The company said Wednesday it held a review meeting at its headquarters in Seoul’s Mapo district with officials from Korea Electric Power Corp., the Korea Electrical Manufacturers Association, and experts from industry, academia and research institutes.
The West Coast Energy Superhighway is a national backbone grid project aimed at reliably delivering large-scale offshore wind power to the Seoul metropolitan area. The meeting was set up to closely assess progress in localizing large-capacity, voltage-source HVDC technology — an area that has relied heavily on overseas technology — and to discuss next steps.
Hyosung Heavy Industries presented the status of its localization work on key components for a 2-gigawatt voltage-source HVDC system, including converter valves and control systems. The company said voltage-source HVDC makes power control easier than conventional current-source systems and is advantageous for grid stability, making it essential for connecting renewable energy.
Presentations also were given by leading domestic experts. Professors from Seoul National University, Yonsei University and Kyungpook National University, participating as a technical cooperation group, discussed research in areas including system optimization and grid-stabilization technologies. Lee Jong-pil, a center director at the Korea Electrotechnology Research Institute who joined as an adviser, presented on certification testing for converter valves, a core component.
Participants agreed the West Coast Energy Superhighway could serve not only as a domestic grid buildout but also as a springboard for Korean HVDC technology to enter global markets. They said technology self-reliance could lead to a broader domestic HVDC ecosystem spanning equipment, systems and engineering, and strengthen export competitiveness.
“HVDC technology is at the core of national energy security,” Seoul National University professor Choi Seong-hwi said. “To reduce dependence on overseas technology and secure sovereignty over the power grid, building a localization ecosystem is essential.”
A Hyosung Heavy Industries official said the company is moving ahead with localization “without disruption” based on capabilities built up in power equipment and HVDC technology. The official said Hyosung plans to complete the project successfully through close cooperation with related organizations, including the government and KEPCO, and to expand into global markets.
