What short-outage City of Vernon filings show

City of Vernon is a municipally-owned utility operating in California under EIA identifier 19798. It reports service to approximately 1,791 customer accounts and generated about $0.20 billion in annual electric revenue, with a service footprint spanning 6 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 City of Vernon customer experienced 29.7 minutes of power interruptions, the industry-standard SAIDI metric (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. The SAIFI figure, which tracks average outage events per customer, came in at 0.53 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 29.7 minutes, and the spread against the headline 29.7 indicates how much weather, versus routine infrastructure, drove the outage total.

With 4 consecutive years of EIA data (2020–2023), City of Vernon's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 38.0 to 29.7 minutes across that span, a direction regulators and prospective customers tend to watch closely.
