What This Utility Data Tells You
Magnolia Electric Power Assn is a member-owned electric cooperative operating in Mississippi under EIA identifier 11519. It reports service to approximately 33,064 customer accounts and generated about $0.08 billion in annual electric revenue, with a service footprint spanning 22 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 Magnolia Electric Power Assn customer experienced 2768.4 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.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Magnolia Electric Power Assn, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has increased from 1103.4 to 2768.4 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.
