Where Delmarva Power sits
It is the dominant supplier in Delaware, serving 275,018 residential customers, so its pricing effectively sets what the state average looks like. Its 17.23¢ per kilowatt-hour sits 11.1% below the Delaware average of 19.38¢.
Consumption is close to the national norm at 884 kilowatt-hours a month against 871, so the rate translates fairly directly into the bill.
A shareholder-owned company whose rates are set by the state regulator, including an approved return on the capital it has invested. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

How often the power goes out
In 2024 the average Delmarva Power customer went 127 minutes without electricity across 0.77 interruptions. The median across the 941 utilities that report this is 185 minutes.
That is better than the typical American utility, though the figure includes major storm days and can move sharply from one year to the next.
Rooftop solar on this system
9,678 residential customers had net-metered solar in 2024, totalling 76.65 megawatts. That works out to 35.2 installations per thousand customers, against a median of 8 across the utilities reporting it.
Adoption here is exceptionally high. That usually means some combination of a high retail rate worth displacing, strong sunshine and favourable export rules, and it tends to bring its own regulatory argument about who covers the fixed cost of the network. What exports are actually worth.
