Yearly outage minutes, on average (2023)
Jo-Carroll Energy, Inc is a member-owned electric cooperative operating in Illinois under EIA identifier 9750. It reports service to approximately 20,253 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 17 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 Jo-Carroll Energy, Inc customer experienced 175.3 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. SAIFI, the average number of outage events per customer, was 0.71 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 31.1 minutes, the gap between that figure and the headline 175.3 reveals how much weather, not day-to-day infrastructure, drove outages.
Jo-Carroll Energy, Inc 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 86.5 to 175.3 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
