Central Electric Power Assn - (MS) is a member-owned electric cooperative operating in Mississippi under EIA identifier 2849. It reports service to approximately 38,637 customer accounts and generated about $0.10 billion in annual electric revenue, with a service footprint spanning 35 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 Central Electric Power Assn - (MS) customer experienced 895.3 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 5.53 for the same period, so customers statistically faced roughly 6 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 263.6 minutes — the gap between that figure and the headline 895.3 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Central Electric Power Assn - (MS), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 572.6 to 895.3 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.

Central Electric Power Assn - (MS) serves 35 ZIP codes in Mississippi.
Central Electric Power Assn - (MS) had a SAIDI of 895.3 minutes in 2023, meaning the average customer experienced about 895 minutes of outages that year. This is above the national average, indicating below-average reliability.
Central Electric Power Assn - (MS) 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 Central Electric Power Assn - (MS) experiences power outages. A lower SAIDI indicates better reliability. The national average is roughly 120-180 minutes per year, so comparing Central Electric Power Assn - (MS)'s SAIDI to that benchmark shows whether this utility is above or below average.
Central Electric Power Assn - (MS) serves approximately 38,637 customers in Mississippi. Customer count can affect reliability metrics because larger utilities may face different infrastructure challenges compared to smaller ones.
Central Electric Power Assn - (MS) has 4 years of reliability data (2020-2023). 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.
