every customer of every class, so they describe the system and not any one street.
Where Imperial Irrigation District serves
EIA records Imperial Irrigation District serving customers in 3 California counties: Imperial, Riverside, San Diego. 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 Imperial Irrigation District 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 Imperial Irrigation District’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 California 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.
