City of Pasadena - (CA) is a municipally-owned utility operating in California under EIA identifier 14534. It reports service to approximately 66,719 customer accounts and generated about $0.23 billion in annual electric revenue, with a service footprint spanning 35 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 City of Pasadena - (CA) customer experienced 18.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. Over the same period, SAIFI (outage events per customer) was 0.22, putting the typical customer at roughly 0 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 18.1 minutes, and the spread against the headline 18.1 indicates how much weather, versus routine infrastructure, drove the outage total.
With 4 consecutive years of EIA data (2020–2023), City of Pasadena - (CA)'s reliability record can be judged on trend rather than one isolated year. SAIDI has improved from 35.9 to 18.1 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
