What mid-pack Hawaiian Electric Co Inc filings show
Hawaiian Electric Co Inc is an investor-owned utility operating in Hawaii under EIA identifier 19547. It reports service to approximately 309,292 customer accounts and generated about $2.32 billion in annual electric revenue, with a service footprint spanning 69 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.
In 2023, the average Hawaiian Electric Co Inc customer experienced 149.5 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 1.12 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 115.6 minutes, and the spread against the headline 149.5 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Hawaiian Electric Co Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 95.7 to 149.5 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.
