What mid-pack PUD No 1 of Snohomish County filings show
PUD No 1 of Snohomish County is a municipally-owned utility operating in Washington under EIA identifier 17470. It reports service to approximately 377,261 customer accounts and generated about $0.67 billion in annual electric revenue, with a service footprint spanning 48 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 PUD No 1 of Snohomish County customer experienced 120.2 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 1.18 for the same period, so customers statistically faced roughly 1 distinct interruption that year. 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.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for PUD No 1 of Snohomish County, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 255.5 to 120.2 minutes across that span, a direction regulators and prospective customers tend to watch closely.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
