What long-outage Liberty Utilities filings show
Liberty Utilities is an investor-owned utility operating in California under EIA identifier 57483. It reports service to approximately 50,030 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 23 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.
In 2023, the average Liberty Utilities customer experienced 264.6 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. SAIFI, the average number of outage events per customer, was 1.97 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 264.6 minutes, and the spread against the headline 264.6 indicates how much weather, versus routine infrastructure, drove the outage total.
Liberty Utilities has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI climbed from 242.7 to 264.6 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.

Price vs. reliability
Where Liberty Utilities sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Liberty Utilities charges more per customer than 11% of them, and is more reliable (lower SAIDI) than 36% of them, placing it in the quadrant where it pays less and is less reliable. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
Revenue per customer: $1,940/year · Latest SAIDI: 264.6 minutes/year.
