Development plans and electricity supply
Plans are being pursued to build an AI data center campus on the site of a large cattle feedlot near Dalby in Queensland, Australia. The development cost is about A$31.9 billion, and the maximum power requirement reported in the media is 2.16GW. For the region, this is both an opportunity to attract a new industry and jobs and a major development requiring scrutiny of how much electricity and water it will use and who will bear the burden. The project is called Western Downs Digital Park. Singapore-based developer Zerra DC is pursuing the project on a site in Kogan, about 37km northwest of Dalby. The site covers 725.5 hectares, or about 7.26 square kilometers, and is about 250km from Brisbane.
An agreement has also been announced for US AI company Anthropic to become the tenant of the first-phase facility. However, signing a lease and securing approval, financing and completion of construction for the entire project are different stages. The developer also explicitly states that the project is currently subject to planning and regulatory approvals. At the exchange rate of 934.19 won per Australian dollar published by Investing.com on October 2, 2026, A$31.9 billion is approximately 29.8 trillion won. This amount describes the scale of the overall development plan; it does not mean that this much money has already been spent.
According to plans described by specialist publication Data Center Dynamics, the project site is an existing cattle feedlot. Nearby electricity infrastructure includes the Braemar substation, gas-fired power plants and solar farms. Proximity to urban consumers and businesses is not the only consideration when locating a data center. Access to a reliable, large-scale electricity supply and sufficient land also matters. The Western Downs project proposes locating a major new electricity-consuming facility in an established energy industry region.
However, proximity to power plants and a substation does not mean all the required electricity has been secured. Electricity generated by nearby facilities is already supplied to other customers and the electricity market. The arrival of a new consumer requires a combined review of generation, transmission capacity, supply contracts and grid operating conditions. The developer's phased plans include data centers, substations and battery-based power management facilities. This means the project involves not just constructing buildings but also establishing electricity infrastructure and operating arrangements. The region's accumulated experience in building energy facilities is an asset, but it does not replace grid connection approval.
The most prominent figure in coverage of the project is 2.16GW. On September 14, 2026, Australian public broadcaster ABC described this as the maximum power requirement when the project is fully developed. However, directly describing it as exactly 25% of Queensland's current peak demand leaves the basis of comparison unclear. The Queensland government's 2025 Energy Roadmap gives the peak demand recorded on January 22, 2025, as 11,144MW. A simple comparison of the reported project scale of 2,160MW with that figure gives about 19.4%. Against this official record, it is approximately one-fifth.
By contrast, the estimated daily electricity use reported by ABC is about 47GWh, compared with Queensland's average daily consumption of about 170GWh. Dividing the former by the latter gives about 27.6%. The description of roughly one-quarter of the state's consumption can be understood in the context of this comparison of daily energy use.
GW measures power used at a particular moment, while GWh measures electrical energy consumed over a period of time. Maximum power, average daily consumption and actual annual consumption are not interchangeable. Even with a large design capacity, actual consumption varies according to the phased commissioning of buildings and the extent of server installation. Furthermore, 2.16GW is not a measured operating result from a facility already in service. It is the scale of the plan currently being reported. Until the final connection capacity and operating load are established, this figure alone cannot support firm conclusions about electricity prices or carbon emissions.
A disclosure dated September 16, 2026, from real estate and infrastructure investment company Dexus provides evidence of the project's progress. Dexus said Australian Data Centres (ADC), in which it holds an 85% stake, owns 25% of the project consortium formed with Zerra DC and Macquarie Capital. According to the disclosure, the consortium signed lease-related documents with Anthropic's Australian subsidiary to provide the first-phase facility. The agreement is subject to conditions including the necessary approvals. Macquarie Capital is also the consortium's financial adviser.
