What long-outage SEMO Electric Cooperative filings show
SEMO Electric Cooperative is a member-owned electric cooperative operating in Missouri under EIA identifier 16805. It reports service to approximately 16,248 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 35 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 SEMO Electric Cooperative customer experienced 687.5 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. Over the same period, SAIFI (outage events per customer) was 2.53, putting the typical customer at roughly 3 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 687.5 minutes, the gap between that figure and the headline 687.5 reveals how much weather, not day-to-day infrastructure, drove outages.
SEMO Electric Cooperative has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI climbed from 165.0 to 687.5 minutes over that window, a shift that can point to 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.

Price vs. reliability
Where SEMO Electric Cooperative sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, SEMO Electric Cooperative charges more per customer than 59% of them, and is more reliable (lower SAIDI) than 14% 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: $2,681/year · Latest SAIDI: 687.5 minutes/year.
