Idaho Power Co

What This Utility Data Tells You

Idaho Power Co is an investor-owned utility operating in Idaho under EIA identifier 9191. It reports service to approximately 604,230 customer accounts and generated about $1.42 billion in annual electric revenue, with a service footprint spanning 193 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.

In 2023, the average Idaho Power Co customer experienced 130.4 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. Over the same period, SAIFI (outage events per customer) was 1.07, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 119.7 minutes, and the spread against the headline 130.4 indicates how much weather, versus routine infrastructure, drove the outage total.

Idaho Power Co has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI dropped from 209.8 to 130.4 minutes across that span, a direction regulators and prospective customers tend to watch closely.
