Preferred major works contractor earmarked for Marinus Link

Marinus Link Pty Ltd (MLPL), the organisation overseeing the planned electricity and data interconnector between Tasmania and Victoria, has named a preferred contractor for the project’s major civil works and construction tender.

The preferred bidder is TasVic Greenlink — a joint venture of DT Infrastructure and Samsung C&T Corporation. The ‘balance of works’ contract in question is the final of three major Marinus Link contracts, and the selection of TasVic Greenlink brings this significant renewable energy infrastructure project much closer to realisation.

The contract, currently in final negotiations with TasVic Greenlink, will cover the construction of converter stations in Heybridge and Hazelwood, the installation of equipment, and the land cable civil works, spanning 90 km across Gippsland.

Local businesses in Tasmania and Victoria are set to benefit from the recent announcement, with Marinus Link’s construction creating significant opportunities for sub-contractors and suppliers.

“The successful tenderer will need strong local business capability to deliver on this massive construction campaign, and we’ve set targets to incentivise this,” said MLPL CEO Stephanie McGregor. “TasVic Greenlink is keen to engage with potential subcontractors and suppliers during this next stage of the tender and into construction.

“In February, we invited local businesses to connect with our initial shortlisted bidders in Burnie, Morwell and Leongatha, and nearly 600 people turned up,” McGregor added.

“We’ve already passed on the details of over 500 subcontractors and suppliers who registered on the Industry Capability Network gateway previously.”

MLPL said the preferred bidder recommendation followed a robust and comprehensive evaluation process that considered capability, approach and overall value.

“With Marinus Link in place, Tasmania and Victoria will share much more electricity, pairing Victoria’s wind and solar with Tasmania’s flexible hydropower system and geographically diverse wind,” McGregor said. “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.”

Construction is expected to commence in 2026, subject to final environmental and regulatory approvals. Stage 1 is scheduled for completion by 2030.

“We’re continuing our engagement with landholders, local communities and businesses ahead of construction, and once our final key partner is signed on, we’ll be out and about at large,” McGregor said.
