It's not. But ever since the freak blizzard of Feb 2021 where temps got down to as low as -13C (8F) and below 0C for a full week (which was a once in a century type of event for Texas), everyone keeps trying to dog pile on ERCOT for a week of rolling black outs during said blizzard. They were predicting black outs this last summer too and they didn't happen. Black outs happen multiple times a decade in every state I've ever lived in. And these states are all connected to other states but it doesn't stop the black outs from happening. In Florida I've gone two weeks without power after a hurricane. Texas has massive wind farms in the northern part of the state that provide as much as 40% of the power for the state. They were not winterized to handle freezing temps because Texas is a subtropical/semi-arid state that is not supposed to see these kind of temperatures for such a sustained period. Natural gas demand was more than doubled because the wind farms were down and everyone has electric heat pumps in Texas because gas or wood heaters are not needed 99 years out of 100. At any rate if Texas sees another blizzard like '21 anytime soon we're going to have to start to have a conversation about global cooling.
