Electric utilities serving Carbon County, Utah
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
3 utilities list Carbon County, Utah, in the service territory they reported to EIA for 2024, the largest by residential customers statewide being PacifiCorp, Price Municipal Corporation and City of Helper.
Its average residential price was 12.52¢ per kilowatthour, against a Utah average of 12.22¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Utah customers, not for this county alone.
The median SAIDI they reported was 117.7 minutes per customer including major event days; the median among all Utah utilities reporting was 106.9.
The Census Bureau estimates the county's population at 20,680. 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 Utah operation; EIA publishes nothing at county level.
