PUD No 3 of Mason County
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. Annual figures: Form EIA-861 for 2024, final release. Monthly state figures run to July 2026.
PUD No 3 of Mason County is a public power district that reported 33,975 residential customers in Washington on Form EIA-861 for 2024, with a service territory that touches 4 counties.
Its average residential price that year was 13.79¢ per kilowatthour, 16% above the Washington average of 11.90¢ and 16% below the US average of 16.48¢. The figure is residential revenue divided by residential sales, so it folds in fixed charges, riders and every rate schedule the utility bills under.
That works out to an average residential bill of $156.28 a month on average use of 1,133 kWh a month. Across Washington the average bill was $113.68 on 955 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
For reliability it reported a SAIDI of 519.0 minutes per customer with major event days included and 269.3 minutes with them excluded, calculated under another method. The median among Washington utilities reporting was 255.4 minutes with major event days; this utility's figure is 103% above that median.
The average price is up 28.8% on 2019, against up 22.6% for Washington as a whole, and up 8.6% on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.45¢.

Bundled residential service only in the price, bill and use columns. Bill = residential revenue ÷ customers ÷ 12; use = residential sales ÷ customers ÷ 12. EIA describes its early release as not fully edited; it is shown for this utility alone and enters no average, median or rank on this site.
Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 33,975 | 462 GWh | 68% | $63,717,000 | 13.79¢ |
| Commercial | 2,431 | 177.3 GWh | 26% | $18,198,000 | 10.27¢ |

Customers, sales and revenue count every service type the utility reported (bundled, energy-only and delivery-only). The price column uses bundled service alone, because part-bill revenue would understate it. Sources of energy: 710.3 GWh in total, of which 0% was its own net generation and 710.3 GWh was bought wholesale; summer peak demand 104 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under another method. SAIFI: 2.30 interruptions per customer with major event days, 1.39 without; CAIDI 225.3 minutes per interruption. EIA's Washington total across all reporting utilities was 623.5 minutes with major event days and 158.6 without. Major event days are storms and similar events that a utility's chosen method sets apart; methods differ, so treat comparisons as approximate. What SAIDI and SAIFI mean.
