Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
St. Clair County, Michigan, appears in the Form EIA-861 service territory of 1 utility for 2024: DTE Electric Company.
Its average residential price was 20.13¢ per kilowatthour, against a Michigan average of 19.30¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Michigan customers, not for this county alone.
The median SAIDI they reported was 483.0 minutes per customer including major event days; the median among all Michigan utilities reporting was 261.6.
The Census Bureau estimates the county's population at 160,486. 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 Michigan operation; EIA publishes nothing at county level.
