The Electric Reliability Council of Texas (ERCOT) does it for you. When you sign up for a plan with a new provider, ERCOT will send you a mailer confirming the switch. You have three days upon receiving the mailer to change your mind. If you don't, you'll have a new provider within seven days, and ERCOT will notify your old provider. Just remember, if you abandon a contract before it's complete, you will be on the hook for any fees or penalties detailed in its Terms of Service.
Prepaid electricity plans are yet another option available to Texas customers. Prepaid plans let you avoid credit checks and deposits by pre-paying for your electricity. Prepaid electricity plans typically do not have a fixed duration and operate on a pay-as-you-go basis. Shopping for prepaid electricity can often yield relatively cheap electricity with no deposit. See Prepaid Electricity: Is It Right For Me? for more.
When you decide to switch, and have got the ball rolling with your new supplier, you should settle any outstanding debts. If you have bills that are more than 28 days old, you might find that you can’t change supplier until you’ve paid them. But there are some exceptions to the 28 days – for example, if you are less than £200 in debt, then your switch could still go ahead as normal
There was a time when electricity was electricity.  Like so many other places around America, in Houston, electricity didn’t mean “cheap electricity”.  But you moved into your home and you called the utility and they turned on the power and the bill came in and you paid it every month.  Oh, sure, you might grumble at the amount but then you’d go around and yell at the kids for leaving the lights on and the TV blaring with nobody in the room or maybe you’d look into buying more energy-efficient appliances.  When it came down to it, the Bill was the Bill.  Either you paid the bill or you ate dry packet meals, had cold showers, and watched TV by peering through the neighbor’s window after dark (preferably once they’d turned the TV on).  What’s that?  You want cheap electricity?  Sure thing:  call 1-800-WHO-CARES any time during regular business hours of 2:17am to 3:04am Sundays only.
