What mid-pack MPD Electric Cooperative filings show
MPD Electric Cooperative is a member-owned electric cooperative operating in South Carolina under EIA identifier 66073. It reports service to approximately 38,286 customer accounts and generated about $0.14 billion in annual electric revenue. 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 MPD Electric Cooperative customer experienced 258.3 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, 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 2.02, putting the typical customer at roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 127.2 minutes; the difference from the headline 258.3 shows how much of the outage total came from weather rather than everyday grid issues.
Only a single year of reliability data is available, so multi-year trend analysis is not yet possible for MPD Electric Cooperative.
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 MPD 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, MPD Electric Cooperative charges more per customer than 89% of them, and is more reliable (lower SAIDI) than 37% 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.
Revenue per customer: $3,554/year · Latest SAIDI: 258.3 minutes/year.
