Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
Big Stone County, Minnesota, appears in the Form EIA-861 service territory of 4 utilities for 2024; Otter Tail Power Co, Agralite Electric Coop and Traverse Electric Coop, Inc are the largest by residential customers statewide.
Their average residential prices ran from 11.33¢ to 13.94¢ per kilowatthour, with a median of 12.64¢, against a Minnesota average of 15.45¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Minnesota customers, not for this county alone.
The median SAIDI they reported was 111.6 minutes per customer including major event days; the median among all Minnesota utilities reporting was 76.7.
The Census Bureau estimates the county's population at 5,054. 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 Minnesota operation; EIA publishes nothing at county level.
