Maryland residents are now able to choose who supplies their electricity. (Customers of municipal electric systems and some rural cooperative systems are the exceptions - see "Areas not participating.") Your local utility, now called your electric company, will still deliver the electricity to your home, but you can choose another company to generate the electricity, if other companies are making an offer in your area.
Every state that is deregulated requires their electricity providers to be licensed or certified by the state in order to sell electricity. Your state’s public utility commission website keeps an up to date list of these electricity providers so that you can be certain that you are purchasing electricity from an authorized electricity provider. All of the electricity providers represented on ElectricityPlans.com are authorized electricity providers in the respective states where they do business.
It’s worth noting that you can switch for free with no exit fee 42-49 days before the end of your contract. Under Ofgem’s standards of conduct, energy firms have to give you between 42 and 49 days’ notice of your tariff ending. You can use this time to decide whether to stick with them, or switch. If you decide to switch, you won’t be charged an exit fee.
