In 2023, the average City of Huntsville - (AL) customer experienced 65.2 minutes of power interruptions — a metric called SAIDI (System Average Interruption Duration Index). That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. SAIFI — the average number of outage events per customer — was 0.71 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 65.2 minutes — the gap between that figure and the headline 65.2 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for City of Huntsville - (AL), which lets you see whether reliability is trending up or down rather than judging from a single snapshot.
