Sounds like a good argument for de-centralization (Score 1)

I wonder if any of the "powers to be" have considred the possibility that organizing the national power grid into a set of isolated regional grids would be more fault tolerant.

In the IT server world, multiple servers (redundancy) is the key to uninterruptable service. Would it not stand to reason that we would want something so critical to our nation's welfare as our electricity to have a bit of redundant fault tolerance?

I suppose the paranoid, untrusting, conspiracy theorist in me would have something to say about this too...
