After spending so much time and energy with energy companies, I figure I should pass this info onto the internet world (within Houston). I am a Centerpoint Energy resident (you don't get to choose the electricity provider you have; it's based on where the electricity is provided). I think Houston is predominantly a Centerpoint energy area (correct me if I'm wrong).
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.
Electric companies buy longer-term contracts so they can hedge their risks when they’re selling long-term electricity plans. Just a week ago, it looked as if wholesale prices would be as high as Texas has seen in the past 15 years, said Ned Ross, director of governmental affairs for Direct Energy, the third biggest seller of electricity in Texas, behind No. 1 NRG and No. 2 TXU. Future prices have retreated recently, but companies buying power for August are still paying at least double what they paid a year ago, according to data from the Electric Reliability Council of Texas, or ERCOT, which oversees the state’s power markets.
On the one hand, long-term, fixed-rate (contract) plans offer stability in pricing. If energy supply costs suddenly go up in your area, you won’t be left paying more than what you bargained for. You’ll have peace-of-mind. If you want to switch out of your contract before it ends with a lower cost plan, you’ll likely face a cancellation fee (early termination fee).
