Which might be right! But are the externalities all correctly priced in here?
It’s not a choice of “free market versus regulation.” It’s a heavily regulated market. The question is only about the design of the regulatory scheme.
I'm reminded of Enron's "grandma Millie" comments.

The only partisan bickering is the attempt to incorrectly blame renewables for the lack of capacity when in fact planned downtime, ordinary logistical failures, and failure to winterize are in fact to blame.
Everybody ought to have expected them to need that much power. Not every day and not every winter but everyone ought to have expected another bad winter to come round because they had bad winters in 1957 1960 1973 1985 2015 2017 2021. This includes 3 years out of the last 6.
They weren't prepared because they were short sighted, greedy, and stupid not because solar took so much of the profits and not because insufficient capacity had been built out for lack of such profits. Capacity existed and it sat unused or broke when it was most needed.
Renewable power throws a wrench in how Texas does grid planning. In every other ISO, there is both a capacity market, which pays providers to commit to making certain generating capacity available, and a generation market, which pays for actual electrical production: https://cpowerenergymanagement.com/why-doesnt-texas-have-a-c.... In Texas, there is just a generation market.
Ordinarily that isn’t a big deal. Generators build adequate capacity so they can be in a position to receive payments for generation at times of peak demand.
Renewables break this down. They undercut traditional generation sources in the summer, but can’t be counted on to be there at times of peak winter demand. So last winter renewables didn’t fail in the sense that nobody was expecting them to generate much power begin with. But the natural gas plants that are irreplaceable for dealing with winter demand are dealing with reduced revenue because renewable sources are underbidding them in peak summer months.
