Not all parts of Texas have the power to choose their electric provider.  TrueCost indexes electric rates where there is choice, but does not include prices for Austin (Austin Energy), San Antonio (CPS Energy), El Paso (El Paso Electric), northeast Texas (SWEPCO) or other areas served by a single provider.
