> and that nuclear makes great baseline power generation.

While it is true nuclear power is great for baseload power generation. Sadly, that is a nice way of saying this form of power production sucks at load following.

Which is a problem in grids with sufficient solar and/or wind doesn't need baseload power production. It require complimentary power supply/production.

Sufficient, meaning enough VRE to there being enough variable production that there at times the full power production of the nuclear power plant isn't required.
