Electric utilities serving Woodbury County, Iowa
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
Woodbury County, Iowa, appears in the Form EIA-861 service territory of 7 utilities for 2024; MidAmerican Energy Co, North West Rural Electric Coop and Western Iowa Power Coop are the largest by residential customers statewide.
Their average residential prices ran from 9.26¢ to 11.01¢ per kilowatthour, with a median of 10.14¢, 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 132.2 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 106,649. 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.
