Powered by AMSC’s Amperium HTS wire, the 500m 80kV DC cable is installed in KEPCO’s electricity grid.
KEPCO president & CEO Hwan-Eik Cho said: "We believe Korea is the earliest country in the world to adopt smart and clean energy such as smart grid, Energy Storage System (ESS), and micro grid.
"The energizing of the first direct current high temperature superconductor cable in a real grid demonstrates KEPCO’s commitment to developing world-class, leading edge technologies.
"
"We expect to continue to develop superconductor cable projects with the objective of being the foremost utility in superconductor-enabled solutions."
The HVDC HTS cables are power dense and have zero resistance and can be used for moving large amounts of power underground and with a minimal footprint.
LS Cable & System president and CEO Ja-Eun Koo said: "The HVDC superconducting cable system offers transmission performance superior to that of the alternating current (AC) system."
AMSC president and CEO Daniel McGahn said: "With the energizing of the HVDC cable at Jeju Island, KEPCO and LS Cable have taken another step forward in upgrading Korea’s electricity network and fulfilling KEPCO’s vision of securing a world-class competitive edge through the development of green and smart technologies."
