Northcentral Mississippi E P A is a member-owned electric cooperative operating in Mississippi under EIA identifier 13735. It reports service to approximately 35,107 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 10 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 Northcentral Mississippi E P A customer experienced 405.6 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 3.25 for the same period, meaning customers statistically saw about 3 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 232.8 minutes; the difference from the headline 405.6 shows how much of the outage total came from weather rather than everyday grid issues.
Northcentral Mississippi E P A has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that span, SAIDI rose from 138.0 to 405.6 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
