This is true of gas turbines and coal at this point too, though.

We clearly need something to stabilize power output, and nuclear is extremely competitive with solar+wind+battery for weeklong storms/weather patterns that lead to low power output and high demand.

Those storms happen about once a year. The only sustainable options on the table are massive energy storage projects, or nuclear.

I’m all for putting batteries on the grid, but they typically only smooth out 4-8 hours of load, not the 4-8 days most places need once a year.
