Do I have to switch providers?

No, you don't have to do anything and you will remain stay with your current affiliate retail electric provider.

Even if you don't make a switch to another provider, do the research and find out your options. Maybe you don't want to switch and want to stay with your current electric provider but would like to purchase cleaner renewable electricity. Chances are, your current electric company offers a renewable energy product for your home. That's what deregulation is about - the consumer having options.
