This process of islanding, or decoupling one’s local grid from the system as a whole, is not easy given the current organization and size of our interconnections. And though it was a wise protective measure (in 2003 islanding kept a great many power plants and power lines in New York State from being destroyed by massive swings in voltage), it also caused the blackout in that state.
