Pretty much yeah. Texas R's refuse to integrate their grid with the fed one which would add new rules to theirs and mandate upgrades which could lead to less outages.
In this particular case there might be a bit of shitey business practice as well.
There is a financial incentive to keep things failure prone, because demand pricing allows them to make the same amount of revenue with whatever (lack of) production is available.

The GOP is a minority party. They use tactics like voter suppression, electoral fraud, and gerrymandering to maintain power, despite receiving votes from q shrinking minority of the populace.
