What long-outage Maui Electric Co Ltd filings show
Maui Electric Co Ltd is an investor-owned utility operating in Hawaii under EIA identifier 11843. It reports service to approximately 73,464 customer accounts and generated about $0.44 billion in annual electric revenue, with a service footprint spanning 19 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 Maui Electric Co Ltd customer experienced 2344.1 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI, the average number of outage events per customer, was 2.56 for the same period, so customers statistically faced roughly 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 213.3 minutes, and the spread against the headline 2344.1 indicates how much weather, versus routine infrastructure, drove the outage total.
Maui Electric Co Ltd 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 235.6 to 2344.1 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.

Price vs. reliability
Where Maui Electric Co Ltd sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Maui Electric Co Ltd charges more per customer than 99% of them, and is more reliable (lower SAIDI) than 2% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
