Prysmian and Marinus Link Pty have finalised a €600 m contract for a new power interconnector between Victoria and Tasmania, Australia. The commencement of the works is subject to the issuance of a notice to proceed, which is expected in or before August 2025. The agreement follows the prior announcement of a capacity reservation agreement dating from September 2023.

The project’s cables will stretch 345 km, 255 km of it undersea across Bass Strait and 90 km underground in Gippsland, Victoria, with the completion date set for 2030. With a capacity of 750 MW for the first stage, the Marinus Link will facilitate the flow of electricity and telecommunications between the two states, enabling transfer of power from the areas where renewable energy is generated to those where it is needed, and will help Australia meet its emissions reduction targets by saving up to 70 million tonnes of CO2 equivalent by 2050.

Prysmian will design, test, supply and install a high voltage direct current cable system, consisting of 320 kV single-core cables with XLPE insulation and single-wire armouring, covering both submarine and land sections. Prysmian will also provide a fully integrated PRY-CAM permanent monitoring system.

Submarine cables will be produced at Prysmian’s centre of excellence in Arco Felice, Italy, while the underground cables will be produced in Delft, The Netherlands, or Gron, France. Installation operations will be delivered with Prysmian’s cable-laying vessel, the Leonardo da Vinci.
