Seoul – September 24, 2026 -- Hyosung Heavy Industries is scaling its proprietary voltage-source converter (VSC) HVDC technology to 2 gigawatts, building on a commercial base of 200 MW systems, as it targets a position among the world's top three power solutions providers within five years.
Hyosung began HVDC development in 2012 with a 20 MW demonstration project in Jeju
The company subsequently developed 200 MW converter valves and control systems and deployed them on live grids, building operational experience that it is now applying to large-scale 2 GW systems. Since 2012, Hyosung has pursued in-house development of core HVDC components rather than licensing external technology, part of a South Korean government push to localize converter valves, control systems and converter transformers.
