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. Switch Energy 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.
You can sort, filter, and shop by pricing at YOUR specific usage level, which lets you shop and compare electricity plans based on the rates you’ll actually experience on your bill, inclusive of hidden fees and taxes. This ensures you’re not misled by the cheaper rates often advertised by electric providers…those “teaser rates” associated with higher usage levels that many households never enjoy because their usage level never reaches that pricing tier.
The growth in wind power and natural gas fueled power will offset the loss in coal over time but for the summer of 2018, expected record demand for electricity will converge with power plant closures to put a squeeze on wholesale electricity rates. This, in turn, will cause the retail electricity prices paid by most Texas consumers to increase. The rise in wholesale rates could be particularly dangerous for consumers who have electricity plans that are tied directly to the wholesale price of electricity.
With a population of over 28 million and growing, Texas is one of the most highly inhabited states in the US. In order to power the homes and businesses within it, Texas produces more electricity than any other state, using roughly 400,000 million kilowatt-hours and enabling residents to consume billions of dollars worth of electricity. As of 2002, the Texas electricity market was deregulated, allowing residents to select their own electricity provider from one of the numerous service companies.
Compared to the rest of the nation, data from the U.S. Energy Information Administration which publishes annual state electric prices  shows that Texas' electric prices did rise above the national average immediately after deregulation from 2003 to 2009, but, from 2010 to 2015 have moved significantly below the national average price per kWh, with a total cost of $0.0863 per kWh in Texas in 2015 vs. $0.1042 nationally, or 17 percent lower in Texas. Between 2Best Electric the total cost to Texas consumers is estimated to be $24B, an average of $5,100 per household, more than comparable markets under state regulation. 
Variable Rate Plans: Designed as month-to-month contracts, these plans are in total control of your energy provider, which can shift the price you pay per kWh at its discretion. This means you, the consumer, are in a better place to reap the benefits when the energy market falls — but it also means you're at risk for hikes in prices, whether as a result of natural disasters or the provider's bottom line. Variable plans always offer a full year of price history to show the average price per kWh so you can get a sense of what you're getting into (like this one from Cheapest Electric Company) and know this: Variable plans don't have cancellation fees. You can cut your service at any time — a huge incentive for Compare Electricity Rates to keep their prices reasonable.
Utility companies are responsible for transmission and delivery of electricity even in energy deregulated parts of Texas and should be contacted in the event of a power outage. Your retail energy supplier may provide you competitive electric rates or exceptional customer service, but they cannot repair power lines or restore your service.
