Tasmania's Secret AI Load: 500 MW, No Names, No Water

A tabled paper lists 10 AI centres and up to 1,150 MW of interest — but the six biggest newcomers have no names, mostly no sites, and no water figures.

Tasmania says it wants to be transparent about its AI boom, and then tables a document that names no names. Six proposed data centres appear only as numbers — proponents three to eight — with most sites undisclosed, owners undisclosed, and every water figure left blank.⁠12⁠15 What is disclosed is the load: two of the ghost projects could each draw up to 300 megawatts on an island grid that peaked at 1,770 megawatts last year.⁠12⁠68 That is the contradiction at the heart of this story — a public grid asked to carry a private surge it is not allowed to see.

up to 1,150 MWPotential demand, ten-centre pipeline 12

The paper was tabled on September 9 in response to a Greens transparency motion that passed the lower house on September 2.⁠12⁠14 It counts ten AI data centres in the pipeline with up to roughly 1,150 megawatts of potential demand.⁠12⁠15 That figure is pipeline interest, not committed or connected load, a distinction the government itself stresses.⁠12 After three named Firmus Technologies projects and a small Viridis project at Burnie comes the confidential tail: six early-stage proposals the government would not attribute to one company or several.⁠12⁠15 Firmus has confirmed it is not behind the six.⁠12

The six break down unevenly, and the staging matters. One feasibility-stage project is on hold, needing more than 1 megawatt, with no disclosed location.⁠12 One feasibility-stage project has a preferred site in the northwest and could use up to 300 megawatts.⁠12 One concept-stage project has no identified site and could also use up to 300 megawatts.⁠12 Three more concept-stage projects have no sites and each require 5 to 50 megawatts.⁠12 Combined, the range is roughly 505 to 705 megawatts, reported as at least 500 megawatts.⁠12 Two are at feasibility stage, meaning a site has been selected, while four remain concepts.⁠12 One concrete lead slipped out: a 50-megawatt concept-stage project has expressed interest in the closed Bell Bay manganese smelter in northern Tasmania.⁠12

Water left blank

Water is where the document is thinnest. For all six confidential proposals, water use is listed as “not defined.”⁠12⁠15 That stands in sharp contrast to the named projects sitting beside them in the same table: Firmus’s Bell Bay site was given an annual figure of 8,700 kilolitres and its Wesley Vale site 448 kilolitres.⁠12 The omission is not explained project by project. The government said detail was withheld on commercial sensitivity grounds, or because information was “not yet available, not sufficiently settled, not capable of reliable estimation or has been provided to the Office of the Coordinator-General in confidence.”⁠12⁠15 That office shepherded proponents, helped some identify sites and made introductions to energy and utility providers.⁠12

The government is actively keeping Tasmanians in the dark.

Greens leader Rosalie Woodruff said the government had been working behind closed doors with developers for months, if not years.⁠13 Premier Jeremy Rockliff rejected what he called a scare campaign, said Tasmanians reasonably want more information, and argued data centres are the kind of investment the state should attract.⁠12 Energy Minister Nick Duigan restated the government rule that new load must bring new generation.⁠12 On September 7 the government released non-binding draft “Expectations for Data Centres and AI Infrastructure,” with Minister for Business, Industry and Resources Felix Ellis saying no project receives automatic approval or special treatment.⁠65⁠66 The Greens branded the framework “an absolute joke,” and Independent MP Helen Burnet joined calls for a moratorium.⁠67⁠56

A grid with little slack

The stakes are physical, not theoretical. A single 300-megawatt facility would be roughly 17 percent of the state’s system peak, about the scale of the Bell Bay aluminium smelter often cited around 335 megawatts.⁠12⁠68 Tasmania’s firm capacity is constrained. Hydro Tasmania holds about 2,290 megawatts across 30 stations but output depends on inflows and storages, wind adds roughly 560 to 570 megawatts of variable power, the Tamar Valley gas plant of about 372 megawatts is a dry-year backup, and Basslink can import around 478 megawatts.⁠76⁠68 Through 2025, drought forced the state to fire up its biggest gas plant for the first time in five years.⁠73 New large load without matching new renewable generation pushes directly at prices and at power security — the two things the draft framework says it aims to protect.⁠65⁠66

The pressure for disclosure came from petition politics. Greens MP Cecily Rosol tabled a petition on September 2 calling for a moratorium on AI data centres until community and environmental safeguards are in place.⁠53⁠38 The Greens say it carried 10,035 signatures, while the parliament’s own e-petitions page records 7,204, filed by Launceston principal petitioner Jamie Andrew Melvin between June 22 and August 10.⁠53⁠54 The gap between the two counts is itself unresolved, but either total makes it one of the largest e-petitions in Tasmanian parliamentary history.⁠53⁠39

The only near-term decision is not about the six at all. Hydro Tasmania is to decide by the end of the year on Firmus Technologies’ separate request for 450 megawatts across its three proposed sites.⁠22 Those are St Leonards under construction, a 288-megawatt Bell Bay project approved on August 25 by a 6-1 George Town council vote, and a mooted 52-megawatt Wesley Vale project filed September 2.⁠47⁠48⁠22 The six confidential projects are earlier and looser; several have not yet engaged energy generators or TasNetworks, so their timing and even their fate are unknown.⁠12

যা জানা গেছে

  • Six confidential AI proposals would add roughly 505 to 705 MW if all proceeded. 12
  • Water use for all six is listed as not defined, unlike named Firmus figures. 12
  • Tasmania’s 2024-25 system peak was 1,770 MW. 68

যা অজানা

  • No names, exact sites beyond one northwest preference and one Bell Bay smelter interest, or timelines for the six.
  • Correct moratorium petition total and what Tasmania gains in jobs or revenue.

