As for the "no grid" comment - bullshit. Just because the weakest links, the interconnectors, failed to avoid the entire lot going down does not mean that the regional grids are not connected. Do you really think there is an air gap? What do you think? did you think before writing? Maybe read what you've written again and ponder the meaning of it and how it contradicts itself, then perhaps try again with increased understanding.
To dumb things down maybe you can pretend it's DC and consider Ohms law to get a bit of an idea about a badly designed grid and a badly designed interconnector 15 years ago can mean that you can't feed it as well from the area next door as well as you can today.
