Cutting costs on the cold-proofing of wind turbines in Texas is somewhat understandable. But as far as under-investment due to lack of profit goes, nuclear isn't much better off.

The economics of building a traditional nuclear plant right now don't work out: they are incredibly expensive to build and tear down, take a decade to plan and another decade to build. In the time until a new nuclear plant is built and has paid back the investment you could have built a wind park, made back the investment, made a profit, decommissioned it, built a new one and made back the investment for that one.

Maybe small-scale nuclear will help somewhat, but properly weather proofed wind and gas would work just fine too.
