Overview

• Marinus Link issued notices to proceed to Prysmian Powerlink and Hitachi Energy, enabling final engineering and pre‑construction to start.
• Stage 1 will deliver 750 MW as part of a 1.5 GW, 345‑kilometre interconnector with 255 kilometres undersea linking north‑west Tasmania to Victoria’s Latrobe Valley.
• Construction mobilisation is planned for 2026 with completion of Stage 1 targeted for 2030.
• The CEFC’s concessional loan covers about 80% of Stage 1’s estimated $5 billion cost, alongside equity from the Commonwealth (~49%), Victoria (~33%) and Tasmania (~17%).
• Project proponents cite a 45% reduction in transmission‑related bill impacts, about $900 million in consumer benefits over the first five years and estimated annual household savings of $25–$36, with costs recovered through regulated network charges and a regulator’s final cost determination still pending.
