What mid-pack Kauai Island Utility Cooperative filings show
Kauai Island Utility Cooperative is a member-owned electric cooperative operating in Hawaii under EIA identifier 10071. It reports service to approximately 35,173 customer accounts and generated about $0.17 billion in annual electric revenue, with a service footprint spanning 17 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.
In 2023, the average Kauai Island Utility Cooperative customer experienced 248.8 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 3.92 for the same period, meaning customers statistically saw about 4 distinct interruptions that year.
With 4 consecutive years of EIA data (2020–2023), Kauai Island Utility Cooperative's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 57.4 to 248.8 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 Kauai Island Utility Cooperative sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Kauai Island Utility Cooperative charges more per customer than 96% 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: $4,823/year · Latest SAIDI: 248.8 minutes/year.
