> Seriously scaling nuclear would involve batteries. Nuclear has issues being cost effective at 80+% capacity factors.

I assume you mean that sub 80% capacity nuclear has issues being cost effective (which I agree is true).

You could pair the baseload nuclear with renewables during peak times and reduce battery dependency for scaling and maintaining higher utilization.

I meant even if you’re operating nuclear as baseload power looking forward the market rate for electricity looks rough without significant subsidies.

Daytime you’re facing solar head to head which is already dropping wholesale rates. Off peak is mostly users seeking cheap electricity so demand at 2AM is going to fall if power ends up cheaper at noon. Which means nuclear needs to make most of its money from the duck curve price peaks. But batteries are driving down peak prices.

Actually cheap nuclear would make this far easier, but there’s no obvious silver bullet.
