Any simulation where building nuclear power plants makes economic sense would do.
> I'm unconvinced that renewables+storage alone can solve the Minnesota winter problem.
You're again asking for simulations about Minnesota specifically which doesn't make sense. Unless you're thinking of seceding from the union and closing the borders to energy trade, as long as the US as a whole can do it Minnesota in particular can be a net energy importer in winter if that's what's needed. Here's the RethinkX simulation of that:

"Our analysis makes severely constraining assumptions, and by extrapolating our results from California, Texas, and New England to the entire country we find that the continental United States as a whole could achieve 100% clean electricity from solar PV, onshore wind power, and lithium-ion batteries by 2030 for a capital investment of less than $2 trillion, with an average system electricity cost nationwide of under 3 cents per kilowatt-hour if 50% or more of the system’s super power is utilized."
This is almost 5 years old at this point. Others have linked other such analysis. At this point asking people to show them simulations for renewables while trying to argue for nuclear is disingenuous. Renewables are the ones being built out at scale all over the world while nuclear struggles to deliver new projects and doesn't seem to have a viable path to being cheap.
