With a rated power of 1400MW, the Kii Channel HVDC system in Japan is, as of 2012, the highest-capacity high-voltage direct current (HVDC) submarine power cable system in the world to use a single bipole. The cross channel system between England and France has a larger total capacity, but uses two bipoles rated at 1000MW each.
The Kii Channel HVDC system connects the Anan static inverter plant, located south of Tachibana Power Plant, at 33°49′40″N 134°38′14″E / 33.82778°N 134.63722°E on the Japanese Home Island of Shikoku, with the inverter plant at Kihoku ( coordinates: 34°12′50″N 135°30′07″E / 34.21389°N 135.50194°E) on the largest of the Home Islands, Honshu.
