What happens when you choose a new electricity supplier:

1. The new supplier notifies the old supplier and utility that you have changed suppliers.
2. The new supplier transmits utility account information to the utility in order to enroll you as a customer.
3. The utility confirms, by letter to you, of your new supplier selection and the date your new service begins.
4. The actual change of supplier occurs on the meter reading date following a successful enrollment.
