NERC created a report after the Texas 2011 ice storm power outage with recommendations for ERCOT generators to improve their weatherization standards [0]. In that report they referenced not only the 2011 incident but previous incidents where the grid generators failed to adequately prepare for potential problems due to weather related issues.

In the 2021 storm, hundreds of people died. Comeuppance is not the right word. I don't know the right one, but I believe it's closer to willful blindness or predatory delay.
