What long-outage Southern Pine Electric Cooperative filings show
Southern Pine Electric Cooperative is a member-owned electric cooperative operating in Mississippi under EIA identifier 17647. It reports service to approximately 70,323 customer accounts and generated about $0.22 billion in annual electric revenue, with a service footprint spanning 65 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.
In 2023, the average Southern Pine Electric Cooperative customer experienced 1625.1 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, 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 5.21 for the same period, so customers statistically faced roughly 5 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 316.9 minutes; the difference from the headline 1625.1 shows how much of the outage total came from weather rather than everyday grid issues.
Southern Pine Electric Cooperative 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 1203.3 to 1625.1 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
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.

Price vs. reliability
Where Southern Pine Electric Cooperative sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Southern Pine Electric Cooperative charges more per customer than 79% of them, and is more reliable (lower SAIDI) than 3% of them, placing it in the quadrant where it pays more but is LESS reliable, a premium price without a reliability payoff. Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
