What short-outage Decatur Utilities filings show

Decatur Utilities is a municipally-owned utility operating in Alabama under EIA identifier 4958. It reports service to approximately 26,904 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 4 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.

In 2023, the average Decatur Utilities customer experienced 66.4 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 0.94, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 66.4 minutes, the gap between that figure and the headline 66.4 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Decatur Utilities, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 77.0 to 66.4 minutes across that span, a direction regulators and prospective customers tend to watch closely.
