I am sure that a complete report will be made soon. The renewable sources failed because they were not winterized. The windmills were not equipped with the type of blades that shred off ice. These were options that the State had when they were purchased and turned down. The natural gas burning plants were partially shut down because of lack of winterizing which stalled the gas flow to the generators. And there were many sub-stations which had transformers and switching systems that were not winterized and could not stand up to prolonged cold.
The big mistake that people are making is that Texas has the same equipment that cold states up north or in the east have. And that is false. Ten years ago after Texas had a major ice storm the federal government did a survey and wrote a 300 page report. And that report clearly stated that if Texas did not take steps to winterize certain systems they might fail under cold conditions. And it sure seems that they were correct.
