Are they the fix? Is it really that simple? I don't know, just asking.
Its a good start. The last time I read a report on this issue the big problem was the supply of replacement transformers both at the local level and regional substations. Things may have changed in the last few years(doubt it) but there was no surplus of transformers. They were purchased as they were needed and there was only one company that supplied them.
Damage to the more complicated electrical infrastructure would still a friggin' mess but at least the electric co.s could get power going again if there were enough transformers staged across the country that could be plugged back in. This would at least help with water treatment, pumping, sewage, possibly gas stations and truck fueling( food transport etc.). Otherwise we're SOL.
