Due to the increased usage of natural gas immediately after deregulation, new-era energy tools such as wind power and smart-grid technology were greatly aided. Texas' first "renewable portfolio standard" — or requirement that the state's utilities get a certain amount of their power from renewable energy like wind — was signed into law in 1999, as part of the same legislation that deregulated the electric market.
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. 
The price to beat seemed to accomplish its goal of attracting competitors to the market during the period through January 1, 2007. It allowed competitors to enter the market without allowing the incumbents to undercut them in price. It has also given energy consumers the ability to compare energy rates offered by different providers. The less-regulated providers undercut the price to beat by only a small margin given that they must balance lower prices (to attract customers and build market share) with higher prices (needed to reinvest in new power plants). Due to the small difference in competing prices and slow (yearly or so) "buying" process, price decrease due to competition was very slow, and it took a few years to offset the original increase by "traditional" electric providers and move to lower rates.
