Rather than me cobbling something together, someone who actually knows already:
The events of this week also bring to the fore longstanding debates regarding the appropriate generation mix in Texas. Yes, thermal experienced unprecedented outages, but as noted above, it performed both absolutely (measured by capacity utilization) and relatively (measured by decline in utilization) better than wind. Texas would have been better off with less wind and more thermal. Maybe not enough to avoid blackouts altogether, but enough to mitigate substantially their severity.
