Yes, I searched after I opened my mouth ( insert foot ). However I still
maintain that most of the current operating long distance transmission
lines are HVAC. The articles I found listed a handful of HVDC lines, one
even originating in my home state of Utah. I learn new things every day.
Of course I forget them tomorrow so I can learn it again later, but that's
another story.
