What long-outage Mid-South Electric Coop Assn filings show
Mid-South Electric Coop Assn is a member-owned electric cooperative operating in Texas under EIA identifier 12452. It reports service to approximately 39,215 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 82 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 Mid-South Electric Coop Assn customer experienced 409.0 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. The SAIFI figure, which tracks average outage events per customer, came in at 2.20 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 97.0 minutes, the gap between that figure and the headline 409.0 reveals how much weather, not day-to-day infrastructure, drove outages.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for Mid-South Electric Coop Assn, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 202.0 to 409.0 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 Mid-South Electric Coop Assn sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, Mid-South Electric Coop Assn charges more per customer than 83% of them, and is more reliable (lower SAIDI) than 24% 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.
