Sonoma Clean Power Authority
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.
Sonoma Clean Power Authority serves 199,002 residential customers in California as a community choice aggregator, according to its 2024 Form EIA-861 filing.
It sells energy only: another company delivers the power and bills for delivery, so the revenue it reports to EIA covers part of each customer's bill. Its energy-only revenue came to 13.04¢ per kilowatthour in 2024, which is not comparable with the bundled California average of 31.97¢.
EIA's reliability file has no SAIDI or SAIFI entry for it in 2024; smaller respondents and energy-only suppliers are not asked for one.

Part-bill revenue per kWh covers energy without delivery, so it is shown beside the state's bundled average for scale only, not as a comparison. 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 | 199,002 | 1 TWh | 48% | $134,263,700 | — |
| Commercial | 28,686 | 943.8 GWh | 44% | $125,759,800 | — |
| Industrial | 2,968 | 159.2 GWh | 7% | $19,373,900 | — |
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: 2.3 TWh in total, of which 0% was its own net generation and 2.3 TWh was bought wholesale; summer peak demand 528 MW.
