Samsung C&T’s construction division is accelerating its expansion into Australia’s energy market after securing a major high-voltage direct current (HVDC) transmission project.
On December 18, Samsung C&T announced that it has signed a contract for the Marinus Link HVDC project, commissioned by Marinus Link Pty Ltd, a company jointly established by the Australian federal government and the governments of Victoria and Tasmania.
The project involves the engineering, procurement, and construction (EPC) of a 750-megawatt HVDC transmission system connecting the Hazelwood area in Victoria with the Heybridge area in Tasmania. The transmission route spans approximately 345 kilometers, including 90 kilometers of underground cable and 255 kilometers of subsea cable.
Once completed, the Marinus Link HVDC system will enable stable, bidirectional power transmission between Tasmania—home to abundant renewable energy resources—and mainland Australia, while minimizing energy losses. The project is expected to play a key role in strengthening Australia’s power grid and supporting the country’s energy transition.
Samsung C&T formed a joint venture with local infrastructure specialist DT Infrastructure to secure the civil works and converter station construction package for the underground cable installation. Of the total project value of approximately KRW 940 billion, Samsung C&T holds a 50% stake, amounting to about KRW 470 billion.
The company received high marks from the project owner by presenting optimized design solutions during the early contractor involvement (ECI) phase and by leveraging its proven execution capabilities from previous HVDC projects in the United Arab Emirates.
Kim Sung-joon, Vice President and Head of the ES Business Development Division at Samsung C&T, said the Marinus Link HVDC contract demonstrates the company’s technical expertise and project execution capabilities in the Australian market. He added that Samsung C&T will continue to expand its footprint in Australia and the global energy sector.
Samsung C&T has been steadily strengthening its presence in Australia’s energy market. In July, the company won the Gnarwarre battery energy storage system (BESS) project in Victoria, valued at approximately KRW 200 billion, bringing its total order intake in Australia’s energy sector this year to more than KRW 1 trillion. Since entering the Australian market with the Melbourne Renewable Energy Hub project in 2023, Samsung C&T has been delivering energy storage projects totaling 2.9 GWh. With the Marinus Link HVDC project, Samsung C&T aims to solidify its position as a key player in Australia’s energy infrastructure and lead the global energy transition.
