How is it immaterial to build twice as many nuclear power plants as necessary instead of using energy storage? You'd have to believe battery storage is way more expensive than an idle nuclear plant. But that's just not the case. The real killer in that comparison is that people really don't want to live near a nuclear plant and in any case, regulation and such politics makes it hard or impossible to scale up nuclear power in that way.
