Might help if an ice storm hit part of the state and destroyed those types of lines. I watched a line of electric towers fall during the big ice storm. Made a bizarre green glow as the whole line collapsed. They had to evacuate Montréal because they lost two of the three major supply lines going to it. Everyone there has electric heat. No power, everyone freezes.

But yea, generally it's the local circuits. One part gets cut, they all go out. Like old fashioned Christmas lights.
