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

City of Stoughton - (WI) is a municipally-owned utility operating in Wisconsin under EIA identifier 18181. It reports service to approximately 9,232 customer accounts and generated about $0.02 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 City of Stoughton - (WI) customer experienced 89.6 minutes of power interruptions, the industry-standard SAIDI metric (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. The SAIFI figure, which tracks average outage events per customer, came in at 0.79 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 36.4 minutes, the gap between that figure and the headline 89.6 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), City of Stoughton - (WI)'s reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 61.5 to 89.6 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
