The ERCOT "dependable" rating for wind in winter is 7 gigawatts. Granted, there were big problems with natural gas deliveries in last week's conditions to plants that ERCOT counts on for more than 50% of winter capacity in TX.
Failure all around.
I completely disagree.
The major reason natural gas supplies stopped is because the Permian Basin - where most of the just-in-time natural gas in Texas comes from - was one of the first sectors to lose electric power when the Texas grid started to collapse.
No electricity in the Permian Basin means most of the source pipelines and heaters stopped working.
Was that predictable?
Probably.
But the collapse of the Texas power grid was so far out on the risk curve, it would have been almost impossible to get funding to prevent that.
