The median SAIDI they reported was 269.0 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 558,344. 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.
