Nvidia’s 2 GW Australia Plan Hits a Power Deadline

Nvidia is targeting up to 2 GW of AI data centre capacity in Australia by 2027 with eight local operators. The plan is for land, power and empty shells that can take several generations of its DSX systems.

The date is doing more work than the chips. Industry research still has the entire national fleet at 1.9 GW that year, Canberra is writing rules that make new halls pay for new generation, and the largest campus named in the release is not due to take power until 2028.

Nvidia Dates a 2 GW Australian Build for 2027

On 9 September 2026, Nvidia said it is working with Firmus, Sharon AI, IREN, Megaport, ResetData, CDC, NEXTDC and AirTrunk to expand the physical base for AI factories, with up to a 2-gigawatt buildout by 2027. The operators run the sites. Nvidia supplies the DSX platform, chips, networking, software and the reference design.

DSX is Nvidia’s full-stack factory kit, spanning the building, the computers, the network, the software and the drawings operators copy. The company says software updates can keep those halls useful across more than one generation of silicon, which is how it wants landlords to treat the rooms as a long-lived asset rather than a one-chip bet.

Raj Mirpuri, vice president of global AI clouds and infrastructure ecosystem at Nvidia, put the power problem in the first line of the pitch.

AI factories turn energy into intelligence, the essential resource of the AI economy.

The same statement says extra Australian capacity will help local firms train models at home “while supporting additional power generation projects” for regional and global demand. Software names already on Nvidia’s Nemotron open models include Heidi in health and Atlassian’s Rovo search. The scarce inputs in the release are still land, power and shell, not model weights.

1.9 GW Is the Industry’s 2027 Number

Data Centres Australia and analysts DC Byte, in a forecast current at 31 March 2026, put Australia at 1.5 GW of operational capacity across 162 live sites. That is the fitted-out IT load available for use, not the much larger stack of proposals on planning portals.

Their year-by-year path for halls that are actually on is slower than Nvidia’s 2027 banner. National operational capacity was 1.4 GW in 2025. They expect 1.7 GW in 2026, 1.9 GW in 2027, 2.3 GW in 2028, 2.7 GW in 2029 and 3.2 GW in 2030.

THE DC BYTE OPERATIONAL FORECAST

Nvidia’s 2 GW target for 2027 therefore sits 0.1 GW above the figure those researchers give for every live hall in the country, AI and otherwise. Either the 2 GW is mostly capacity already inside that 1.9 GW path, or the operators would have to outrun the model by a wide margin in a single year.

The wider ledger explains why headlines run hot. DC Byte’s pipeline total is 21.6 GW, but 16.8 GW is early stage, 3.1 GW is committed, and only 0.2 GW is under construction beside the 1.5 GW already on. Sydney accounts for 11.4 GW of that pipeline and Melbourne 9.0 GW. Of 90 pipeline sites, 47 are listed above 100 MW, against three operational sites in that class among 162. A lot of paper megawatts have not bought a transformer.

The Eight Partners Already Hold Most of the Steel

Nvidia is not opening a greenfield campus of its own. It is putting a DSX badge and a 2027 date on operators who have been contracting power for months. Several of the megawatt figures in the release were already public.

THE EIGHT NAMED OPERATORS

• Sharon AI: Up to 68,000 Nvidia GPUs, linked with Quantum InfiniBand and Spectrum-X Ethernet, on the DSX platform for startups, companies and research groups.
• IREN: Applying the DSX blueprint across its portfolio, including an 800 MW campus at Bundey in South Australia.
• CDC: More than 550 MW across Australia and New Zealand, with a further 800 MW under construction, using direct liquid-to-chip cooling.
• NEXTDC: 740.1 MW of contracted utilisation at 30 June 2026, with a 565.1 MW forward order book still to bill, after 495.3 MW of new contracts in FY26.
• Firmus: Expanding Project Southgate for hyperscale and AI-native demand in Australia and Asia-Pacific.
• Megaport, ResetData and AirTrunk: Adding inference access, sovereign cloud halls and AI-ready powered shells with direct-to-chip liquid cooling.

Greg Boorer, founder and CEO of CDC, said the group’s sites use 100% renewable electricity and “pioneering zero water advanced cooling technologies certified for NVIDIA accelerated computing infrastructure.” Oliver Curtis, cofounder and co-CEO of Firmus, called Southgate “a tangible commitment to building Australia’s AI future.” James Manning, cofounder and CEO of Sharon AI, said gigawatt-scale factories only become “real capability when organizations can access world-class compute without compromising on security or sovereignty.”

Those quotes are about access and design. They do not move a 2027 energisation date. Liquid-cooling plants are long-lead kit, with chiller orders often running 20 to 60 weeks and coolant distribution units 16 to 52 weeks, so a hall that is supposed to be hot in 2027 needed fabrication tickets in 2026. The 2 GW figure is a planning envelope. It is not a meter reading.

The Underwrite Law Misses a Lot of This Steel

On 15 July 2026, Prime Minister Anthony Albanese said large data centres would face Australian Standards covering siting, energy and water. The standards include a legal duty for operators to underwrite their own new power supply, pay their full share of grid connection so household bills are not hit, cut power when the grid needs it, and keep water use down.

