Funny enough yeah,you can trans mit data long range via powerlines.
I am old enough to remember the older career firefighters having devices at home that basically listened to the frequency shift.
If a certain signal was given (via the substations) that frequency shift was observed by the devices and an electric alarm bell was activated so people knew shit had hit the fan and they probably should head to work.
The power grid works on computronics tho, unless we use off grid solar or whatnot

It was already phased out,thought, back then.
That’s cool tech for sure, I didn’t know about that particular one
