How Deregulated Electricity Works in Delaware

Delaware deregulated its electricity market in 1999. The system operates with three components: power companies generate electricity (generation), utilities maintain high-voltage lines (transmission), and your local utility (Delmarva Power) delivers electricity to your home (distribution).

You can choose your electricity supplier from 29 competing providers. If you don't select a supplier, you automatically receive default service through your utility at a regulated rate.
