What long-outage City of Harriman - (TN) filings show
City of Harriman - (TN) is a municipally-owned utility operating in Tennessee under EIA identifier 8147. It reports service to approximately 11,218 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 1 ZIP code. 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 City of Harriman - (TN) customer experienced 919.2 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That exceeds the 120–180 minute national benchmark by a wide margin, a pattern often tied to severe weather exposure, older infrastructure, or longer repair windows. SAIFI, the average number of outage events per customer, was 5.46 for the same period, so customers statistically faced roughly 5 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 919.2 minutes, and the spread against the headline 919.2 indicates how much weather, versus routine infrastructure, drove the outage total.
City of Harriman - (TN) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 748.1 to 919.2 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
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.
