Probably also has to do with Texas just being the geographically largest of the lower 48. (Alaska is much bigger but its population is very low so they don't use much power.)
Texas also has its own grid [0]. There are three separate grids in the lower 48: East, West, and Texas. This means the Texas grid doesn't need to stay in phase with the rest of the US. While they do move power to/from the other two grids, it's done with DC interties. Texas shares power with Mexico via high-voltage DC transmission lines [1].
