Their average residential prices ran from 11.01¢ to 17.90¢ per kilowatthour, with a median of 13.76¢, against a Iowa average of 13.40¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Iowa customers, not for this county alone.
The median SAIDI they reported was 116.3 minutes per customer including major event days; the median among all Iowa utilities reporting was 85.7.
The Census Bureau estimates the county's population at 20,883. 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 Iowa operation; EIA publishes nothing at county level.
