Well, I suppose. People say that multiple failures are unlikely, but I've seen plenty of times where you get a whole bunch of anomalies all at once, throughout the system, that combine to bollux things up. Granted, I'm in the space business, but the network aspects are essentially the same.
And, given that there's probably a higher-than-normal load in the system right now, I'm betting it wouldn't take much to cause a cascade of problems throughout the grid.
If, OTOH, MrClark's correct about MSNBC reporting oil explosions in NJ.... Well, that's a different thing entirely.
Granted, higher loads take you closer to the edge, but I've been in the business for 20 years. Utilities aren't all following the rules any more, and they aren't building in adequate transmission or generation reserves any more. Its too expensive in a competitive market to be the one with the adequate contingency capability. Plus, hyper-nimbyism has created some areas that just cannot withstand any contingencies at all. New York may be such an area.
