Where Delmarva Power sits
It serves 172,008 residential customers in Maryland. Its 20.22¢ per kilowatt-hour sits 7.1% below the Maryland average of 21.77¢.
Consumption is close to the national norm at 943 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 79 minutes without electricity across 0.68 interruptions. The median across the 941 utilities that report this is 185 minutes.
That is markedly better than typical. Short outage durations usually mean an underground or heavily automated network, and they are expensive to achieve, which is part of why reliable systems often carry higher delivery charges.
Rooftop solar on this system
6,701 residential customers had net-metered solar in 2024, totalling 62.95 megawatts. That works out to 39 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.
