City of Troy - (AL) is a municipally-owned utility operating in Alabama under EIA identifier 19225. It reports service to approximately 9,458 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 3 ZIP codes.

In 2021, the average City of Troy - (AL) customer experienced 43.1 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 0.84 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 24.9 minutes — the gap between that figure and the headline 43.1 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 2 years of continuous reporting (2020–2021) for City of Troy - (AL), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. 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.
