There’s no “free market” for electricity anywhere in the developed world, including Texas. In the US, the grid is centrally planned by several regional transmission organizations. In Texas that’s ERCOT. An artificial market, a bid-auction system, is used to decide the actual price of electricity at any given moment. But in the case of ERCOT they concluded that, because outages prevent generators from making money during periods of peak demand, generators had adequate incentives to invest in reliability without a separate capacity market. And that worked fine for decades!

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.
