“One big advantage to HVDC is the efficiency of power transmission over long distances,” George Culbertson, vice president of power delivery markets for HDR, told POWER. “If the transmission line route is longer than about 300 miles, DC is a better option because AC lines have more line losses than DC for bulk power transfer.”I had to look this up. Of course that would prevent stealing power with induction coils placed beneath the transmission lines too I guess.
The really strange part is that I am told only one leg of the power circuit goes over the lines.
The other is the pacific ocean.
