Marinus Link secures green light for major electricity interconnector
The Marinus Link project, a proposed 750 MW high voltage direct current (HVDC) electricity interconnector, has received the official go-ahead to commence Stage 1 construction. The project, designed to strengthen the connection between Tasmania and Victoria on the National Electricity Market, has reached its Stage 1 financial investment decision, marking a significant milestone for Australia’s energy infrastructure.
Stage 1 construction to boost energy security and renewables integration
With the financial green light secured, Marinus Link will move directly into its initial construction phase. The interconnector is expected to enhance energy security, improve grid reliability, and facilitate greater integration of renewable energy resources across both states. By linking Tasmania’s hydropower and Victoria’s renewables, Marinus Link will help balance supply, support emissions reduction targets, and enable more flexible electricity trading.
Major infrastructure investment for regional growth and jobs
The project represents a substantial investment in regional infrastructure, with construction set to create hundreds of jobs in both Tasmania and Victoria. Local communities are expected to benefit from increased economic activity and long-term opportunities as the project progresses.
Driving Australia’s clean energy transition
Sector analysts highlight Marinus Link as a key enabler of Australia’s clean energy transition, providing critical transmission capacity to unlock new renewable projects and support national decarbonisation goals. The interconnector is also expected to boost resilience in the National Electricity Market by allowing more efficient sharing of resources between states.
Looking ahead: Timelines and future stages
With Stage 1 construction now underway, project leaders will continue to engage with stakeholders and progress planning for subsequent phases. The successful delivery of Marinus Link is set to play a pivotal role in shaping Australia’s future energy landscape.
