There is a good piece on Yahoo voices that points out that bad credit can cost you a lot when you are shopping for electricity. It points out that people with decent credit will usually get a good cheap rate without having to put down a deposit. But if you have no credit or poor credit you will probably be rejected by electric providers or asked to provide a deposit. No deposit electricity plans offered by some companies usually have higher rates but they have the benefit of requiring no credit check as part of the signup process. These are often prepaid electricity plans.