এরপর

  • Hydro Tasmania’s end-of-year ruling on Firmus’s 450 MW request and whether any confidential load must fund new generation.
  • Whether parliament’s inquiry turns draft expectations into binding guardrails before sites lock in.

  1. Two secret AI data centres could each draw 300 megawatts — 17 percent of Tasmania's peak.
  2. The six proposals together could add more than 500 megawatts to a grid already pushed to its limits by drought. The companies behind them are unnamed, their sites mostly unknown, and not one lists a water requirement. So the question is simple: who is behind these proposals, and what does Tasmania actually get back?
  3. The disclosure came in a government document tabled in parliament on September ninth, produced after a Greens transparency motion passed the lower house on September second. The document counts ten AI data centres in the pipeline, with up to roughly eleven fifty megawatts of potential demand — a figure the government calls pipeline interest, not committed load. Six of those are new and confidential. The document lists them as proponents three to eight, after three named Firmus projects and a small Viridis project in Burnie. The government would not say whether they are one company or several.
  4. Of the six, one is on hold, needing just over a megawatt, with no disclosed location. Two are feasibility-stage — one with a preferred site in the northwest, one concept-stage with no site — and both could draw up to three hundred megawatts. The other three are concept-stage, each needing five to fifty megawatts. Combined, though, the six could demand roughly five hundred and five to seven hundred and five megawatts — reported as at least five hundred.
  5. And here's where the secrecy is sharpest: for all six proposals, water use is listed as "not defined." That stands in sharp contrast to the named projects beside them in the same table.
  6. Firmus Technologies is named, with three sites and water figures listed. The six confidential proposals are the opposite: no names, mostly no sites, and for every one of them, water is simply marked "not defined."
  7. The government withheld detail on the grounds of commercial sensitivity, or said some information was "not yet available, not sufficiently settled, not capable of reliable estimation or has been provided to the Office of the Coordinator-General in confidence." That office shepherded proponents, helped some identify sites, and made introductions to energy and utility providers. The Greens argue the confidentiality protects the proponents, not the Tasmanians who will carry the network, water and price costs.
  8. The document itself shows the gap: water is not defined for the confidential six, while Firmus's Bell Bay site carries an annual figure of 8,700 kilolitres and its Wesley Vale site 448 kilolitres.
  9. Now the grid context. Tasmania's peak demand in the 2024-25 year was 1,770 megawatts. A single 300 megawatt facility would be roughly 17 percent of that — about the scale of the Bell Bay aluminium smelter, often cited around 335 megawatts.
  10. Tasmania's firm capacity is constrained. Hydro Tasmania holds about 2,290 megawatts across 30 stations, but output depends on inflows and storages. Wind adds roughly 560 to 570 megawatts of variable power. The Tamar Valley gas plant, about 372 megawatts, is the dry-year backup. And Basslink can import around 478 megawatts. Through 2025, drought forced the state to fire up its largest gas plant for the first time in five years. New large load without matching new renewable generation pushes directly at prices and at power security — the two things the government's own draft framework says it aims to protect.
  11. The conflict over the secrecy became the story's sharpest turn. The government argues the tabled document itself is the transparency, but the Greens see it differently.
  12. Premier Jeremy Rockliff rejected a "scare campaign," said Tasmanians reasonably want more information, and argued data centres are the kind of investment the state should attract. Energy Minister Nick Duigan restated that new load must bring new generation. And on September seventh, the government released non-binding draft "Expectations for Data Centres and AI Infrastructure." Minister Felix Ellis said no project receives automatic approval or special treatment. The Greens branded the framework "an absolute joke." Independent MP Helen Burnet joined the moratorium calls. The moratorium petition itself carries a counting conflict: the Greens say 10,035 signatures, while the parliament's e-petitions page records 7,204, filed by Launceston principal petitioner Jamie Andrew Melvin between June 22 and August 10.
  13. Meanwhile, the most concrete decision is still pending. Hydro Tasmania is to decide by the end of this year on Firmus Technologies' separate request for 450 megawatts across its three proposed sites: St Leonards under construction, a 288-megawatt Bell Bay project approved by George Town Council six-to-one on August twenty-fifth, and a mooted 52-megawatt Wesley Vale project filed September second. Firmus has confirmed it is not behind the six confidential proposals.
  14. Those six are earlier and looser. Several have not yet engaged energy generators or TasNetworks, so their timing and even their fate are unknown. The Greens' ongoing parliamentary inquiry, and the moratorium petition, frame the question hanging over the state: whether Tasmania's renewable surplus will be sold at scale to undisclosed multinationals, behind commercial confidentiality, before any binding guardrail is in place.
