What short-outage Turlock Irrigation District filings show
Turlock Irrigation District is a municipally-owned utility operating in California under EIA identifier 19281. It reports service to approximately 95,053 customer accounts and generated about $0.32 billion in annual electric revenue, with a service footprint spanning 22 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average Turlock Irrigation District customer experienced 80.0 minutes of power interruptions, the industry-standard SAIDI metric (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 0.74, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 61.0 minutes, the gap between that figure and the headline 80.0 reveals how much weather, not day-to-day infrastructure, drove outages.
With 4 consecutive years of EIA data (2020–2023), Turlock Irrigation District's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 75.0 to 80.0 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
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.
