KEPCO inaugurates new test-site for HVDC transmission lines

South Korean power utility, Korea Electric Power Corporation (KEPCO), has opened a site for testing the world’s highest-voltage direct current (HVDC) transmission lines.

These lines will be used in large-scale offshore wind power projects. Moreover, the facility will serve as an outpost for cable manufacturers to enter the global cable market, as it is suitable for easy and quick demonstration of cables under development.The test site can carry out experiments on the operation, performance and specifications of ±800 kV HVDC lines, with up to two HVDC cables/lines tested simultaneously.In addition to helping prepare Korea’s power system for the future, enhancing domestic cable manufacturers’ international competitiveness, and contributing to 2050 carbon neutrality, the HVDC cable demonstration test site will contribute to the expansion of renewable energy in Korea.
