Electric utilities serving Apache County, Arizona
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
Apache County, Arizona, appears in the Form EIA-861 service territory of 4 utilities for 2024; Arizona Public Service Co, Navopache Electric Coop, Inc and Navajo Tribal Utility Authority are the largest by residential customers statewide.
Their average residential prices ran from 13.43¢ to 16.63¢ per kilowatthour, with a median of 16.45¢, against a Arizona average of 14.91¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Arizona customers, not for this county alone.
WAPA: Western Area Power Administration lists the county too but reported no residential sales in Arizona under its own name.
The median SAIDI they reported was 296.9 minutes per customer including major event days; the median among all Arizona utilities reporting was 113.2.
The Census Bureau estimates the county's population at 64,445. 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 Arizona operation; EIA publishes nothing at county level.
