In Texas, the average household uses an average of 77 million Btu of electricity per year, which is approximately 14% less than the national average. Breaking these stats down even further shows us that electricity use in the average Texan home is 26% higher than the rest of the United States, however this isn’t much higher than several other states that are closest to Texas. When it comes to cost, the average total household bill per year is $1,801. This amount ranks amongst the highest across America, but other states that typically see soaring temperatures in the summer season aren’t far behind.
The Public Utility Commission (PUC) has a website to help you find and compare all the electricity plans and providers in your area. Visit www.powertochoose.org or call 866-PWR-4-TEX (1-866-797-4839). You can filter your options based on your usage, your preferred plan type, and several other factors. Once you’ve chosen the retail electricity provider that best suits your needs, you can sign up directly from their website.
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.
One desired effect of the competition is lower electricity rates. In the first few years after the deregulation in 2002, the residential rate for electricity increased seven times, with the price to beat at around 15 cents per kilowatt hour (as of July 26, 2006, www.powertochoose.org) in 2006. However, while prices to customers increased 43% from 2002 to 2004, the costs of inputs rose faster, by 63%, showing that not all increases have been borne by consumers. (See Competition and entry of new firms above for discussion on the relationship between retail prices, inputs, and investment.)
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 2002-2014 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. 
Twenty bucks compared to a $2,000 bill? Not much to write home about, but hey — it’s free money. And, true, you’ll still get some free money when you use less energy, but rewards only really seem reward-y if you're shelling out big bucks. That same Direct Energy plan only yields about $6 in Plenti points per year if you use 500 kWh of electricity each month.
