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.

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).

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.
