What long-outage South Central Power Company filings show
South Central Power Company is a member-owned electric cooperative operating in Ohio under EIA identifier 18085. It reports service to approximately 126,200 customer accounts and generated about $0.33 billion in annual electric revenue, with a service footprint spanning 130 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 South Central Power Company customer experienced 541.5 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that falls inside the typical 120–180 minute national benchmark, in line with what most U.S. distribution utilities report. Over the same period, SAIFI (outage events per customer) was 2.31, putting the typical customer at roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 259.1 minutes; the difference from the headline 541.5 shows how much of the outage total came from weather rather than everyday grid issues.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for South Central Power Company, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI climbed from 323.0 to 541.5 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 South Central Power Company sits on price vs. reliability
Among the 781 U.S. utilities large enough to report both revenue per customer and a recent outage record, South Central Power Company charges more per customer than 56% of them, and is more reliable (lower SAIDI) than 19% 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: $2,634/year · Latest SAIDI: 541.5 minutes/year.
