Imperial Irrigation District electricity rates

It serves 142,078 residential customers in California. At 17.91¢ per kilowatt-hour it is one of the cheaper places to buy electricity in California, 46.1% under the statewide average of 33.25¢.

Its customers use more electricity than the national norm, 1,159 kilowatt-hours a month against 871, which amplifies whatever the rate does.

A public body created by the state or county, governed by an elected or appointed board rather than by shareholders. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

In 2024 the average Imperial Irrigation District customer went 61 minutes without electricity across 0.69 interruptions. The median across the 941 utilities that report this is 185 minutes.

That is markedly better than typical. Short outage durations usually mean an underground or heavily automated network, and they are expensive to achieve, which is part of why reliable systems often carry higher delivery charges.

10,215 residential customers had net-metered solar in 2024, totalling 78.33 megawatts. That works out to 71.9 installations per thousand customers, against a median of 8 across the utilities reporting it.

Adoption here is exceptionally high. That usually means some combination of a high retail rate worth displacing, strong sunshine and favourable export rules, and it tends to bring its own regulatory argument about who covers the fixed cost of the network. What exports are actually worth.
