Yep its the big power transformers on the electricity grids that would be at risk from a major CME because they are grounded and its the high ground currents from major CMEs that can overload transformers and cause them to fail. The coils inside can even melt, not an quick thing to fix!
Quoting: Anonymous Coward 7546576 thanks for sharing this very useful info unfortunately their info is incorrect prepare as you will There is a 197 page report called "Geomagnetic Storms and Their Impacts on the U.S. Power Grid", do a search for it on Google. It concludes that 100's to 1,000's of transformers in the US grid alone are at risk of failing in a worst case CME scenario. I agree that the transformers are at risk do you know why? poor grounding that would cause gound potential to raise now, one has to ask, with the power grid poorly grounded, what will cause the charge to disapate as it would need to go to ground if a 50 volt charge spike came over your neutral/ground in the house, that is now 170V which will kill any electronic product designed for 120 the voltage spikes from a serious event will easily exceed an extra 50 volts
