What short-outage Florence Utility Comm filings show

Florence Utility Comm is a municipally-owned utility operating in Wisconsin under EIA identifier 6424. It reports service to approximately 1,596 customer accounts and generated about $0.00 billion in annual electric revenue, with a service footprint spanning 1 ZIP code. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.

In 2023, the average Florence Utility Comm customer experienced 21.4 minutes of power interruptions, a measure known as SAIDI, or 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 0.22, putting the typical customer at roughly 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 21.4 minutes, the gap between that figure and the headline 21.4 reveals how much weather, not day-to-day infrastructure, drove outages.

Florence Utility Comm has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that window, SAIDI moved from 143.2 down to 21.4 minutes, a trend worth noting for anyone weighing capital investment outcomes. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Florence Utility Comm's other reported years.
