Hawaii Electric Light Co Inc

What This Utility Data Tells You

Hawaii Electric Light Co Inc is an investor-owned utility operating in Hawaii under EIA identifier 8287. It reports service to approximately 89,202 customer accounts and generated about $0.46 billion in annual electric revenue, with a service footprint spanning 32 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.

In 2023, the average Hawaii Electric Light Co Inc customer experienced 245.9 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 2.61 for the same period, so customers statistically faced roughly 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 209.6 minutes, and the spread against the headline 245.9 indicates how much weather, versus routine infrastructure, drove the outage total.

With 4 consecutive years of EIA data (2020–2023), Hawaii Electric Light Co Inc's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 128.8 to 245.9 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
