It's usually not that simple. Not all power sources are equal. Solar and wind, which Spain is focusing on, are very variable unlike geothermal and hydro for example. Nuclear and gas are very attractive for grid stability. Inter-connectors with other countries also help. Renewable + storage is going to get very exciting going forward, assuming we get battery storage less prone to fires.

Nuclear isn’t a great option for grid stability - you can’t easily vary it like gas or pumped or biomass.

Why would you need to vary free energy?

Nuclear isn’t free

If you can’t support peak load with nuclear you have to have variable load like gas or bio or pumped

Once the factory is running, what are the marginal savings if you reduce the number of kW produced?

You can have nuclear for the base load and anything else for the peak load, and it would be better than not having nuclear for the base load.

How does that help stability? You still need the peakers, unless you propose building excess amounts at massive capital cost to be used for an hour or two a day

I meant you don't need to vary nuclear plants down when they're producing too much electricity, I guess that does mean you'd need to be over capacity as a matter of course.

What do you do with the excess power?
