City of Milford
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 Milford serves 7,169 residential customers in Delaware as a municipal utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 2 counties.
Its average residential price that year was 15.17¢ per kilowatthour, 8.4% below the Delaware average of 16.57¢ and 7.9% 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 $140.99 a month on average use of 930 kWh a month. Across Delaware the average bill was $150.87 on 911 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 20.0 minutes per customer with major event days included and 20.0 minutes with them excluded, calculated under another method. The median among Delaware utilities reporting was 90.1 minutes with major event days; this utility's figure is 78% below that median.
The average price is up 13.8% on 2019, against up 32.0% for Delaware as a whole, and up 6.7% on 2023. EIA's early release for 2025, which has not been fully edited, shows 15.86¢.

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: 248 GWh in total, of which 0% was its own net generation and 255.1 GWh was bought wholesale; summer peak demand 55 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under another method. SAIFI: 0.20 interruptions per customer with major event days, 0.20 without; CAIDI 100.0 minutes per interruption. EIA's Delaware total across all reporting utilities was 116.1 minutes with major event days and 65.9 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.
