Pivoting to cost of renewables
Solid planning estimate is $1/watt installed.
It's actually kinda hard to pin down a good number here, the renewable world is moving fast. Offshore wind is a bit pricier but dropping fast, onshore wind and solar are in that range, and the powers that be are now openly musing on over the horizon possibility of ultra low cost electricity driven by solar installs at $0.3 (30 cents!) a watt installed.
Let's run with $1/watt.
So matching the faceplate capacity of our reference nuclear plant is $1B.
Renewables have intermittency to deal with, and in the case of solar that pesky nighttime daytime thing, so we'll need to spend more to genuinely match.
The go to combination option is more generating capacity plus a battery. Let's run those numbers.
