Some key insights from the article:
Basically, what they did was to look at how much batteries would be needed in a given area to provide constant power supply at least 97% of the time, and the calculate the costs of that solar+battery setup compared to coal and nuclear.
Vogtle’s numbers are incredibly biased considering they made an entire design and then had to redo it halfway through that’s not a realistic cost that can be expected for future projects. We also have vogtles design be approved now so that new plants can be built for a fraction of the cost. Also where did you see they did amortization of solar?
