The median SAIDI they reported was 980.9 minutes per customer including major event days; the median among all South Carolina utilities reporting was 733.2.
The Census Bureau estimates the county's population at 114,296. EIA does not publish customers by county, so which utility serves a given address has to be confirmed with the utility or the state utility commission.
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Figures are for each utility's whole South Carolina operation; EIA publishes nothing at county level.
