What short-outage City of Zeeland - (MI) filings show
City of Zeeland - (MI) is a municipally-owned utility operating in Michigan under EIA identifier 21158. It reports service to approximately 6,954 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 1 ZIP code. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.
In 2023, the average City of Zeeland - (MI) customer experienced 33.4 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 0.26, putting the typical customer at roughly 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 13.5 minutes, the gap between that figure and the headline 33.4 reveals how much weather, not day-to-day infrastructure, drove outages.
City of Zeeland - (MI) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI dropped from 66.8 to 33.4 minutes across that span, a direction regulators and prospective customers tend to watch closely.
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.
