Kauai Island Utility Cooperative

What This Utility Data Tells You

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.
