City of Corona
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.
City of Corona serves 1,285 residential customers in California as a municipal utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 1 county.
Its average residential price that year was 15.50¢ per kilowatthour, 52% below the California average of 31.97¢ and 5.9% 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 $83.24 a month on average use of 537 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.
For reliability it reported a SAIDI of 0.0 minutes per customer with major event days included and 0.0 minutes with them excluded, calculated under IEEE 1366 standard. The median among California utilities reporting was 74.0 minutes with major event days; this utility's figure is 100% below that median.
The average price is up 4.2% on 2019, against up 66.9% for California as a whole, and up 1.6% on 2023. EIA's early release for 2025, which has not been fully edited, shows 15.76¢.

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: 142.9 GWh in total, of which 0% was its own net generation and 142.9 GWh was bought wholesale; summer peak demand 28 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 0.00 interruptions per customer with major event days, 0.00 without. EIA's California total across all reporting utilities was 279.6 minutes with major event days and 158.2 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.
