What long-outage Sevier County Electric System filings show
Sevier County Electric System is a municipally-owned utility operating in Tennessee under EIA identifier 16949. It reports service to approximately 61,951 customer accounts and generated about $0.17 billion in annual electric revenue, with a service footprint spanning 15 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average Sevier County Electric System customer experienced 462.0 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI, the average number of outage events per customer, was 3.02 for the same period, so customers statistically faced roughly 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 215.0 minutes, and the spread against the headline 462.0 indicates how much weather, versus routine infrastructure, drove the outage total.
Sevier County Electric System has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that window, SAIDI moved from 1566.5 down to 462.0 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. Not a measure of electricity rates or customer service, which this portal does not track.

Price vs. reliability
Where Sevier County Electric System sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Sevier County Electric System charges more per customer than 66% of them, and is more reliable (lower SAIDI) than 21% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
