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.
Texas deregulation began in early 2002 with the approval of Texas Senate Bill Number 7. Now, the majority of the state, including Houston, has the power to select their own provider. Previously, consumers were only given one option for an energy supplier. Deregulation has allowed competition in the energy market and has given residents the power to choose which energy provider sells them energy and bills them each month.

The low teaser rates for consumers available just a month ago have disappeared, making it impossible for buyers who average about 1,000 kilowatts a month to lock in a three-month rate for less than 18 cents a kilowatt-hour, according to PowertoChoose.org, the price comparison tool run by the Public Utility Commission of Texas. A year ago, Texans shopping for a three-month contract could find rates that were less than 7 cents a kilowattt hour while earlier this spring, bargains were still available for less than a nickel a kilowatt hour.
​2013	​On March 14, CenterPoint Energy announced it was teaming up with ArcLight Capital Partners LLC and Oklahoma City-based OGE Energy Corp.

Oncor, the state’s largest distribution utility which covers Dallas, Fort Worth and much of North Texas, has already agreed to pass all of the millions of dollars of expected tax savings along to consumers.  Oncor agreed to pass the savings along to customers as part of a rate review which is a formal process in which the PUC reviews the appropriateness of rates being charged by the utility.  No exact details have been determined with respect to how the savings will be passed along. The rate review was actually completed before the tax reform bill was passed but there was a commitment in principle to passing along the savings.  It’s not yet know exactly how much Oncor will save from the lower corporate tax rates but with a $245 million tax bill in 2017 future saving are likely to be in the tens of millions of dollars.
Texas electricity deregulation has given millions of Houston residents and businesses the power to choose the cheapest electricity rate. According to ERCOT, over 92% of Texas homes and businesses who live in deregulated areas have switched electric companies since deregulation began in 2002. Even though electric choice in Texas has been hugely successful for energy savings, customers are still confused by the options, terminology, and overall process of switching electric providers.
Texas currently produces and consumes more electricity than any other state in the country. This energy consumption is due to its size, but the ample land makes it a major producer of wind power – a renewable, or green, energy source. The environmentally friendly energy created by wind power is available to many Texas residents to supply the electricity in their home or business.
Knowing how much electricity you use each month is important to finding the cheapest electricity plan. For Houstonians, usage is typically the lowest in the winter and highest in the summer. Your specific usage levels can be determined by simply looking back at previous electric bills and finding the kWh used. To avoid electric bill surprises during the peak summer months, you’ll need to accurately know your peak electricity usage which typically occurs in August.
If you’re looking for a new electricity deal, you’re not alone: 319,000 electricity customers switched energy supplier during January 2018, according to OFGEM*. Shopping around for the best electricity deal is simpler than you might think – but there are bound to be a few questions. Here’s everything you ever wanted to know about comparing electricity deals.
Keeping on top:  With deregulation, a whole host of electric resellers jumped into the market because there’s a whole lot of electricity to sell:  if Texas were a country, it’d be the 11th largest electricity consumer in the world!  Just by itself, it uses as much electricity as Spain or Great Britain!  That means there’s a whole lot of information you have to find, absorb, and process to make sure you’re getting the best rate for your needs.
Ultimately, analysts said, this means that the vast majority of customers are not reaping the benefits of electricity deregulation, which promised that more competition would mean healthy savings. One analyst estimates that consumers are leaving about $2 billion a year on the table, which is likely flowing to the bottom lines of retail electricity companies.
Texas consumers can save hundreds of dollars each year by shopping for electricity, but most don’t seek out better deals, overwhelmed by the number and complexity of power plans on the state’s Power to Choose website, wary of fine print in too-good-to-be true offers, or just too busy to spend time calculating whether free nights and weekends offset the higher rates they pay during the week.
Using an average of 1,063 kWh of power each month, Houston’s energy consumption rates exceed the national average by over 100 kWh. As a city however, it does manage to maintain a lower monthly energy charge than the rest of the US, incurring an average fee of $99 in comparison to the $112 national monthly average. To further save on their plans each month, residents can choose from a selection of Texas-based energy suppliers and service plans.
