Reliability by utility, 2024
SAIDI: minutes of sustained interruption per customer over the year, including major event days (paler bars: the utility reported only the figure without major event days). Median across 4 Hawaii filings: 385.0 minutes with major event days, 253.3 without. EIA's state total: 320.6 and 225.6 minutes, with SAIFI of 2.62 interruptions per customer. Utilities use differing calculation methods, and a single storm can dominate a small utility's year.
