Why It Matters
Starting with the 20MW voltage-type HVDC demonstration project in Jeju in 2012, Hyosung Heavy Industries has continued to localize and demonstrate core technologies, including developing 200MW major facilities such as converter valves and control systems and applying them to the actual power grid.
Hyosung Heavy Industries announced on the 17th that it participated in the '2026 Korea Energy Expo' held at BEXCO in Busan until the 18th and unveiled key HVDC facilities such as valves and controllers selected for the ultra-high voltage direct current transmission (HVDC) localization demonstration project.
The converter valve developed by Hyosung Heavy Industries with its own technology uses power semiconductors to convert power between alternating current (AC) and direct current (DC). The controller controls the size and direction of power and protects the power grid in the event of a system abnormality. Both are considered key equipment for stable operation of large-capacity HVDC systems.
On the 10th, Hyosung Heavy Industries was finally selected as a participating company in the valve and controller field of the 'Large Capacity Voltage HVDC Localization and Demonstration Project' promoted by Korea Electric Power Corporation.
The government and KEPCO have been promoting the local production of core technologies to secure a stable supply chain in the high-capacity voltage-type HVDC equipment market, which is dominated by a few global companies.
Starting with the 20MW (megawatt) voltage-type HVDC demonstration project in Jeju in 2012, Hyosung Heavy Industries has continued to localize and demonstrate core technologies, including developing 200MW-class major facilities such as converter valves and control systems and applying them to actual power grids.
Open Questions
- When will the HVDC facility be commercialized?
- What is the expected cost reduction effect if localization is successful?
- What HVDC components will be subject to additional localization in the future?
