well. . .by looking at the map and the probable location (near niagara falls), you can note that convergence of several high voltage lines just into canada. . .if one of those tripped, the casacade would fall to both sides, thus, down to nyc and to the other side, cleveland and ohio. while the entire u.s. grid is interconnected (except texas), pjm should have enough power itself to buffer it's grid from the failure, which it did. however, with this new report about ohio being the cause, i haven't a clue how this entire transmission grid failed. . .i know why the power plants shut down, but why the lines failed. . .guess i'll have to wait a few years for ferc to finally issue its report.
btw, i do this for a living too.
