ERCOT Froze in February 2021. What Happened? Why did it Happen? Can it Happen Again?.

The authors conduct a step-by-step examination of various factors that were blamed for the extended power outage on the ERCOT electricity grid in February 2021. While no single factor fully explains the calamity, the bureaucratic failure in identifying and addressing risks along fuel supply chains was a major failure. Most proposed remedies do not fundamentally address what occurred. The authors make several recommendations, some of which have already been implemented.
