It doesn't have to be space-based to be affected. If the ionosphere gets active due to the impact of charged particles from a CME, it can affect transmission towers. That's why previous noteworthy storms have knocked out power grids, which aren't space-based either.

Did you not see my reference to cellular service?

The effect whereby High Voltage Transformers as used in HV transmisison systems see *do* DC Current on their windings (THEREBY saturating their iron cores to one side or the other of the BH curve) as induced on long lines between substations *is* well documented.
