The bigger problem with solar and wind isn't baseline but rather the fact that they are variable in nature. That makes it harder to have a baseline power plant.

The reason natural gas is taking off is that it can quickly respond to differences in production vs demand (it's a peaker plant, as in it handles peaks in demand). Solar and wind make those peaks more pronounced while lowering what baseline can do.

This is why coal plants are dying, they are slow to respond to demand and renewables decrease the baseline that can run at (well, that and fuel costs keep rising due to inflation).

Storage solves both problems. Baseline can be higher, storage will consume it, and peaks are less a problem, storage can handle those.

Alternatively, load based demand would make sense (at least to solve the baseline problem). We could, for example, eat excess energy doing CO2 extraction (though, that only makes sense if baseline doesn't produce more co2 than what we are consuming).
