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. Marinus Link will be supported by transmission network developments on the North West Tasmanian electricity network.Show Less

Marinus Link involves approximately 250 kilometres of undersea High Voltage Direct Current (HVDC) cable and approximately 100 kilometres of underground HVDC cable. It will also include converter stations in Tasmania and Victoria, and approximately 220 kilometres of supporting High Voltage Alternating Current (HVAC) transmission network 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.

Marinus Link route

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

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.
