Neighborhood distribution lines are not long enough to be affected (much). The large, high-voltage transformers (greater than 110,000 volts) at either end of long grid runs will be the victims of solar flares. When they melt down, the extensive areas served by them with go without power until they are replaced. There are spares but not enough. It will take at least 6 months to get new 500kV/230kV transformers from China as they are not made here anymore. In the meantime, the spares, if needed, will be allocated to "priority" areas, such as DC, NY, LA, and so on. Everyone else will do without until the new units arrive and are installed.
I hate to disappoint you, but the high priority areas will all be in China, etc.
That is not a true statement. Large power transformers are still made in the US. Mexico is the significant competition in this market, not China.
