Actually demand increased and supply decreased, again just facts. The whole state was out of power. The shortfall was significantly greater than the total generated by wind. Since demand increased then wind, since it's a non-dispatched resource that always produced 100% of what it's capable of producing, would mathmatically make up less of the power mix than usual. In which case, wind could never be responsible for more of the shortfall than it was capable of producing in the first place let alone more than a shortfall caused by increased demand. If demand want to 200 then not only could my factory could never be responsible for more than the 16 it was capable of making in the first place but it's now only responsible for 8% of the total even if it drops to 0.You have it backwards. Power availability did not increase in Texas, it declined. So let's stick with your widgets analogy. World production is 100 widgets per unit of time. Your company produces 16 of them, or 16%. Then your widget plant burns down, and world production falls from 100 to 84, down 16%, and your widget plant that used to produce 16% of the world supply is responsible for 100% of the shortfall. It has been a pleasure to enlighten you. No thanks necessary.
And of course, the power grid isn't a widget factory and in reality in Texas fossils fuel plants and even a nuclear plant contributed significantly more to the outages than wind. As would naturally mathmatically be the case when they produce a significantly higher percentage of the power than wind and make up all of the reserve stack.
