No utility in the US has enough transformers on hand to replace them in the case that they all fail, hundreds of millions of transformers.

Even right now, disaster responses? All US mainland utilities are part of a emergency response pact (private, not government run) that obligates each other to send workers and equipment _at cost_ to each other. That's how things get fixed pretty quickly right now, they are depending on the supplies and labor of other utilities that weren't affected by the disaster.

That is far different than if the entire country is down.
