What long-outage Natchez Trace Elec Power Assn filings show

Natchez Trace Elec Power Assn is a member-owned electric cooperative operating in Mississippi under EIA identifier 13227. It reports service to approximately 16,163 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 23 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 Natchez Trace Elec Power Assn customer experienced 675.6 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. SAIFI, the average number of outage events per customer, was 5.75 for the same period, so customers statistically faced roughly 6 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 154.2 minutes, the gap between that figure and the headline 675.6 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Natchez Trace Elec Power Assn, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 683.6 to 675.6 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
