Cascading power failures can eventually spread out of state unless wise operators cut the transmission lines.
It sounds like Florida is in the midst of that right now.
It would be better for all of Florida to go dark than to allow it to spread throughout the entire eastern grid.
Naples is hit too...lol.....boy does that grid jump the state!
Fla. never lost their ties to the rest of the interconnection. There were some swings on the system but no problems.
