Sadly being an oil n gas man the over reliance on gas is the problem here. Production crashed due to a number of factors from the well heads to the power plants and once the cascade stated 40,000 megawatts of power tripped off line. Texas lost a slew of.gas plants , one of four nuclear reactors went down due to cooling system freezing, and large coal went down for cooling towers freezing. The plant operators didn’t winterized them to take single digits temps which are once in a century rare in the parts of the state where the plants failed.

While methane doesn’t freeze until minus 273 degrees the water that is produced with it at the well head does and the gathering lines are plastic on the surface which during normal Texas winter’s rarely freezes due to the high salt.content and 100_130f temps out the earth but in single.digits over days time the ground cold sinks and the lines freeze.
I used to think Texas was sort of cool.
Here in frozen Michigan you only have to dig a few feet down to protect against freezing regardless of how bad the winter. In your 100 - 130 degree Texas I'll bet you don't freeze one or two inches under.
