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. 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 Magnolia Electric Power Assn customer experienced 2768.4 minutes of power interruptions, a measure known as SAIDI, or 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.
Magnolia Electric Power Assn has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 1103.4 to 2768.4 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
