Marinus Link is a proposed 1500 megawatt capacity undersea and underground electricity connection to further link Tasmania and Victoria as part of Australia’s future electricity grid. It is supported by over 230km of transmission developments in North West Tasmania. Collectively, these projects are known as Project Marinus.  

Marinus Link involves approximately 255 kilometres of undersea High Voltage Direct Current (HVDC) cable and approximately 100 kilometres of underground HVDC cable in Victoria. It also includes converter stations in Tasmania and Victoria, and approximately 230 kilometres of supporting High Voltage Alternating Current (HVAC) transmission developments in North West Tasmania.

Together, Marinus Link and the supporting transmission developments will unlock Tasmania’s renewable energy and storage resources to deliver low-cost, reliable and clean energy for customers in the National Electricity Market. In addition, Marinus Link will help cut at least 140 million tonnes of CO2-equivalent by 2050. This is the equivalent of removing more than a million combustion engine cars from our roads.

Marinus Link route

The proposed route for Marinus Link will run from North West Tasmania to the Latrobe Valley in Victoria.

Marinus Link will not follow the same route as Basslink in Tasmania or Victoria. This geographic diversity will support a more reliable and secure electricity supply for customers.

The proposed location of Marinus Link in North West Tasmania enables connection into some of Australia’s best renewable energy and storage resources. In Victoria, the proposed connection is at Hazelwood Substation where there is access to significant Latrobe Valley transmission capacity.

Interconnectors

The project is an interconnector, as it connect two or more transmission networks. Interconnectors allow power to flow between different regions (i.e., between Tasmania to Victoria), and allow the efficient transfer of electricity from renewable energy generation zones to where the electricity is needed.  Interconnectors can increase the resilience of the National Electricity Market (NEM) and make energy more secure, affordable and sustainable for customers.

Interconnectors are common around the world including in Australia. They play a critical role in supporting Australia’s transition to a clean energy future.
