I think the often cited problem is that if a national electricity grid goes down, its a very long and complex job to get them back up again, especially if transformers are damaged.

If there's no damage, it doesn't take that long. We had a blackout in 2009 in which the national grid of two countries (Itaipu is shared between Brazil and Paraguay) went down; I'm looking at the official report right now, and it took less than half a day to restore nearly all of the system for this country. Of course, if there's damage beyond the redundancies, it can take much longer; see for instance the recent blackout in the Amapá state, in which two transformers at a key substation were damaged by fire (and the third was under maintenance).

  2003 had a large blackout across the US and Canada, looks like it took 4 days to restore power everywhere: https://en.wikipedia.org/wiki/Northeast_blackout_of_2003 https://en.wikipedia.org/wiki/Northeast_blackout_of_2003
