City of Holland is a municipally-owned utility operating in Michigan under EIA identifier 8723. It reports service to approximately 30,855 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 2 ZIP codes. 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 City of Holland customer experienced 46.8 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). 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 0.70, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 30.8 minutes; the difference from the headline 46.8 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), City of Holland's reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 46.1 to 46.8 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
