The Texas grid which is separate from the rest of the US has a size issue with balancing and peaking that ha shown up from time to time. Their grid collapse a few winters ago would (probably) not have happened if they were connected to the big grid like everyone else is.
There are two other US grids, the Eastern and Western Interconnects. They are not frequency synchronized, and there are minimal AC-DC-AC interties connecting them.
The big collapse in Texas involved about 30GW of generation going off line. Even if Texas were connected to the Eastern grid, it is unlikely that there would have been 30GW of spare capacity and 30GW of available transmission to draw on.
Perhaps relevant, ERCOT and the Texas PUC have approved the Southern Spirit 3GW HVDC transmission line that would connect ERCOT and the western edge of the TVA's transmission network. The other states that would be affected have refused to approve the project because they believe Texas will screw them over and drive their electricity prices up.
