DC power transmission is now state of the art, and was pioneered by the Europeans to allow transfer of large amounts of current between countries without having to synchronize the separate alternating current systems.

One recent system using DC is a 660 megawatt DC cable(s) that runs 65 miles from Sayerville, New Jersey, to Hicksville New York on Long Island, underwater and across the mouth of New York Harbor. Converter stations at each end convert the local power grid to and from AC.

Here's a WiKi article link about high voltage DC:
