What long-outage Corn Belt Energy Corporation filings show
Corn Belt Energy Corporation is a member-owned electric cooperative operating in Illinois under EIA identifier 4362. It reports service to approximately 36,995 customer accounts and generated about $0.09 billion in annual electric revenue, with a service footprint spanning 115 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.
In 2023, the average Corn Belt Energy Corporation customer experienced 392.9 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 4.54, putting the typical customer at roughly 5 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 158.5 minutes; the difference from the headline 392.9 shows how much of the outage total came from weather rather than everyday grid issues.
Corn Belt Energy Corporation 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 314.9 to 392.9 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.

Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
