Could be a test like you say.I'm guessing you're probably familiar with the Metcalf substation attack in San Jose a few years ago
In your opinion how dangerous would that be if carried out simultaneously on maybe 4 or 5 regional major routing substations?
It seems to me at least that it would cause a massive regional cascading failure that would take perhaps weeks to restore.
The individuals who pulled off the Metcalf substation attack demonstrated a significant amount of operational planning and discipline. No reason to think they wouldn't be capable of doing the same thing replicated on a larger scale. (I think there is a chance it was an Iranian sleeper cell beta test)
I wouldn't really call it that sophisticated though, maybe well coordinated is all.
If it was sophisticated it could have probably done a lot more damage.
Shooting up a transformer with an AK doesn't strike me as that sophisticated, especially when it didn't even fail until it leaked out enough oil to overheat.
Certainly a coordinated attack on multiple sites could be devastating. It wouldn't take that many people either, they could drive from site to site, it's unlikely they could all be secured quickly.
