"How many substations would it take to shutdown electrical generation in the US?"

Taking out substations doesn't directly take out any generators. The big problem is that when the grid goes down, there can be no place to put the power. A nuclear plant has about 20 seconds to fire up diesel generators to run cooling pumps and to shut the plant down once it looses the grid. If not, it will overheat. That said, local plants can generate locally, grid or no grid. The grid balances power, it doesn't generate it. There certainly could be major disruptions. There are still enough ingenious people in this country that most wouldn't sit around and die, just because someone shot insulators off nine electrical substations.

The recent attack damaged 17 transformers (that had to be taken out of service) at one substation. That's hardly shooting some insulators.

How many substations will it take for people to start dying?
