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. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.
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 is substantially above the 120–180 minute national benchmark, indicating either storm-prone geography, aging infrastructure, or extended restoration windows. 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. Excluding major event days (hurricanes, ice storms), SAIDI drops to 507.8 minutes — the gap between that figure and the headline 989.1 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 3 years of continuous reporting (2021–2023) for Tallahatchie Valley E P A, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 468.7 to 989.1 minutes, which may reflect either worsening weather exposure or delayed grid modernization. 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.

Tallahatchie Valley E P A serves 41 ZIP codes in Mississippi.
Tallahatchie Valley E P A had a SAIDI of 989.1 minutes in 2023, meaning the average customer experienced about 989 minutes of outages that year. This is above the national average, indicating below-average reliability.
Tallahatchie Valley E P A is classified as a Cooperative serving Mississippi. Electric cooperatives are member-owned nonprofit utilities, typically serving rural areas.
SAIDI (System Average Interruption Duration Index) measures the average total minutes per year that a customer of Tallahatchie Valley E P A experiences power outages. A lower SAIDI indicates better reliability. The national average is roughly 120-180 minutes per year, so comparing Tallahatchie Valley E P A's SAIDI to that benchmark shows whether this utility is above or below average.
Tallahatchie Valley E P A serves approximately 28,404 customers in Mississippi. Customer count can affect reliability metrics because larger utilities may face different infrastructure challenges compared to smaller ones.
Tallahatchie Valley E P A has 3 years of reliability data (2021-2023). SAIDI has remained relatively stable over this period. Review the trend table above for year-by-year detail.
SAIDI "without major event days" (SAIDI nMED) excludes outages caused by hurricanes, ice storms, and other catastrophic weather events. It better reflects day-to-day infrastructure reliability rather than vulnerability to extreme weather. Both standard SAIDI and SAIDI nMED are shown in the reliability trend table above.
