What mid-pack Hawaii Electric Light Co Inc filings show
Hawaii Electric Light Co Inc is an investor-owned utility operating in Hawaii under EIA identifier 8287. It reports service to approximately 89,202 customer accounts and generated about $0.46 billion in annual electric revenue, with a service footprint spanning 32 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 Hawaii Electric Light Co Inc customer experienced 245.9 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. SAIFI, the average number of outage events per customer, was 2.61 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 209.6 minutes, and the spread against the headline 245.9 indicates how much weather, versus routine infrastructure, drove the outage total.
With 4 consecutive years of EIA data (2020–2023), Hawaii Electric Light Co Inc's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 128.8 to 245.9 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 Hawaii Electric Light Co Inc sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Hawaii Electric Light Co Inc charges more per customer than 97% of them, and is more reliable (lower SAIDI) than 38% 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.
Revenue per customer: $5,136/year · Latest SAIDI: 245.9 minutes/year.
