Another good article on the subject from IEEE 2 years ago with good sidebar
articles and video:
"Of all the parts of the power grid, high-voltage transformers are among the
most likely to fail in a geomagnetic storm and also among the most difficult to
replace. If a big storm were to knock out several hundred transformers in one
fell swoop, manufacturers wouldn't be able to supply replacements quickly-there
is no global stockpile. EHV transformers, which can handle voltages of 345 kV
or higher, weigh about 200 tons and cost about $10 million each. Building one
requires exquisite, near-artisanal craftsmanship, including meticulously hand
winding the paper-tape insulation around the copper winding at the
transformer's core. One EHV transformer can take several weeks to assemble and
test, and it takes years to train skilled assemblers. Even the largest
transformer plants can build only about 30 to 50 per year. With the shortage of
skilled labor and specialized materials that would likely accompany a prolonged
blackout, simply maintaining that level of output would be a cha
llenge, never mind ramping up new production."

The radio outage will be the least of our problems after a big one.

Whether it's major or minor, there is a massive CME on the way. The
article is written for the general public, but worth reading:
