I realize this isn't relevant for a discussion about future investment, but the current "value" of the whole energy infrastructure for a state is probably in the hundreds of billions of dollars, right? It's been built out over decades, of course, so the actual costs per year are much lower.
That's definitely possible. Going based upon the output of something like Catawba, that looks like ~3 nuclear plants. I bet that could be done for less than 100B, though I'd just be guessing. I also don't know anything about operations costs for that.
Also, I estimated solar at $1.5/watt. That's probably at least 50% too high.
