What short-outage Manitowoc Public Utilities filings show
Manitowoc Public Utilities is a municipally-owned utility operating in Wisconsin under EIA identifier 11571. It reports service to approximately 18,499 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 3 ZIP codes. 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 Manitowoc Public Utilities customer experienced 70.9 minutes of power interruptions, a measure known as SAIDI, or 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. SAIFI, the average number of outage events per customer, was 0.65 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 7.3 minutes, the gap between that figure and the headline 70.9 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Manitowoc Public Utilities, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 32.9 to 70.9 minutes over that window, a shift that can point to 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.
