DC has lower line losses over long distances. Voltage conversion on DC adds losses but the net result for long high voltage DC transmission is greater efficiency.


Supposedly the skin effect causes some losses even at 50/60Hz. In Tesla and Edison's time the DC voltages were very low compared to AC which caused the efficiency difference. Modern power electronics make 1+ MV DC possible.
