What short-outage City of Seattle - (WA) filings show
City of Seattle - (WA) is a municipally-owned utility operating in Washington under EIA identifier 16868. It reports service to approximately 503,221 customer accounts and generated about $1.05 billion in annual electric revenue, with a service footprint spanning 62 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average City of Seattle - (WA) customer experienced 95.7 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). 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 0.60 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 95.7 minutes, and the spread against the headline 95.7 indicates how much weather, versus routine infrastructure, drove the outage total.
City of Seattle - (WA) has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI climbed from 79.6 to 95.7 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
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.
