What This Utility Data Tells You

Mid-Carolina Electric Coop Inc is a member-owned electric cooperative operating in South Carolina under EIA identifier 12462. It reports service to approximately 59,829 customer accounts and generated about $0.14 billion in annual electric revenue, with a service footprint spanning 21 ZIP codes.

In 2023, the average Mid-Carolina Electric Coop Inc customer experienced 137.1 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 1.63 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 121.4 minutes, the gap between that figure and the headline 137.1 reveals how much weather, not day-to-day infrastructure, drove outages.

The EIA dataset includes 4 years of continuous reporting (2020–2023) for Mid-Carolina Electric Coop Inc, which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI dropped from 194.9 to 137.1 minutes across that span, a direction regulators and prospective customers tend to watch closely.
