Electric utilities serving Scott County, Illinois
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
2 utilities list Scott County, Illinois, in the service territory they reported to EIA for 2024, the largest by residential customers statewide being Ameren Illinois Company and Illinois Rural Electric Coop.
Its average residential price was 15.26¢ per kilowatthour, against a Illinois average of 15.87¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Illinois customers, not for this county alone.
The median SAIDI they reported was 223.9 minutes per customer including major event days; the median among all Illinois utilities reporting was 131.9.
The Census Bureau estimates the county's population at 4,866. 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 Illinois operation; EIA publishes nothing at county level.
