The US already used graphite bombs to disable 85% of the Iraqi electrical system in the 90s. Drones that autonomously target anything with insulator discs on it would make it rather cheaper, though.
It's still probably a war crime to target civilian infrastructure, however, so either win or deny using the drones and blame saboteurs now that the drones are cheap enough to reasonably suggest guerilla usage is possible.
