Hyosung Scales HVDC Tech to 2 GW, Targets Top-3 Grid Rank in 5 Years

Seoul – September 25, 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.

Seoul – September 10, 2026 -- Hyosung Heavy Industries has developed the world's first 22.9kV, 1.05MVA-class Solid State Transformer (SST) capable of direct connection to urban distribution networks, giving the South Korean manufacturer an early lead in a market projected to grow more than 40% annually.

AI-driven power demand pushes Hyosung to scale U.S. production

The company has invested USD 300 million to acquire and expand an ultra-high-voltage transformer manufacturing facility in Memphis, Tennessee, which will become one of the largest such production bases in the United States once expansion completes.
