Electric utilities serving Mercer County, North Dakota
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
7 utilities list Mercer County, North Dakota, in the service territory they reported to EIA for 2024, the largest by residential customers statewide being Montana-Dakota Utilities Co, Roughrider Electric Cooperativ and Mor-Gran-Sou Electric Coop Inc.
Their average residential prices ran from 7.86¢ to 11.72¢ per kilowatthour, with a median of 10.24¢, against a North Dakota average of 11.51¢ and a US average of 16.48¢. Each price is the utility's figure for all of its North Dakota customers, not for this county alone.
Basin Electric Power Coop and WAPA: Western Area Power Administration list the county too but reported no residential sales in North Dakota under their own name.
The median SAIDI they reported was 170.0 minutes per customer including major event days; the median among all North Dakota utilities reporting was 95.7.
The Census Bureau estimates the county's population at 8,441. 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 North Dakota operation; EIA publishes nothing at county level.
