Why not?

Some studies have even predicted that interference
problems

What's causing the interference?

According to http://www.arrl.org/news/stories/2003/08/08/2/?nc=1 , BRL is
using frequecies of 2 - 80 MHz (i.e. HF and sneaking into the bottom end
of
VHF). I suspect that the power cables are acting as antenna.

The lines are pretty "long" at those frequencies, to make much of an
antenna.
