East Mississippi Elec Pwr Assn

What This Utility Data Tells You

East Mississippi Elec Pwr Assn is a member-owned electric cooperative operating in Mississippi under EIA identifier 5578. It reports service to approximately 13,208 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 38 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 East Mississippi Elec Pwr Assn customer experienced 521.4 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. SAIFI, the average number of outage events per customer, was 4.33 for the same period, so customers statistically faced roughly 4 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 438.3 minutes, and the spread against the headline 521.4 indicates how much weather, versus routine infrastructure, drove the outage total.

East Mississippi Elec Pwr 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 climbed from 251.1 to 521.4 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
