Duquesne Light Co
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.
Duquesne Light Co is an investor-owned utility that reported 550,405 residential customers in Pennsylvania on Form EIA-861 for 2024, with a service territory that touches 3 counties.
Its average residential price that year was 21.74¢ per kilowatthour, 22% above the Pennsylvania average of 17.77¢ and 32% 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 $131.53 a month on average use of 605 kWh a month. Across Pennsylvania the average bill was $145.17 on 817 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
The price covers the 434,171 residential customers on bundled service. A further 116,234 take delivery only and buy their energy from another supplier; EIA collects just part of their bill from this respondent, so they are left out of the average.
For reliability it reported a SAIDI of 188.0 minutes per customer with major event days included and 127.0 minutes with them excluded, calculated under another method. The median among Pennsylvania utilities reporting was 212.0 minutes with major event days; this utility's figure is 11% below that median.
The average price is up 35.7% on 2019, against up 28.8% for Pennsylvania as a whole, and down 1.5% on 2023.

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: 4.5 TWh in total, of which 0% was its own net generation and 4.5 TWh was bought wholesale; summer peak demand 2,691 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under another method. SAIFI: 0.99 interruptions per customer with major event days, 0.82 without; CAIDI 189.9 minutes per interruption. EIA's Pennsylvania total across all reporting utilities was 336.1 minutes with major event days and 131.0 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.
