Ok, but the cost of the outages far exceeds the cost of buying antifreeze for the facilities that failed, even when averaged over the years between failures (and this has happened so often, we have that data).
The reason it hasn’t been fixed is that the ercot market (which is an artificial, legislated thing) is intentionally structured so that the production facilities make unbounded profit during correlated failures.
I say “intentionally” because this keeps happening and the legislature explicitly refuses to fix it. There is no better proof than that.
One simple solution, assuming you don’t like legislating technical fixes, which I don’t like either, is to fine the shit out of them during correlated failures. For example (real legislation would hopefully be better):
100% of money in the market during months with more than a 10% peak outage would go to the game and wildlife service, or some other popular Texas thing, and they could establish criminal liability for intentionally curtailing production during power shortages. So, when this happens, costs go to max, and revenue goes to zero.
Or, they could just legislate basic 1800’s reliability measures.
Or, they could let all the idiots that voted these idiots freeze, but keep the industrial facilities online.
At this point, I don’t care. (Despite the efforts of some red state politicians to detain pregnant women, the US still has open internal borders, after all).
Anyway, I just want to be able to buy PVC the next time a line in my yard gets cut.
Nothing makes me give a shit about grid reliability in far off lands more than, well, a literal pool of it.
