Electrical Dist No3 Pinal 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.
Electrical Dist No3 Pinal County is a public power district that reported 32,009 residential customers in Arizona on Form EIA-861 for 2024, with a service territory that touches 1 county.
Its average residential price that year was 13.93¢ per kilowatthour, 6.6% below the Arizona average of 14.91¢ and 15% 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 $164.72 a month on average use of 1,182 kWh a month. Across Arizona the average bill was $160.24 on 1,075 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 132.4 minutes per customer with major event days included and 85.9 minutes with them excluded, calculated under IEEE 1366 standard. The median among Arizona utilities reporting was 113.2 minutes with major event days; this utility's figure is 17% above that median.
The average price is up 3.1% on 2019, against up 20.0% for Arizona as a whole, and up 1.2% on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.02¢.

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

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: 911.8 GWh in total, of which 0% was its own net generation and 911.8 GWh was bought wholesale; summer peak demand 260 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 1.55 interruptions per customer with major event days, 1.24 without; CAIDI 85.4 minutes per interruption. EIA's Arizona total across all reporting utilities was 87.5 minutes with major event days and 72.0 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.
