Is Delmarva Power (Delaware) a monopoly? Can you switch?

For delivery, yes — it's a monopoly. Delmarva Power (Delaware) is the only company that runs the poles and wires to homes in its territory, so you can't pick a different company to deliver your power. That part is a regulated monopoly: Delmarva Power (Delaware), owned by Exelon (Pepco Holdings), can only charge what the DE PSC approves in a rate case.

The electricity itself, though, is open to competition. You can buy your supply from a third-party supplier, or do nothing and stay on Delmarva Power (Delaware)'s default rate — the Standard Offer Service the DE PSC oversees. Switching suppliers doesn't change who delivers your power or who you call during an outage; it only changes the supply line on your bill. And if a supplier is charging more than the Standard Offer Service, you can drop it and return to that regulated rate, usually within one or two billing cycles — no fee to the utility.
