Their average residential prices ran from 12.13¢ to 15.54¢ per kilowatthour, with a median of 13.30¢, against a North Carolina average of 14.13¢ and a US average of 16.48¢. Each price is the utility's figure for all of its North Carolina customers, not for this county alone.
The median SAIDI they reported was 123.1 minutes per customer including major event days; the median among all North Carolina utilities reporting was 154.9.
The Census Bureau estimates the county's population at 256,448. 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 North Carolina operation; EIA publishes nothing at county level.
