Prysmian Marinus Link Project Strengthens TasmaniaโVictoria Power Connection
Prysmian Groupย has agreed toย reserve capacity for the Marinus Link project, a major power interconnector that will connect Tasmania and Victoria, Australia. The projectโs client,ย Marinus Link Pty Ltd., operates as a subsidiary of the Australian transmission system operatorย TasNetworks.
Theย Prysmian Marinus Link projectย will strengthen energy reliability across Australiaโs electricity market, providing a key infrastructure link that supports renewable generation across both states.
Capacity Reservation and Project Scope
Prysmian has reserved production and installation capacity for the design, testing, and delivery of a high-voltage direct current (HVDC) cable system rated at 320 kV. The system includes single-core cables withย XLPE insulationย and single-wire armoring for both submarine and land applications.
The complete submarine section will run approximately 255 km from northwest Tasmania to Waratah Bay, Victoria. The underground section will extend about 90 km, reaching the Latrobe Valley in Victoria. The link will also include a 255 km submarine fiber optic cable to support real-time communication and monitoring.
The project contract, valued at around โฌ90 million, is expected to be finalized by the end of 2024.
Advanced Manufacturing and Technology Integration
Prysmian Group plans to produce the submarine cables at itsย Arco Feliceย plant in Italy. The company will manufacture the land cables at either itsย Delftย facility in the Netherlands or itsย Grondย plant in France. Cable installation will be carried out using Prysmianโs advanced cable-laying vessel, theย Leonardo da Vinci.
As part of theย Prysmian Marinus Link project, the company will also install itsย PRY-CAM permanent monitoring system. This technology provides continuous distributed temperature sensing (DTS) and acoustic sensing (DAS) to track all essential performance data, ensuring reliable and safe cable operations.
Strengthening Prysmian Groupโs Global Leadership
โThis capacity reservation agreement carries strategic importance for Prysmian,โ saidย Detlev Waimann, Chief Commercial Officer of Projects BU for Prysmian Group. โIt highlights our continued global leadership and reinforces our presence in Oceania as a trusted supplier of high-tech cable systems to power utilities.โ
Supporting Australiaโs Evolving Energy Landscape
Initially, theย Marinus Link projectย called for two 750-megawatt cables estimated at $3 billion in 2017. However, rising raw material costs and inflation increased total projections to $5.4 billion. The revised design will move forward with a single cable, valued between $1.9 and $2 billion. This version will still deliver approximately two-thirds of the original projectโs power capacityโan efficient and cost-optimized solution for Australiaโs evolving energy needs.
