It’s not just base load, turbines also provide grid stability. All the quick fluctuations as people turn things on and off are hard to load balance with solar, wind, or battery.
A big spinning turbine has a lot of inertia. That helps keep thr grid at a constant frequency. As solar gets bigger and bigger we might need big solar powdered flywheel generators just to stabilize the grid.
Inverters could also provide “virtual inertia” which help to stabilize the grid frequency. However most of today’s inverters don’t have it, or it’s disabled.
This means we don’t need solar powered flywheels, which are inherently inefficient, we just need software (edit: and batteries of course) more or less.
Partially. Inverters providing virtual inertia is good but has the problem of still being active and reactive. It helps and is cheaper and more efficient than flywheels.
Flywheels and turbines however provide a very sticky frequency. They help out a lot with stability and give inverters time to respond.
Think balancing a stick on your hand vs anchoring it in clay.
If we take enough turbines off line we are still probably going to need some mechanical power stabilization no matter how inefficient.
But yeah I think we are going to see a blend using as much electrical and as little mechanical as possible.

Lol,
Batteries are perfect for load balancing.
Please, know your facts
Batteries can’t stabilise frequency. If the frequency changes too much, the grid will go down.
You literally need a giant spinning turbine for this.
It’s pretty basic energy engineering, and is not related to load balancing.
