Slide 24 tells it all. It's not the fault of ANY of the generators. Being frozen and icing is a simple fix - even at $10/mo, it's better than having to install a propane tank in the back yard - for those lucky enough to have a back yard and space for it.
Wrong. This tells the story.

Go down to third graph down - electricity generation by energy source - click the gear in upper right hand corner
Set the date rage from 12 Feb to 20 Feb
The graph will display the energy usage by source. Run your cursor across the graph. It will display the megawatthours for each source.
Along the graph, look at 02/14/2021 2000 CST. There you will see a break down of for each source.
Wind 8,087 MWh
Natural Gas 43798 MWh
Coal 10,829 MWh
Nuclear 5,140 MWh
Now advance 24 hours to 02/15/2012 2000 CST
Wind 649 MWh - down 92%
Natural Gas 30,917 MWh - down 29%
Coal 8,023 MWh - down 26%
Nuclear 3,785 MWh - down 26%
Now you can clearly see that our wind turbines were knocked out by the Arctic blast. This triggered the widespread outage. Natural gas all of sudden was being used to heat freezing Texans' homes. I cranked up my natural gas logs in the fireplace when my lights went out. It kept my home temperature from dropping below 50F. The power companies then were forced to compete against the consumer to get natural gas to their power plants. They needed that natural gas to make up for the 7,438 MWh of wind energy that got knocked out. But they couldn't because Texans were using it to heat their homes. That is the story in a nutshell. Yes, there is a winterization factor that played into the widespread drop of energy production. But it was that proportional drop of wind energy is what triggered the entire blackout event.
Next time, we will know better to make sure our coal and nuclear are boosted for the next Arctic blast.
