Korea Energizes High Voltage Direct Current (HVDC) Superconductor Cable
Oct 29, 2014

DEVENS, Mass., Oct. 29, 2014 (GLOBE NEWSWIRE) -- Korea Electric Power Corporation (KEPCO), LS Cable & System, and AMSC (Nasdaq:AMSC), today announced that a high voltage direct current (HVDC) high temperature superconductor (HTS) cable has been energized on Jeju Island's smart grid demonstration site. The 500 meter, 80kV DC cable is powered by AMSC's Amperium® HTS wire and installed in KEPCO's electricity grid.

"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," said Hwan-Eik Cho, President & CEO, KEPCO. "We expect to continue to develop superconductor cable projects with the objective of being the foremost utility in superconductor-enabled solutions."

HVDC HTS cables are power dense and have zero resistance, making them an ideal solution to moving large amounts of power underground and with a minimal footprint. Capable of conducting 150 times the amount of electricity that can be conducted by copper or aluminum devices of the same size, HVDC HTS cables also benefit from no electrical losses, making them a perfect conductor of electricity. Designs exist for future cables that the Company anticipates will be capable of moving up to 10 gigawatts (GW) of power within an 8 meter right-of-way. A similar overhead circuit would require multiple extremely high voltage circuits and an approximately 120 meter right-of-way.

"The HVDC superconducting cable system offers transmission performance superior to that of the alternating current (AC) system. Interest in this technology has been building up in Asia, the United States and Europe, where new power network implementation is needed," said Ja-Eun Koo, President and CEO, LS Cable & System. "We remain focused on continuing to enhance our knowledge base and experience with superconductor cables so that we are well positioned to capitalize on opportunities around the world."

In 2011, KEPCO, LS Cable & System, and AMSC energized a 22.9 kV AC cable system at the I'cheon substation located near the city of Seoul. The cable successfully operated for two years. At the time of installation, it was the longest distribution voltage superconductor power cable in operation. KEPCO is also conducting type testing for a one kilometer, 154kV AC cable system that utilizes AMSC's Amperium HTS wire.

"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," said Daniel P. McGahn, President and CEO, AMSC.

Amperium wire is manufactured utilizing a proprietary process at AMSC's headquarters in Devens, Massachusetts - the world's largest commercial-scale HTS wire manufacturing facility. The wire can be used to increase efficiency and reduce the size and weight of a wide variety of applications, including power cables, motors, generators and defense systems.

This press release contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Any statements in this release regarding KEPCO's development of superconductor cable projects and its expectation of being the foremost utility in superconductor-enabled solutions; designs for and performance of future cables; the impact of the DC cable at Jeju Island on KEPCO's and LS Cable's competitive position; and other statements containing the words "believes," "anticipates," "plans," "expects," "will" and similar expressions, constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
