What short-outage Alameda Municipal Power filings show
Alameda Municipal Power is a municipally-owned utility operating in California under EIA identifier 207. It reports service to approximately 37,050 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 2 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 Alameda Municipal Power customer experienced 6.7 minutes of power interruptions, a measure known as SAIDI, or 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. Over the same period, SAIFI (outage events per customer) was 0.03, putting the typical customer at roughly 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 6.7 minutes; the difference from the headline 6.7 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Alameda Municipal Power's reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 57.6 to 6.7 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against Alameda Municipal Power's other reported years.
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.
