IMO it should be less about compelling them during an emergency as ensuring adequate disaster preparation and grid stability well before an emergency. Not much to do once the damage is already done other than figure out how to ensure it won’t happen again.
Friendly reminder about the event in question: the temperature wasn’t even THAT cold (minimum 0F IIRC). Much of the world deals with ice storms and freezing temperatures without the entire grid failing. I understand a state that deals with heat more than cold being less prepared for ice, but the lesson should need to be learned only once.
Would it not be better to leave it as is to teach others? Censoring serves no purpose here and it would prevent people from learning
