What long-outage Tallahatchie Valley E P A filings show
Tallahatchie Valley E P A is a member-owned electric cooperative operating in Mississippi under EIA identifier 18447. It reports service to approximately 28,404 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 41 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 Tallahatchie Valley E P A customer experienced 989.1 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That runs well past the 120–180 minute national benchmark, which can reflect storm-exposed terrain, an aging grid, or slower restoration times. SAIFI, the average number of outage events per customer, was 5.30 for the same period, so customers statistically faced roughly 5 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 507.8 minutes; the difference from the headline 989.1 shows how much of the outage total came from weather rather than everyday grid issues.
Tallahatchie Valley E P A has 3 years of continuous EIA reporting on file (2021–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 468.7 to 989.1 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
