Before the Texas Senate Bill 7 (SB7) came into effect on January 1, 2002 electricity consumers didn't have the option to choose who they received electricity from. But now with the Deregulation of Texas Energy, it has broken down the market into several different Retail Electric Providers, helping create competition and lower electricity rates for consumers throughout Texas. Over 75% of Texas has been given the power to choose their own electric provider, and millions of Texans have already exercised their right to choose.
Energy sellers must provide collateral to ERCOT to cover expected future costs of buying wholesale electricity and if the companies don’t have enough capital, they get shut down. Gas And Electric Companies Energy, a Dallas-based electricity retailer that sold wind-energy plans to 9,800 customers including many in the Houston area, got caught in that financial squeeze when it defaulted on its collateral obligations.
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.
