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 — a metric called SAIDI (System Average Interruption Duration Index). 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 3.92 for the same period, so customers statistically faced roughly 4 distinct interruptions that year.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Kauai Island Utility Cooperative, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 57.4 to 248.8 minutes, which may reflect either worsening weather exposure or delayed grid modernization. All figures on this page come directly from EIA Form 861, the federal annual electric power industry survey, with service territory ZIPs sourced from OpenEI — you can cross-reference them with your own utility bill or use them when comparing providers before relocating.
