What short-outage Lehi City Corporation filings show
Lehi City Corporation is a municipally-owned utility operating in Utah under EIA identifier 10879. It reports service to approximately 28,924 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 5 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average Lehi City Corporation customer experienced 41.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 0.38 for the same period, meaning customers statistically saw about 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 41.1 minutes; the difference from the headline 41.1 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Lehi City Corporation's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 138.9 to 41.1 minutes over that window, a meaningful direction for prospective customers and regulators watching 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. Not a measure of electricity rates or customer service, which this portal does not track.
