South Central Power Company

What This Utility Data Tells You

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.
