What long-outage Upper Cumberland E M C filings show
Upper Cumberland E M C is a member-owned electric cooperative operating in Tennessee under EIA identifier 19574. It reports service to approximately 53,364 customer accounts and generated about $0.12 billion in annual electric revenue, with a service footprint spanning 43 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.
In 2023, the average Upper Cumberland E M C customer experienced 344.0 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. Excluding major event days (hurricanes, ice storms), SAIDI drops to 255.3 minutes, the gap between that figure and the headline 344.0 reveals how much weather, not day-to-day infrastructure, drove outages.
Upper Cumberland E M C 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 improved from 571.1 to 344.0 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.
