• Tasmania has six confidential data-centre proposals that could require at least 500MW if all are developed
  • Two have reached feasibility assessment, while four remain concepts and none has been presented as approved electricity demand

The fact

Six more data-centre proposals are being explored in Tasmania, according to a state government document reported on 9 September after being tabled in parliament the previous day. ABC reported that two proposals have reached feasibility assessment and include preferred sites, while the other four remain at concept stage. If all six proceed, they could require at least 500MW of power. The proponents have not been named, and the government has not said whether six separate companies are involved.

The disclosure follows draft state expectations released on 7 September. The government wants new data centres to support additional renewable generation, contribute fairly to network and connection costs, and use water responsibly. Consultation remains open until 12 October. In addition, they also said projects will not receive automatic approval or special treatment. None of the six proposals has been presented as having secured approvals, electricity supply or construction funding.

The assessment

The six projects should not be treated as a single 500MW block of future demand. Two already have preferred sites, while four are still concepts. Those stages carry very different implications for utilities and energy developers deciding how much prospective data-centre demand to include in their own plans.

Tasmania's draft expectations add another step before that demand becomes more certain. Developers may be expected to support new renewable supply and pay an appropriate share of network costs, which means their power requirements will need to become clearer as projects advance. A preferred site, a demand schedule and an electricity arrangement would say far more about likely load than the combined headline figure.

For BTW readers, the useful signal will be individual projects moving beyond preliminary discussions. A proposal that secures approvals and ties its planned load to an electricity arrangement gives energy and network planners something firmer to work with. Until then, the 500MW figure describes a possible pipeline rather than electricity demand that Tasmania must already supply.

What to watch

Watch for any of the six proposals to move into approvals and disclose a site, power requirement and electricity arrangement. The final state expectations after consultation closes on 12 October should also clarify what developers must provide for additional generation and network costs.
