Where Idaho Power Co sits
It is the dominant supplier in Idaho, serving 525,751 residential customers, so its pricing effectively sets what the state average looks like. Its 11.76¢ per kilowatt-hour sits 4.8% below the Idaho average of 12.35¢.
Consumption is close to the national norm at 916 kilowatt-hours a month against 871, so the rate translates fairly directly into the bill.
A shareholder-owned company whose rates are set by the state regulator, including an approved return on the capital it has invested. 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.

How often the power goes out
In 2024 the average Idaho Power Co customer went 206 minutes without electricity across 1.37 interruptions. The median across the 941 utilities that report this is 185 minutes.
That is worse than typical. Overhead lines through wooded or storm-exposed terrain are the usual explanation, and the fix is vegetation management and circuit automation, both of which are recovered through rates.
Optional rate plans
Idaho Power Co offers time-of-use pricing to residential customers. 992 households were enrolled, about 0.2% of its residential base.
These plans are opt-in almost everywhere. They reward households that can move laundry, dishwashing, water heating or electric vehicle charging out of the late-afternoon peak, and they cost more than the standard rate for households that cannot. How to tell which group you are in.
Rooftop solar on this system
18,207 residential customers had net-metered solar in 2024, totalling 140.51 megawatts. That works out to 34.6 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.