The same disclosure also shows that financing is being pursued separately. ADC is undertaking a capital raising to attract additional investors, and Dexus said it had not decided at that time whether to participate. Funding commitments for both the first and subsequent phases were also subject to conditions including board approval. The involvement of a major tenant is an important development supporting demand for the project. However, it cannot be interpreted as meaning that financing for the entire campus is complete or that construction of every phase is confirmed. In particular, for a development divided into several phases, the contract for the first building must be distinguished from the scale envisaged at final completion.
The developer's information states that the project will bear the costs of the required grid connection and associated network upgrades. Plans have also been presented for Anthropic to pursue long-term power purchase agreements for new wind, solar and storage facilities. These are all key matters to examine in assessing how burdens on existing users would be reduced. However, the developer's payment of connection construction costs does not eliminate every effect on the electricity market. Market effects depend on how much additional generation is ready when electricity is needed and which facilities respond during supply shortages. Connection costs, electricity procurement costs and the balance of supply and demand at different times must be distinguished.
In material on responding to data centers released on June 1, 2026, the Australian Energy Market Operator (AEMO) identified efficient grid connections, improved demand forecasting, and rules and standards to maintain power system security as key tasks. It also explained that data center growth is rapid, concentrated in particular regions and difficult to predict. This means electricity use by major consumers cannot be managed solely as annual totals. Aligning generation and transmission plans requires knowing where and when facilities will begin operating and how quickly their loads will change. It matters whether the schedules of planned electricity-consuming facilities and electricity supply facilities remain aligned.
At the current stage, neither claims that the project will lower electricity prices nor claims that it will inevitably raise them can be treated as established outcomes. Its effects can be assessed only once new generation investments, supply contracts and connection conditions become more concrete.
In AI data centers, changes in server workloads translate into changes in electricity demand. The International Energy Agency's (IEA) 2026 report, Key Questions on Energy and AI, explains that AI training and use can cause large, rapid power fluctuations, making energy storage systems important for reliable supply. The Western Downs project's battery-based power management facilities can also be understood in this context. Managing short-duration load fluctuations and power quality can help major electricity-consuming facilities operate reliably. However, the specific effects depend on equipment capacity, control methods and grid connection conditions.
Batteries are not a source of electricity generation. They supply previously charged electricity at another time, so their presence alone does not mean nighttime supply needs or prolonged generation shortages have been resolved. The power output they can sustain and for how long must also be specified. The same applies to renewable energy contracts. Contracts that support new generation are meaningful, but matching annual purchases and supplying the electricity needed every hour are different tasks. The project's actual energy characteristics will become apparent not just through contract announcements but through supply and storage at different times and arrangements for covering shortfalls.
Water use and cooling
On water, the figures in early reporting must be distinguished from the developer's current explanation. In the current model published by the developer, total operational water use for the first data center building is about 21 cubic meters per day. The plan is to recycle about 8 cubic meters on site and supply the remaining approximately 13 cubic meters mainly from rainwater. These figures apply to the first building, not the entire campus. The developer explicitly states that water demand will increase as subsequent phases proceed and that estimates may change during detailed design and approval processes. Presenting the first building's water use as that of the entire project would misrepresent its scale.
The cooling method must also be understood accurately. The developer says it will not use cooling that rejects heat through water evaporation. Internal closed-loop circulation must be distinguished from the method used to release heat outside, and the term air-cooled does not mean there is no water in any pipework or operating process. The IEA's 2025 Energy and AI report explains that data centers operate not only servers but also auxiliary equipment for cooling, environmental control and uninterruptible power supplies. The share of electricity consumed by cooling equipment also varies widely with facility type and efficiency. Whether a design reduces water use and how efficiently it uses electricity overall must be checked separately.
The developer's description of low water use reflects design targets and modeling results. It is not yet an operating record. Actual verification will need to examine whether planned cooling performance and water use are maintained under conditions such as high outdoor temperatures and maximum server loads.
