Marinus Link reaffirmed as critical for Net Zero and grid reliability
Marinus Link welcomes the release today of the Australian Energy Market Operator’s (AEMO) 2025 Electricity Statement of Opportunities, which shows that major grid investments like Marinus Link are essential for the reliability and stability of the National Electricity Market.
The analysis follows AEMO’s “feedback loop” assessment, which found Marinus Link remains an optimal development on the lowest-cost pathway to Net Zero.
The two sets of evidence-based analyses by AEMO follow a major assessment in July, undertaken as part of the regulatory process, which found both market and consumer benefits remained strong.
“We welcome the continued scrutiny of this nationally significant infrastructure project through the independent regulatory process and today’s report by the national transmission planner,” Marinus Link CEO Stephanie McGregor said.
“Interconnectors, like Marinus Link, are absolutely essential pieces of infrastructure for reliability as ageing baseload generators retire and we move to a renewables-led grid backed by firming technology.”
“With Marinus Link in place, Tasmania and Victoria can share much more electricity, pairing Victoria’s wind and solar with Tasmania’s flexible hydropower system and geographically diverse wind. This is a powerful synergy that strengthens the grid for both states.”
“The project doesn’t just enable more electricity to flow – it also promotes investment in new clean energy projects and industry, in both Tasmania and Victoria.
AEMO’s feedback loop assessment considered the project’s latest refined costs, showing that Marinus Link continues to be a priority investment in the national electricity grid.
The project has made substantial progress this year, with a positive final investment decision and key Commonwealth and Victorian environmental approvals received.
“We’re mobilising to commence construction of Stage 1 next year to be completed by 2030 at a critical point in the grid’s transition to renewables.”
