Marinus Link Pty Ltd (MLPL) has reached financial close for its proposed Marinus Link power transmission project in Australia, and issued notices to proceed for its cable and converter contracts. The Australian Government’s Clean Energy Finance Corporation (CEFC) has committed up to AUD3.8bn (US$2.7bn) to support the project.
The Marinus Link is a proposed 1.5 GW electricity interconnector, consisting of a 255-kilometre subsea cable running from Burnie in north-west Tasmania to Waratah Bay in Victoria, followed by a 90-kilometre underground section to the Latrobe Valley. MLPL, a joint venture owned by the Commonwealth of Australia, the State of Tasmania, and the State of Victoria, is responsible for delivering the project, which will be built in two 750 MW stages. The interconnector will enable two-way electricity exchange between Tasmania and mainland Australia, facilitating the integration of Tasmania’s hydropower and wind resources with surplus solar and wind generation from Victoria and New South Wales.
In 2024, MLPL signed contracts with Hitachi Energy for the supply of converter stations and with Prysmian Powerlink for the high-voltage direct current (HVDC) cables. In August 2025, the Australian, Tasmanian, and Victorian governments made a final investment decision on the project’s first stage. Construction is expected to begin in 2026, with completion scheduled for 2030.
