What short-outage Modesto Irrigation District filings show
Modesto Irrigation District is a municipally-owned utility operating in California under EIA identifier 12745. It reports service to approximately 132,803 customer accounts and generated about $0.40 billion in annual electric revenue, with a service footprint spanning 30 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 Modesto Irrigation District customer experienced 60.1 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 0.60, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 38.6 minutes, and the spread against the headline 60.1 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Modesto Irrigation District, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 51.8 to 60.1 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.
