What long-outage Duck River Elec Member Corp filings show
Duck River Elec Member Corp is a member-owned electric cooperative operating in Tennessee under EIA identifier 5399. It reports service to approximately 83,723 customer accounts and generated about $0.22 billion in annual electric revenue, with a service footprint spanning 61 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 Duck River Elec Member Corp customer experienced 307.1 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 2.25 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 175.2 minutes, the gap between that figure and the headline 307.1 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Duck River Elec Member Corp's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 368.1 to 307.1 minutes across that span, a direction regulators and prospective customers tend to watch closely.
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 Duck River Elec Member Corp sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Duck River Elec Member Corp charges more per customer than 56% of them, and is more reliable (lower SAIDI) than 33% 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.
Revenue per customer: $2,627/year · Latest SAIDI: 307.1 minutes/year.
