REPs sell electricity rates to Houston energy consumers, but transmission and distribution service providers (TDSPs) deliver the supply of electricity. In Houston, CenterPoint Energy serves as the area's TDSP and works with about 85 REPs. If your power goes out, immediately report the issue to CenterPoint Energy, not your REP. Use the following phone numbers to get in touch with your Houston TDSP.
Should you choose a short-term, long-term, month-to-month, or prepaid plan? The short answer: it depends on your specific needs. How long do you anticipate living at your location? Are you deciding in the peak season (summer in Houston) or off season? All electricity providers in Houston offer a broad selection of plans for different contract lengths. Many also offer month-to-month and prepaid electricity plans. The bottom line is that everyone’s needs are different and all contract term lengths offer advantages and disadvantages.
Customers can find deals in competitive electricity markets if they take the time and effort to look at web sites such as powertochoose.org, the official comparison shopping site of the Public Utility Commission. The study cited a PUC survey of retail electricity offerings in Houston that showed nine deals in March that were lower than the regulated price of electricity in San Antonio.
One way NRG has expanded its customer base — it has about 30 percent of the retail electricity market in Texas compared to about 20 percent a decade ago —is by putting employees into retail settings such as grocery stores and discount stores to meet with consumers about the company’s electricity plan offerings. The face-to-face interactions have helped the company explain the range of current offerings, said Killinger. NRG also emphasizes the importance of buying power from a company with enough financial heft that it will be around in the future.

Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
The increase in retail rates come as companies prepare for surging prices in the wholesale electricity markets where they buy their power. Forecasts of higher than normal temperatures and record power demand are coinciding with the shutdown of at least three coal-fired plants, leading to concerns that temporary shortages on the hottest summer days could send wholesale prices, which typically average less than $50 per megawatt hour, spiking to $3,000 per megawatt hour or higher. (A megawatt hour is 1,000 kilowatt hours.)
The Bayou City is diverse in its population, culture and electricity rates.
