Merced Irrigation District
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.
Merced Irrigation District is a public power district that reported 11,366 residential customers in California on Form EIA-861 for 2024, with a service territory that touches 1 county.
Its average residential price that year was 24.25¢ per kilowatthour, 24% below the California average of 31.97¢ and 47% above 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 $155.60 a month on average use of 642 kWh a month. Across California the average bill was $160.86 on 503 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
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.
The average price is up 45.6% on 2019, against up 66.9% for California as a whole, and down 1.1% on 2023. EIA's early release for 2025, which has not been fully edited, shows 24.15¢.

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 |
|---|---|---|---|---|---|

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: 867.7 GWh in total, of which 36.2% was its own net generation and 553.2 GWh was bought wholesale; summer peak demand 116 MW.

Net generation of 283.6 GWh at power plants this utility operates, from Form EIA-923. It is not the mix delivered to customers: utilities also buy power wholesale (553.2 GWh in 2024), sell generation to others and may co-own plants that another company operates.
