The median SAIDI they reported was 158.3 minutes per customer including major event days; the median among all California utilities reporting was 74.0.
The Census Bureau estimates the county's population at 53,160. 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 California operation; EIA publishes nothing at county level.
