A clean energy highway strengthening Australia's national grid and promoting renewable energy investment.
DT Infrastructure (DTI) and Samsung C&T Corporation, through their joint venture TasVic Greenlink, have been engaged to carry-out significant infrastructure works for Stage 1 of the Marinus Link project.
Marinus Link is a nationally significant undersea and underground electricity and data interconnector project between Tasmania and Victoria. It will play a key role in Australia’s future National Electricity Market and in supporting emissions reductions targets by combining Victoria’s wind and solar with Tasmania’s flexible hydropower and geographically diverse wind.
At full capacity, Marinus Link will increase electricity transfer by 1500 MW and data capacity by 150 times. The project will promote new renewable energy investment and create thousands of jobs through construction, generating significant opportunities in North West Tasmania as well as Latrobe Valley, Gippsland and South Gippsland.
Scope
Stage 1 of the Marinus Link Balance of Works package includes the delivery of onshore civil works across multiple sites to support the installation of underground High Voltage Direct Current (HVDC) cables, the construction of two new converter stations in Tasmania and Victoria, and the delivery of a new communications building to support the project’s telecommunications and control systems.
Works include excavation, trenching, and site preparation to enable approximately 90 kilometres of underground HVDC land cable installation. Works will also include jointing, termination, and protection of existing assets in full compliance with technical and safety standards.
Throughout delivery, comprehensive environmental and safety management measures are being implemented to ensure compliance with all regulatory approvals, heritage, cultural heritage and ecological requirements, as well as workplace safety standards.
750MW

Social impact
During construction, the Marinus Link project will deliver significant social, economic and community benefits, including:
- The creation of up to 2,400 local jobs per year in Victoria and Tasmania.
- 750 MW capacity link providing low‑cost, reliable and clean energy for the National Electricity Market.
- Tailored programs for apprentices, trainees, cadets, and priority workforce groups, as well as initiatives to support women, youth, and underrepresented groups in the community.
- Partnerships with schools, training providers, and industry groups to create structured pathways, pre-apprenticeships, and transition programs that prepare the next generation of workers.
- Targeted employment and business opportunities, mentorship and scholarship programs, and culturally safe workplaces supported by cultural awareness training and engagement activities.
- Ongoing local engagement through workshops, supplier development programs, and social events to ensure regional communities share in the project’s benefits.
- Significant regional economic development through an emphasis on local procurement and investment.
- Comprehensive program of activities for ongoing consultation and engagement with local communities throughout construction.
- Commitment to sustainable construction practices to minimise environmental impact and support Australia’s renewable energy goals.
