This is a one off. Learn from it and make the best decision. Three things can go wrong; people, process or technology. This was technology. Does The risk of not fixing this cost more than the circumstances?
I don't think it is yet clear on what went wrong. Why was the decision made to shut down a major Texas nuke plant for repairs in February, rather than, say March or April?
What was the lower temperature limit specified in the contract to build the wind turbines that froze? Did critical infrastructures (e.g., water plants and nat. gas delivery plants) have adequate backup generators, especially in the latter case run by nat. gas)?
Did the failure to carry out rolling outages over a 3+ day period cause water pipes to crack in thousands of homes and in some water mains?
Are the problems Texas citizens face today with having to boil water, long lines at the few stores that are opened, limited truck delivery of supplies to those stores, and panic buying simply part of the cascade of problems caused by a few initial bad decisions that could have been prevented or reduced by competent review and management by energy decisionmakers?
Will the investigations by the Texas legislature uncover the answers and correct deficiencies, or paper them over with verbose, blame-diluting reports and quickly made-up regulations that have their own unintended consequences?
Today I am underenthused that real positive changes will be made.
