What mid-pack 4-County Electric Power Assn filings show
4-County Electric Power Assn is a member-owned electric cooperative operating in Mississippi under EIA identifier 6641. It reports service to approximately 51,053 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 38 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 4-County Electric Power Assn customer experienced 175.5 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. Over the same period, SAIFI (outage events per customer) was 1.88, putting the typical customer at roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 134.8 minutes; the difference from the headline 175.5 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), 4-County Electric Power Assn's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 236.7 to 175.5 minutes across that span, a direction regulators and prospective customers tend to watch closely.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.
