Not trying to be a "nuclear shill", but it is worth mentioning from the article you linked:
The 1.8 million solar panels are expected to generate up to 690 MW and they’re co-located with 380 MW of 4-hour battery energy storage (1,400 MWh).
The capacity factor of solar is something around 25%, so that 690 MW solar array (even with batteries) produces about as much energy as ~160 MW nuclear... So 7x faster, but the costs are closer than you suggest. Solar is still cheaper because the O&M costs are minimal, but pretending 690 MW solar + 380 MW battery is equivalent to 1 GW nuclear is a bit disingenuous.
Naïve/entitled people fail to grasp the concept of compromise.
