I have thought it odd for some time that Texas has its own utility grid that supplies most of the state, apparently having chosen to go it alone, rather than link with either the grid in the Eastern US or the Western US. The word hubris comes to mind.

If a different decision had been made decades ago, I strongly suspect many fewer power outages would have happened, the natural gas that was available could have gone more to where it was needed for heating homes.

ERCOT will be in the hot seat (not dependent on gas or electricity supplies) in the immediate future.

This avoidable disaster makes a very strong argument for doing away with ERCOT, and the go it alone in Texas mindset, and proceed to make the Texas grid interconnected with the grid outside of Texas, and mandating oversight of the Texas portion of the grid by FERC.
