Naples is hit too...lol.....boy does that grid jump the state!
It’s more complex than I can begin to understand, but each state is different with smaller subgrids of power lines making up the larger one.
When one gets knocked off, it causes the others to become unstable trying to compensate, and when it starts cascading to adjacent areas, it’s hard to stop.
You have to sever the connection or it’s like a virus that will spread. And it’s hard to get them all back up again. It require finesse at the power generating stations to bring them back up where they are synchronized. It’s way more complicated than simply turning an ignition switch on.
A lot of coordination is involved.
