What mid-pack Southeastern IL Elec Coop, Inc filings show
Southeastern IL Elec Coop, Inc is a member-owned electric cooperative operating in Illinois under EIA identifier 17585. It reports service to approximately 24,796 customer accounts and generated about $0.09 billion in annual electric revenue, with a service footprint spanning 50 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 Southeastern IL Elec Coop, Inc customer experienced 204.9 minutes of power interruptions, a metric called SAIDI (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. Over the same period, SAIFI (outage events per customer) was 1.80, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 135.6 minutes, the gap between that figure and the headline 204.9 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Southeastern IL Elec Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 170.3 to 204.9 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.
