Power to Choose is a program run by the Public Utility Commission of Texas. Its goal is to protect residents of the state from unfair energy costs and unregulated REPs, as well as develop a strong infrastructure. The program provides an easy to use, online tool that give residents of the state the opportunity to compare rates, plans and other energy options.  Keep in mind though, you really need to read the fine print if you decide to use Power to Choose (or any other service, for that matter).
The ability to make an electric power switch gives Texas energy consumers the freedom to shop and search for a new rate. Texans switch power providers for a number of reasons. You may choose to switch power supply providers because you move to a new utility area that your current retail provider doesn't service. Maybe you switch power providers because you're unhappy with your current provider's level of customer service. Maybe your reason for switching is simply to find a better rate than what you have now. Whatever your reason may be, you have the power to switch electricity providers.
In this free market competing electricity retailers buy electricity wholesale from private power generators to sell at retail to around 85% of Texas residents. The partnership between generators and retailers is governed by the Electric Reliability Council of Texas, or ERCOT, which attempts to balance the power grid’s electricity supply and demand by purchasing small amounts of electricity at 15-minute intervals throughout the day.
