In 2023, the average City of Plymouth - (WI) customer experienced 28.5 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 0.38 for the same period, meaning customers statistically saw about 0 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 0.0 minutes, and the spread against the headline 28.5 indicates how much weather, versus routine infrastructure, drove the outage total.

With 2 consecutive years of EIA data (2022–2023), City of Plymouth - (WI)'s reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 25.3 to 28.5 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
