That is not what base load is. Base load is about some power plants that needs days to weeks to start and stop. They are unable to follow load changes. You build them anyway because they cost much less $$$ to run, but you need non-base load to handle varying power demands as your base load doesn't throttle very well.

While wind and solar do not meet the definition of base load, they clearly are in the spirit of base load.

When doing wind and solar you need non-base load, not more base load.
