The attacks on transformers in North Carolina reveal a major danger

 

Karl Denninger points out that the attacks highlight our lack of preparedness to deal with such issues.

Two substations taken out with (presumed) small-arms rifle fire (e.g. bog-standard hunting rifles) from what obviously were a very small group of people, perhaps one or two at each location pissed off about who-knows-what.

Question: Why couldn't this be immediately fixed?

Answer: They don't have spares for the parts that were damaged.

. . .

Why do they not have the spares?

Because we sent our supply lines overseas, we made no provisions to have spares, and the regulators at the state and federal level sat on their hands and played with themselves instead of requiring that providers of critical services, such as electricity, had a sufficient stock of spares to cover both routine failures and those caused by weather or low-grade assaults perpetrated by small numbers of people.

This is the gross incompetence we have throughout our society.  It is the manifestation of "oh nothing bad will ever happen so we don't have to be prepared for it" that has shown up in all manner of other places, such as the cars that are completed except for chips in their engine computers without which they will not run, and thus they're sitting in a field unsold.

. . .

What you should learn from this is that this sort of disruption is tiny compared to what even one hundred dedicated men, uncorrelated and thus unable to be interdicted in advance could do any time they decided to.

Further, while I'm sure they'll find the parts somewhere in the US and restore power, if the damage was to fifty counties instead of one the odds are high that said parts would not exist at all in the United States and might not be available in sufficient quantity to actually restore service to everyone for months or even longer.

Speaking about the same issue, an anonymous commenter at Raconteur Report noted:

Just in case you all are not aware of the reality of our power grid and the companies that maintain them. Regional depots have maybe 1 or at most 2 of those larger HV transformers sitting in a warehouse, these are the ubiquitous monsters about 10x10 ft that convert the high tension down to more usable voltages for local distribution in our towns and factories. The smaller pole mounted units, perhaps in the few hundreds per depot, seeing they are a more common failure point due to heat, leaks, lighting strikes, trees falling or wayward ordnance.

What this means is that if there is ever a real effort to damage our grid by enemies, foreign or domestic, there is not enough replacement equipment on the ground in the entire country to fix it quickly.

Now the cute kicker or as they say, "and now the rest of the story". Most of our grid maintenance parts come from, yep, the PRC. And guess who will conveniently have "issues" in ramping up production for the export market, especially when they themselves are using most of the factory output internally (remember those 5 new coal plants going live/week over there)? Yes good sirs, we are royally screwed if any untoward events suddenly ramp up.

As a former Civil Defense sector officer, trained in disaster planning and recovery, allow me to assure you, that commenter is absolutely correct.  His words apply to every country on the planet.  The electrical utilities simply can't afford to stockpile large quantities of replacement transformers.  The bigger and more expensive the transformer, the fewer they'll have on hand.  Even simple components such as the glass insulators used on high-tension electrical cables criss-crossing the country are only stocked in limited quantities.  If random individuals were to pause alongside rural roads and shoot out, say, a thousand of those insulators, there'd be the devil to pay to replace them all in the short term.  If they shot out ten thousand . . . forget about it.  There aren't enough power crews, let alone insulators, to repair that sort of damage in anything less than weeks, possibly months.

If we don't make parts locally, we're dependent on outsiders to supply them - if they feel like doing so, and if they have the capacity to supply them in a hurry, and if the supply chain problems we're already experiencing allow them to get here fast enough to be useful.  And, if electrical utilities can't afford to stockpile enough of them, that needs to be funded as a priority by state and federal governments (not that any of our legislators appear to be aware of the need - they'd rather spend that money on entitlement programs and other areas that might garner votes for their re-election).

Food for thought . . .
