Cullman Electric Coop, Inc is a member-owned electric cooperative operating in Alabama under EIA identifier 4618. It reports service to approximately 47,708 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 22 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.
In 2023, the average Cullman Electric Coop, Inc customer experienced 1155.3 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that exceeds the 120–180 minute national benchmark by a wide margin, a pattern often tied to severe weather exposure, older infrastructure, or longer repair windows. SAIFI, the average number of outage events per customer, was 4.78 for the same period, so customers statistically faced roughly 5 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 563.8 minutes, the gap between that figure and the headline 1155.3 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Cullman Electric Coop, Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 635.0 to 1155.3 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
