The ugly truth is; that after 6 months of no power, power will never be restored. The Chaos, the lack of food and clean water, the rioting and general Anarchy, the rampant disease and deaths, will disperse the qualified personnel and destroy or otherwise stop the replacement equipment from arriving, so that the project of restoration can never be finished. After Katrina, the street gangs were said to have attacked police and rescue teams and cleanup personnel, as they preferred the chaos. It allowed them to operate freely without government control. This would create a similar result, but on a National scale. These types of things are not considered or planned for, by the people who say it might take a year to fix, they would be right under normal circumstances but not under these circumstances.
