What short-outage Hartford Electric filings show

Hartford Electric is a municipally-owned utility operating in Wisconsin under EIA identifier 8212. It reports service to approximately 7,907 customer accounts and generated about $0.03 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 Hartford Electric customer experienced 29.8 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. Over the same period, SAIFI (outage events per customer) was 0.25, putting the typical customer at roughly 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 0.0 minutes, the gap between that figure and the headline 29.8 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Hartford Electric, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 33.6 down to 29.8 minutes, a trend worth noting for anyone weighing capital investment outcomes.
