In 2023, the average PUD No 1 of Snohomish County customer experienced 120.2 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index).

Strip out major event days (hurricanes, ice storms) and SAIDI falls to 111.9 minutes; the difference from the headline 120.2 shows how much of the outage total came from weather rather than everyday grid issues.
