What long-outage Eastern Illinois Elec Coop filings show

Eastern Illinois Elec Coop is a member-owned electric cooperative operating in Illinois under EIA identifier 5585. It reports service to approximately 13,502 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 117 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 Eastern Illinois Elec Coop customer experienced 613.9 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 2.06 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 110.1 minutes, the gap between that figure and the headline 613.9 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Eastern Illinois Elec Coop's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 148.9 to 613.9 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
