Remember, while you can choose your REP in deregulated areas of Texas, you cannot choose your TDU. The TDU is determined by your geographical location.
Also, keep in mind that not all cities and areas in Texas have electric choice. Some cities, such as Austin, San Antonio, The Woodlands, Beaumont, and El Paso do not have a REP/TDU relationship.
