Maui Electric Co Ltd

What This Utility Data Tells You

Maui Electric Co Ltd is a investor-owned utility operating in Hawaii under EIA identifier 11843. It reports service to approximately 73,464 customer accounts and generated about $0.44 billion in annual electric revenue, with a service footprint spanning 19 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.

In 2023, the average Maui Electric Co Ltd customer experienced 2344.1 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. SAIFI — the average number of outage events per customer — was 2.56 for the same period, so customers statistically faced roughly 3 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 213.3 minutes — the gap between that figure and the headline 2344.1 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Maui Electric Co Ltd, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 235.6 to 2344.1 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.