Construction creates separate water demand. Based on early application documents, ABC reported on August 24, 2026, that construction water use would be about 522 cubic meters per day. It also reported that one-time flushing and filling would require about 26,900 cubic meters per building. These figures concern different periods and purposes from the current operational water estimates. They should not all be added together as though they represent consumption during the same period. Conversely, construction demand should not be omitted simply because operational water use is described as low. Civil works, equipment commissioning and normal operations each require their own supply plans.
The developer has proposed sourcing construction water mainly from treated water produced by nearby coal seam gas operations, subject to contracts and approvals. For operations, it says it does not plan to connect to the municipal water supply and intends to use rainwater and reused water.
There are also reasons for the region's sensitivity to water issues. According to the Western Downs Regional Council's information on Dalby's water supply upgrade, the area has historically depended on groundwater from the Condamine Alluvium because the reliability of surface water supplies is limited. The council is pursuing long-term water infrastructure upgrades in response to population and economic growth. Residents therefore want to understand more than annual average use. Their concerns include storage and alternative sources during prolonged droughts, concentrated construction demand and the effects of transporting water. Water supply upgrades for existing residents and the data center's independent water plans must also be distinguished as separate projects.
Employment, community benefits and approvals
The developer expects about 1,400 direct operational jobs when the entire project is in operation. According to ABC's September 18 account, the work includes mechanical, electrical and control systems, security, and information and communications technology. Construction will also require workers, potentially creating new demand for local companies and skilled personnel. However, employment figures must be compared on a consistent basis. Combining construction workforce requirements with operational jobs, or direct with indirect employment, can suggest more hiring than would actually occur. Estimates based on the entire development should not be interpreted as hiring plans for the first building.
The developer explains that its employment outlook is based on an economic benefits assessment by Urbis and varies with project phases, timing, occupancy and operating conditions. These are estimates used to evaluate the plan, not a tally of employment contracts already signed.
Local reporting by The Guardian on October 5 said some residents, remembering the earlier gas development boom and subsequent changes, were asking about long-term benefits for the region. Alongside electricity and water, local infrastructure and community consultation were identified as concerns. These concerns are difficult to interpret simply as opposition to technology. What matters to residents is how much of the total investment will translate into local jobs and business, and whether benefits will continue after construction ends. More specific hiring, training and local procurement plans for each development phase would provide a clearer basis for assessment.
Queensland's data center approval framework is changing. ABC reported on October 2, 2026, that the state government had announced it would introduce a new framework for data center planning and assessment. The report also described a move toward requiring social impact assessments and community benefit agreements with local governments. However, in the same report, Western Downs Mayor Andrew Smith said the state government had told the council it would retain its role as the assessment manager for this project. A general announcement of regulatory changes must be distinguished from the handling of an individual project whose application has already been submitted.
Australia's federal government also published Expectations of Data Centre and AI Infrastructure Developers on March 23, 2026. The policy document calls for consideration of the energy transition, sustainable water use, domestic skills and jobs, and community benefits. It explicitly states that it operates alongside existing legislation and does not alter legal compliance obligations. A claim that a project aligns with policy therefore does not mean development permission, grid connection or water-related approvals have been secured. Investment announcements and individual approval outcomes must be checked separately.
Western Downs Digital Park shows how directly the AI industry depends on extensive land, generation facilities and local labor. Digital services require not just buildings and servers but also electricity networks, cooling equipment, water sources and construction supply chains. The lessons for South Korea extend beyond the size of the investment. The scale of the entire campus must be distinguished from that of the first phase, maximum power from annual consumption, and grid costs from market effects. Water demand during normal operations must likewise be separated from demand during construction and drought.
What can currently be confirmed is a major development plan, a first-phase lease agreement and the developer's proposals for employment, water and energy. Actual consumption, employment outcomes and electricity price effects have not yet been verified through operating results. The next criteria for assessing the project are clear: when and how the required electricity will be secured, whether water supplies can be maintained during dry periods, and under what conditions the benefits presented to local residents will be delivered. The success of this AI data center planned for rural Australia depends not only on the scale of its servers but also on translating these commitments into specific contracts and approval conditions.
