The source of the interference must be relatively close, physically, to the cable, in order for the cable to pick up sufficient noise to interfere with signals. A power plant, or even a Tesla coil, in the building next door will have zero effect on your cables' signal integrity.
your LAN cable, it's attached to power cabling that runs all over the place.Of course, having said that, that doesn't necessarily make a case for shielded cable. Induced currents in poorly wired power-line grounding probably effect you more if you're using shielded
