The information below provides an overview of the current contract status for Marinus Link.
Hitachi Energy
In May 2024, Hitachi Energy was contracted to supply its HVDC LightR voltage source converter stations for Marinus Link Stage 1. These will convert alternating current (AC) to direct current (DC) for efficient, long-distance transmission and DC to AC, where the electricity is returned to the grid. The advanced converter technology will also help to stabilise the grid and enable the integration of more renewable energy. Hitachi Energy pioneered commercial HVDC technology 70 years ago and has delivered more than half of the world's HVDC projects. Today, the company has the largest installed base of HVDC in the world.

Prysmian Powerlink
In August 2024, Prysmian Powerlink was contracted to design, manufacture, supply and install the project's HVDC and fibre optic cables for Stage 1. Prysmian is an Italian company and the world's largest cable manufacturer. The project's cables span 345 kilometres (km). This includes 255 km of undersea cables across Bass Strait and 90 km of underground cables in Gippsland, Victoria. Marinus Link's HVDC submarine cables will be manufactured at Prysmian's Arco Felice factory in Naples and laid by the Leonardo Da Vinci - Prysmian's most advanced cabling vessel. The land cables will be manufactured in a different factory in Gron, France.

TasVic Greenlink
In September 2025, MLPL selected TasVic Greenlink (TVGL) as the preferred bidder in the project's major civils and construction tender. TVGL is a joint venture of DT Infrastructure and Samsung C&T Corporation.
The 'balance of works' contract is the final of three major contracts, and the selection of the preferred bidder marks a significant next step towards constructing this landmark renewable energy infrastructure project.
The contract, currently in final negotiations with TasVic Greenlink, will cover the construction of converter stations in Heybridge and Hazelwood, the installation of equipment and the land cable civil works, which spans 90km across Gippsland.

About the project
Marinus Link is a proposed undersea and underground electricity and data interconnector between North West Tasmania and the Latrobe Valley in Victoria. It includes high voltage direct current (HVDC) cables, fibre optic cables, a communications station, and converter stations at each end. The project's cables span 345 kilometres (km). This includes 255 km of undersea cables across Bass Strait and 90 km of underground cables in Gippsland, Victoria.
The project will enable Tasmania and Victoria to share more electricity, pairing Victoria's wind and solar with Tasmania's flexible hydropower system and geographically diverse wind. This is a powerful synergy that strengthens the grid for both states.
Marinus Link also promotes investment in new clean energy projects and industry, in both Tasmania and Victoria.
Marinus Link Pty Ltd is jointly owned by the Commonwealth of Australia, the State of Tasmania and the State of Victoria.
Marinus Link will be supported by 240 kilometres of new and upgraded overhead transmission lines and other energy infrastructure in Tasmania, called the North West Transmission Developments.
