There were big issues with lack of winterization of conventional powerplants.
There were also gas pipeline issues, a key root cause of which was FedGov over-regulation. Natural gas engines driving the compressors at the pipeline compressor stations fell afoul of NOx regulations, so they were replaced with electric motors. Those don’t work so well when the grid goes down . . .
There were also issues at the natural gas wells supplying the pipelines.
This had many root causes. But too much Green virtue signaling for a long time was certainly one of them.
Ditto on the gas pipelines FP ...... we were failing with low pressures in the panhandle during this wakeup notice from mother nature. I keep 12 cords of oak and hickory secured for my woodstove for warmth, bed tanks on my diesel trucks for fuel shortages and a swimming pool for summer heatwaves. I’m aware of the western , eastern and TEXAS power grids but as all things man made our TEXAS grid infrastructure is eroding due to lack of maintenance over time . There will be more dangerous events due to polidiots and presstitutes personal profit agendas and fly by night BS ideas... .
Plan accordingly to provide for you and yours “alone” .... without for short or long durations if you can .....
Just how I live and learn . My opinion only. Stay Safe !
