Sequachee Valley Electric Coop is a member-owned electric cooperative operating in Tennessee under EIA identifier 16930. It reports service to approximately 38,597 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 30 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.
In 2023, the average Sequachee Valley Electric Coop customer experienced 487.5 minutes of power interruptions, a metric called SAIDI (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. Over the same period, SAIFI (outage events per customer) was 3.42, putting the typical customer at roughly 3 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 226.7 minutes, the gap between that figure and the headline 487.5 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Sequachee Valley Electric Coop's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 363.4 to 487.5 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
