There was no blackout in my country past 30 years. The last one was before the revolution, that was before we had enough nuclear.
It's a shock that they have been investing incredible amounts of money into it for decades and still couldn't match the few nuclear reactors they turned off, indeed. At least they have the social/political argument - they turned the nukes off because they didn't like it. It's dumb but respectable. Lying about it being cheaper than nuclear is not respectable.
