Yes, like the carrington event that caused some telegraphs stations to catch fire. Said telegraph lines were low voltage, 5-12v I believe. Trick is long distance power lines tend to have very high voltages, to save on the cost of copper. Said lines will be a boost from Geomagnetic storms, but not enough to noticeably change the voltage on a high voltage line.
