What short-outage City of Marshfield - (WI) filings show

City of Marshfield - (WI) is a municipally-owned utility operating in Wisconsin under EIA identifier 11740. It reports service to approximately 13,946 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 9 ZIP codes.

In 2023, the average City of Marshfield - (WI) customer experienced 47.3 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. SAIFI, the average number of outage events per customer, was 0.22 for the same period, so customers statistically faced roughly 0 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 12.7 minutes, the gap between that figure and the headline 47.3 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for City of Marshfield - (WI), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 37.9 to 47.3 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
