Cold start is the grid's dirty secret — everyone assumes power comes back, almost nobody thinks about the fact that bringing a dead grid back up is one of the hardest coordination problems in engineering
No it's not. It's a pain in the ass but this isn't even close to correct. There are rocket launches and nanometer scale chips being built by engineers. Firing up some emergency diesel generators and syncing loads isn't easy, but don't be silly. I'm in charge of black start for a power grid. I've done it once and not looking forward to doing it again, but I'm not stressed out about it. And I'm not super smart.
