Electric utilities serving Washtenaw County, Michigan
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
4 utilities list Washtenaw County, Michigan, in the service territory they reported to EIA for 2024, the largest by residential customers statewide being DTE Electric Company, Consumers Energy Co and Village of Chelsea.
Their average residential prices ran from 19.11¢ to 20.13¢ per kilowatthour, with a median of 19.62¢, 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 492.8 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 370,214. 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.
