- Samsung C&T Engineering & Construction (E&C) Group has secured a KRW 470 billion share in Australia’s Marinus Link HVDC project, a 750 MW high-voltage direct current transmission system connecting Victoria and Tasmania through underground and subsea infrastructure
- The project award reflects strong technical evaluation during the Early Contractor Involvement phase, supported by Samsung C&T’s HVDC execution experience, and contributes to the company’s achievement of KRW 1 trillion in renewable energy orders in Australia this year
Samsung C&T E&C Group is accelerating its expansion in Australia’s energy infrastructure market after securing a major high-voltage direct current (HVDC) transmission project.
On December 10, Samsung C&T announced that it has signed a contract for the Marinus Link HVDC project, commissioned by Marinus Link Pty Ltd, a project company established by the Australian federal government and the state governments of Victoria and Tasmania.
Connecting Renewable Energy Across Regions
The Marinus Link HVDC project is a large-scale engineering, procurement, and construction (EPC) undertaking to design, procure, and construct a 750 MW ultra-high-voltage direct current transmission system linking the Hazelwood area in Victoria with the Heybridge area in Tasmania.
The project includes approximately 90 kilometers of underground transmission and 255 kilometers of subsea cable, forming a critical interconnector between Tasmania and mainland Australia. Once completed, it will enable stable, bidirectional power transmission while minimizing energy losses between Tasmania, which has abundant renewable energy resources, and Victoria and other mainland regions.
Samsung C&T is participating in the project through a joint venture with Australian infrastructure construction company DT Infrastructure (DTI). The joint venture has secured the civil works package covering underground cable installation and converter station construction. Of the total project value of approximately KRW 940 billion, Samsung C&T’s 50 percent share amounts to roughly KRW 470 billion.
Recognition of Technical Capability Through Early Involvement
Samsung C&T E&C received high evaluation scores during the Early Contractor Involvement (ECI) phase, in which contractors participate in design optimization from the early stages of project development.
The Group presented optimized design solutions and demonstrated execution capabilities built through prior HVDC projects, including its experience in the UAE. These strengths played a key role in securing the contract.
“The Marinus Link HVDC project represents a meaningful recognition of Samsung C&T’s technical capabilities and project execution expertise in the Australian market,” said Sung-jun Kim, Executive Vice President and Head of ES Sales at Samsung C&T. “We will continue to expand our business footprint across Australia and other global energy markets by building on our experience in large-scale energy infrastructure projects.”
Expanding Australia’s Renewable Energy Portfolio
Samsung C&T has steadily strengthened its presence in Australia’s renewable energy sector. In July, the company secured a KRW 200 billion battery energy storage system (BESS) project in Gnarwarre, Victoria.
With this latest HVDC contract, Samsung C&T has achieved KRW 1 trillion in renewable energy orders in Australia this year alone.
Since entering the Australian energy market with the Melbourne Renewable Energy Hub (MREH) project in 2023, Samsung C&T has been executing energy storage projects totaling 2.9 GWh.
The Marinus Link HVDC project further reinforces Samsung C&T’s position in Australia’s energy infrastructure sector while supporting the global transition toward a more resilient and interconnected renewable energy system.
