Electric utilities serving Thurston County, Washington
Utilities that list the county in their Form EIA-861 service territory for 2024, with each one's average price, bill and outage minutes.
Thurston County, Washington, appears in the Form EIA-861 service territory of 5 utilities for 2024; Puget Sound Energy Inc, PUD No 1 of Grays Harbor County and PUD No 1 of Lewis County are the largest by residential customers statewide.
Their average residential prices ran from 9.48¢ to 14.63¢ per kilowatthour, with a median of 12.52¢, against a Washington average of 11.90¢ and a US average of 16.48¢. Each price is the utility's figure for all of its Washington customers, not for this county alone.
Bonneville Power Administration lists the county too but reported no residential sales in Washington under its own name.
The median SAIDI they reported was 721.6 minutes per customer including major event days; the median among all Washington utilities reporting was 255.4.
The Census Bureau estimates the county's population at 304,261. 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 Washington operation; EIA publishes nothing at county level.
