Electric utilities serving Butte County, Idaho
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
Butte County, Idaho, appears in the Form EIA-861 service territory of 3 utilities for 2024; PacifiCorp, Lost River Electric Coop Inc and Bonneville Power Administration are the largest by residential customers statewide.
Its average residential price was 12.11¢ per kilowatthour, against a Idaho average of 11.52¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Idaho customers, not for this county alone.
Bonneville Power Administration lists the county too but reported no residential sales in Idaho under its own name.
The median SAIDI they reported was 264.6 minutes per customer including major event days; the median among all Idaho utilities reporting was 198.9.
The Census Bureau estimates the county's population at 2,783. 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 Idaho operation; EIA publishes nothing at county level.
