What mid-pack Adams-Columbia Electric Coop filings show
Adams-Columbia Electric Coop is a member-owned electric cooperative operating in Wisconsin under EIA identifier 108. It reports service to approximately 39,141 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 47 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 Adams-Columbia Electric Coop customer experienced 229.1 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 1.09, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 229.1 minutes, the gap between that figure and the headline 229.1 reveals how much weather, not day-to-day infrastructure, drove outages.
Adams-Columbia Electric Coop has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 156.1 to 229.1 minutes, which may reflect either 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.
