Sometimes, not very well if the twisted pair has a lot of splices or varies in impedance along it's route to your house.

Normally power lines can't carry high frequency signals because the power transformers won't pass them. The lines have some kind of bypass built into them at transformer points to allow the high frequency signal to pass on the line, no idea what kind of protocol voltages or frequencies are involved though.
