What long-outage Sacramento Municipal Util Dist filings show
Sacramento Municipal Util Dist is a municipally-owned utility operating in California under EIA identifier 16534. It reports service to approximately 656,481 customer accounts and generated about $1.60 billion in annual electric revenue, with a service footprint spanning 149 ZIP codes. As a municipal utility, it is typically governed by a local board or city council and is exempt from federal income tax.
In 2023, the average Sacramento Municipal Util Dist customer experienced 318.2 minutes of power interruptions, a measure known as SAIDI, or 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 1.42 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 75.6 minutes, and the spread against the headline 318.2 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Sacramento Municipal Util Dist, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that span, SAIDI rose from 47.6 to 318.2 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
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.
