My understanding is that the amount of water vapor in the natural gas going through the pipelines was high enough to be a problem at very low temperatures, thus the clogs were dependent upon the freezing temperature of water, not the gas itself.

Pipeline natural gas is dried to a maximum water content of seven pounds per million standard cubic feet. That works out to about 0.014 mole percent. It has a dew point of -40 F (-40 C). It is unlikely that water froze in the natural gas pipeline and contributed to the grid failure.

So I read somewhere froze at the wellhead.

It also froze at the condensate units themselves. Although I haven't heard anything specifically, but pressures tend to decrease with temperature. Refineries produce natural gas, Those plants had problems.

Most catastrophes aren't the result of a single point of failure but are the result of multiple smaller incidents that combine together to create a much larger failure.
