Singapore-based AI infrastructure company Firmus Technologies is planning to build three "AI factories" in northern Tasmania that would collectively require 400 megawatts of power — about two-fifths of the state's current electricity supply — a development that has cast doubt on the future of the multi-billion-dollar Marinus Link undersea cable project.

The Tasmanian government has revealed that Firmus, which is already building an AI factory at St Leonards near Launceston, intends to set up additional facilities at Bell Bay and Wesley Vale. The company has signed a contract with Aurora Energy for 104 megawatts to power the St Leonards site, which is expected to be operational early next year.

Coverage Comparison

Reporting from ABC Australia has highlighted the potential conflict between Firmus's power needs and the Marinus Link project, which would connect Tasmania to Victoria via a 255-kilometre undersea cable. Climate Change Authority chair Matt Kean told the Morgan Stanley Australia Summit in Sydney last week that the AI data centre proposals "bring into doubt the business case for the Marinus Link."

However, a separate report by independent economist Saul Eslake, commissioned by Clean Energy Tasmania, defends the project, arguing it will shore up Tasmania's energy security and break a "deadlock" that has hindered the state's energy sector development.

Key Claims

  • Firmus's power requirements: The three AI factories are estimated to require 400 megawatts of power, according to multiple reports. The St Leonards facility alone has secured 104 megawatts from Aurora.
  • Marinus Link business case: Matt Kean, chair of the Climate Change Authority, said the Firmus proposal and other data centre plans "bring into doubt" the business case for Marinus Link. This claim is reported by ABC and attributed to Kean's comments at an investment summit.
  • Marinus Link benefits: The project, estimated to cost $5 billion, would enable Tasmania to import low-cost renewable energy and export hydropower to the mainland, according to project proponents. Saul Eslake's report says it will create opportunity for both new demand and new supply.
  • Eslake's defense: Eslake argues that Marinus Link will give energy-intensive investors confidence in supply, helping to break the "catch-22" where Tasmania lacks both new generation and new demand.
  • Victorian Energy Policy Centre report: A report by the Victorian Energy Policy Centre has found that Marinus Link will impose "large and needless costs" on electricity consumers and taxpayers, according to a single source. This claim has not been independently verified.

Perspectives

Proponents of Marinus Link: Saul Eslake's report, prepared for Clean Energy Tasmania, argues the project is in the national and Tasmanian interest. He says it will provide a 750-megawatt cable between Tasmania and the National Electricity Market, with plans for a second cable, creating opportunities for both new energy generation and new industrial demand. Eslake criticizes the project's poor marketing by governments but maintains its necessity.

Skeptics of Marinus Link: Matt Kean's comments suggest that the rapid growth of AI data centres in Tasmania could make the interconnector redundant, as local power would be consumed by these facilities rather than exported. The Victorian Energy Policy Centre's report, though not detailed in the provided sources, apparently argues the project's costs outweigh its benefits.

Firmus Technologies: The company says it continues to assess potential sites in Tasmania, including George Town and Wesley Vale, guided by access to power, transmission connectivity, and planning pathways. It has not commented on the Marinus Link debate.

Context

Tasmania has not added new electricity generation since the Granville Harbour Wind Farm in 2020. The state's energy sector has faced a "deadlock" where lack of generation capacity discourages new industrial users, while lack of demand discourages new generation investment. Marinus Link is seen by supporters as a way to break this cycle, but the emergence of AI data centres as major power consumers could change the calculus.

Matt Kean's remarks at the Morgan Stanley summit reflect broader concerns about how rapidly evolving technology markets are outpacing government policy. He said, "Government policy needs to keep up with those rapid shifts if we're to realise the opportunity."

Firmus's plans extend beyond Tasmania, with the company also proposing facilities in Melbourne, Sydney, Perth, and Canberra, though these are at earlier stages.

As the Marinus Link business case is reviewed, the interplay between AI-driven power demand and traditional energy infrastructure will remain a key issue for Tasmania's energy future.
