A critical part of Australia’s renewable energy future

Marinus Link is a proposed undersea and underground electricity and data interconnector between North West Tasmania and the Latrobe Valley in Victoria.

It will enable the flow of more electricity in both directions, delivering low-cost, reliable and clean energy for customers in the National Electricity Market (NEM).

With Marinus Link, Tasmania can import low-cost renewable energy, such as surplus solar, while reserving hydropower and storing the extra energy. Green hydropower can then be exported to the mainland grid when it is needed most to reduce the risk of brownouts.

BENEFITS

• Marinus Link will put downward pressure on electricity prices. It will provide more stable, abundant, low-cost and clean energy. This will result in lower wholesale energy prices than without Marinus Link. 
• Marinus Link will help Australia to meet its emissions reduction targets by saving up to 140 million tonnes of CO2 equivalent by 2050, equal to taking approximately 1 million cars off the road.
• Marinus Link will deliver 3300 direct and indirect jobs and about $3.9 billion in direct economic investment in Tasmania and Victoria.
• Marinus Link will support growth in business and industry, stimulating investment in Tasmania’s pumped hydro storage and wind generation, and clean, high-tech industries such as green hydrogen.
• Marinus Link will increase optic fibre capacity between Tasmania and Victoria, providing greater choice and reliability for customers, which will help keep prices low.
• Marinus Link will increase energy security. Customers on the NEM will have access to a more abundant and diverse renewable energy supply and storage.
