The weak link in our electric grid are power transformers, because these are large, essential, long operational life equipment, whose inventory grew slowly over a century of electrification efforts. So if a large number of them blows at the same time, it takes the grid down and we don't have enough spares or production capacity to replace them timely.

Amapa state in Brazil got a taste of such disaster scenario, when the local electricity company was privatizated and management decided to eliminate redundancy and cut costs on maintenance to increase profit margins. The main transformer catched fire and no replacement or backup were available and the region endured weeks without power. See https://www.aljazeera.com/opinions/2020/12/18/the-crisis-in-...

Wow. That's exactly the sort of busted-bottleneck situation I was worried about during Covid. I'm used to hurricanes knocking out water and/or power for a few days, but a month is insane. There's no way a normal person with a normal amount of money and space can "prep" to live off-grid for a month. Part of the social contract is that you trade taxes in return for not having to worry about this kind of shit.
