Data centre firm challenges generator restrictions in Tasmania appeal

We need to slow things down and really have a good look
A Rowella resident opposing the data centre expresses concern about the pace of industrial development in rural Tasmania.

So Firmus got approval from the council, but now they're saying the conditions are too strict. What exactly are they asking for?

Mimi

They want to use the diesel generators beyond just emergencies and maintenance. Right now the rules say generators can only run during power failures, genuine emergencies, or testing between 8am and 6pm on weekdays. Firmus wants to use them when the grid is stressed or curtailed—basically to supplement power when demand is high.

Luke

But we don't actually know how often they'd use them, right? Firmus wouldn't say when asked.

Mimi

Correct. They declined to comment on anticipated usage frequency.

Mark

And the community is fighting back?

Mimi

Absolutely. Residents like Nicholla Thompson are appealing the approval itself. They're worried about noise, light pollution, air quality, and the impact on local tourism and vineyards.

Luke

How many people are we talking about in the appeals?

Mimi

Thompson filed with five other Rowella residents. She mentioned at least three other appeals on the TASCAT website, but the exact number of people involved isn't clear from public records—appeals are only visible to interested parties.

Mark

What's the bigger picture here?

Mimi

Firmus is planning three data centres across Tasmania. If Hydro Tasmania approves their full power request, it would be 450 megawatts—up to 30 per cent of the state's current energy use.

Luke

And Hydro Tasmania hasn't decided yet?

Mimi

No, they're expected to decide by year's end. So this generator appeal is just one piece of a much larger conversation about how much power the state can or should allocate to data centres.

Mark

What happens next?

Mimi

The tribunal will hear both sides. The outcome could set the tone for future data centre approvals in Tasmania.

  • 288-megawatt data centre approved by George Town Council in August 2026
  • Condition 13 restricts generator use to emergencies and 8am-6pm weekday maintenance only
  • Firmus seeks to use generators during electricity curtailment and energy market stress
  • Community petition against the facility gathered over 6,000 signatures
  • Firmus' three planned facilities would require 450 megawatts—up to 30% of Tasmania's current energy use

The George Town Council approved a massive AI data centre but imposed strict conditions limiting diesel generator use to emergencies and maintenance between 8am-6pm weekdays only. Firmus now argues these restrictions are unreasonable and prevent operational efficiency, seeking permission to use generators during electricity curtailment and energy market stress.

Firmus Technologies has appealed conditions on its approved 288-megawatt data centre in Tasmania, seeking to use diesel generators beyond strict backup-only limits to augment power supply during energy stress.

Firmus Technologies, an artificial intelligence data centre company, has taken its fight with Tasmania's regulators to the tribunal. In August, the George Town Council approved the company's 288-megawatt facility at Bell Bay, 15 kilometres south of the town, making Firmus the state's largest single power consumer. But the approval came with strings attached—fifteen conditions designed to limit the facility's environmental footprint and operational impact on the surrounding community. Now, less than a month after that vote, Firmus is asking the Tasmanian Civil and Administrative Tribunal to loosen one of the most restrictive of those conditions: the rules governing when and how its diesel generators can run.

Condition 13, as written by the council, is unambiguous. The backup generators may operate only during genuine emergencies, unscheduled power failures, or scheduled maintenance and testing. That testing window is narrow: 8am to 6pm, Monday through Friday, excluding public holidays. The generators cannot be used to supplement the main electricity grid during normal operations, and simultaneous testing of more than one generator is capped at 24 hours per calendar year. Firmus argues this framework is unreasonable. In its appeal, the company contends that the restriction prevents it from using the generators during periods of electricity curtailment, network constraints, or energy market stress—situations where, Firmus claims, the backup power could maintain operational efficiency and grid reliability. The company declined to specify how frequently it expects to deploy the generators beyond these approved scenarios.

The approval process itself was contentious. An online petition against the data centre gathered more than 6,000 signatures. Dozens of residents gathered outside the council chambers before the vote, which passed 6–1 in favour of the project. That opposition has not quieted. Nicholla Thompson, a Rowella resident who moved to the rural riverside community six years ago seeking a quieter life, was among the protesters. She and five neighbours, including Anne-Marie Bastian, have filed their own appeal to TASCAT challenging the council's decision. Their concerns centre on light and noise pollution, degradation of quality of life, and potential damage to the local tourism industry, which includes several wedding venues and award-winning vineyards across the river from the proposed site. Thompson said she was "flabbergasted" to learn of Firmus' appeal when she filed hers. "We need to slow things down and really have a good look before we just start slapping [data centres] up anywhere," she said.

The generator dispute sits within a much larger energy question facing Tasmania. Hydro Tasmania, the state's electricity supplier, is reviewing Firmus' request for 450 megawatts of power across three facilities—equivalent to up to 30 per cent of the state's current energy consumption. The company is pursuing an aggressive expansion: the Bell Bay centre is approved, a 104-megawatt facility outside Launceston is under construction, and a development application has been submitted for a 52-megawatt centre in Wesley Vale, east of Devonport. Hydro Tasmania expects to make a decision on the power allocation by year's end. Before Firmus can begin construction at Bell Bay, it must also submit an updated bushfire and emergency management plan. The company initially reported 276 diesel generators on site but later revised that figure to 128—a discrepancy that triggered the requirement for a new safety assessment.

The appeals process is now underway, with multiple parties contesting the council's decision. Thompson noted that at least three other appeals were listed on the TASCAT website alongside hers and Firmus', though appeals are only visible to interested parties. The tribunal will weigh the company's operational needs against community concerns about pollution, environmental impact, and the pace of industrial development in rural Tasmania. The outcome will shape not only this facility but the precedent for how the state manages the energy demands of data centre expansion.

Condition 13 is unreasonable because it restricts the operation of the approved backup diesel generators in a manner that fails to adequately recognise both the operational requirements of the facility and the benefits of their limited use during periods of electricity supply curtailment, network constraints or energy market stress.
