What short-outage City of Colton - (CA) filings show
City of Colton - (CA) is a municipally-owned utility operating in California under EIA identifier 4003. It reports service to approximately 19,509 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 9 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 Colton - (CA) customer experienced 0.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. Over the same period, SAIFI (outage events per customer) was 0.00, putting the typical customer at roughly 0 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 0.1 minutes; the difference from the headline 0.1 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 2 years of continuous reporting (2022–2023) for City of Colton - (CA), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 0.3 to 0.1 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 City of Colton - (CA)'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.
