What short-outage City of Idaho Falls - (ID) filings show

In 2023, the average City of Idaho Falls - (ID) customer experienced 39.9 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index).

Over the same period, SAIFI (outage events per customer) was 0.45, putting the typical customer at roughly 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 22.1 minutes, the gap between that figure and the headline 39.9 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), City of Idaho Falls - (ID)'s reliability record can be judged on trend rather than one isolated year. Over that window, SAIDI moved from 183.6 down to 39.9 minutes, a trend worth noting for anyone weighing capital investment outcomes.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide.
