What short-outage Willmar Municipal Utilities filings show
Willmar Municipal Utilities is a municipally-owned utility operating in Minnesota under EIA identifier 20737. It reports service to approximately 10,164 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 1 ZIP code. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average Willmar Municipal Utilities customer experienced 88.5 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. Over the same period, SAIFI (outage events per customer) was 1.75, putting the typical customer at roughly 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 40.0 minutes, the gap between that figure and the headline 88.5 reveals how much weather, not day-to-day infrastructure, drove outages.
Willmar Municipal Utilities 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 22.2 to 88.5 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.