We will create a legal obligation for the next generation of large-scale data centres to underwrite new power supply.

Anthony Albanese, Prime Minister of Australia, 15 July 2026

In the same set of remarks he said new centres should put at least as much energy into the grid as they take out, as net generators rather than net users, and should pay for extra water works. He also said the rules are for new proposals. “You can’t retrofit.”

National Cabinet on 26 August 2026 agreed that large centres bring material energy, water and land-use impacts. The Commonwealth said it would legislate nationally consistent standards in early 2027, designed to sit beside state planning rather than replace it. That is the same calendar year as Nvidia’s 2 GW date, and after a large share of the named capacity was already contracted or in the ground.

THE POWER RULES CALENDAR

1. 23 March 2026: The government publishes Expectations of data centres and AI infrastructure developers, including underwriting new renewable supply and paying full connection costs.
2. 15 July 2026: Albanese announces Australian Standards for large centres and sets up an Office of AI in the Department of the Prime Minister and Cabinet.
3. 26 August 2026: National Cabinet backs national energy, water and land-use standards, with Commonwealth legislation intended for early 2027.
4. 9 September 2026: Nvidia dates a 2 GW DSX buildout with eight Australian operators.
5. 14 September 2026: NSW submissions close on who pays for data-centre grid works.
6. Early 2027: Planned window for the Commonwealth AI standards law, aimed at new proposals.
7. 2028: IREN’s Bundey campus is due to start taking power.

If the statute really does apply only to new proposals, a 2027 banner built from 2025 and 2026 contracts can miss the underwrite. Nvidia still needs the electrons. Saying the expansion will support extra generation does not, by itself, put turbines on a timetable.

NSW Is Hearing 28 GW of Connection Requests

New South Wales is where the queue is loudest. The state’s energy department opened consultation on 17 August 2026 on how data centres connect and who pays for the wires. Submissions close at 5:00 pm AEST on 14 September 2026, four days after Nvidia’s note, under reforms meant to stop network costs leaking onto households and small firms.

As of July 2026, the consultation page says data centres are seeking up to 28 gigawatts of connections. About 13 GW is in advanced talks. The department says 13 GW is more than average daily electricity demand in NSW.

THE NSW CONNECTION QUEUE

• Seeking capacity: Up to 28 GW of data-centre network connections as of July 2026.
• Advanced talks: Around 13 GW, a load the state says exceeds its average daily demand.
• What the reforms target: Faster, clearer connections, cost recovery from the halls that cause the upgrades, and backup for NSW planning guidelines.

AEMO’s 2026 Step Change case, as set out by the Climate Council, puts data centres at around 3% of National Electricity Market demand now and 13% in 2036. A year earlier, that 13% share had been a 2050 problem in AEMO’s work. Modelling for the Clean Energy Finance Corporation, cited by the Climate Council, found wholesale prices could rise more than 20% by 2035 if the extra load is not matched with new renewable plant and storage, because the gap gets filled with gas.

NEXTDC told investors in its 27 August 2026 results pack that both NSW and the Commonwealth were proposing reforms on data-centre grid connections and energy use, with the NSW consultation closing on 14 September 2026. The listed operator is already inside Nvidia’s partner list, and already warning the same room about the rulebook.

Sydney Water Is Seeing 40 Million Litres a Day

Power is the binding constraint. Water is the one that shows up in dry summers. Industry figures collated by the Climate Council put current data-centre water use at under 0.1% of national supply, 0.7% in Sydney and 0.2% in Melbourne. The same industry path has demand more than tripling from 5.5 GL to 17 GL over five years, reaching 1.9% of Sydney’s supply and 0.9% of Melbourne’s by 2030, and those paths do not include every recent proposal.

Sydney Water has been taking applications and enquiries for single centres to use up to 40 million litres a day, equal to 16 Olympic pools. Operators say they apply for a worst-case volume they rarely draw. The pipes still have to be sized for the application. Albanese’s July package requires centres to cut water use, lift energy efficiency, and pay for extra water infrastructure.

CDC is already selling a different cooling stack, with Boorer pointing to certified zero-water systems for dense Nvidia gear. Direct liquid-to-chip loops move heat into plant rooms instead of evaporating it in open towers, which is why every partner note in Nvidia’s release mentions liquid cooling. The design choice is also a permit choice. A hall that still needs a 40-million-litre water file will have a longer argument with Sydney than a closed loop that does not.

The Climate Council also notes that specialised operators already offset about 70% of energy use with renewables on a voluntary basis, because the price of wind and solar beats the alternative. The fight in 2026 is over additionality: whether a 2 GW AI load retires a coal unit later, or simply soaks up plant that households were already going to need.

Why Bundey Cannot Meet a 2027 Switch-On

The single hardest megawatt figure in Nvidia’s Australian list is IREN’s 800 MW Bundey campus. On 3 June 2026, IREN said it had signed a transmission connection agreement for that site, about 78 miles northeast of Adelaide, with four 330 kV feeder exits that it expects will support 800 MW without network upgrades. It also said the campus is on track to begin energization from 2028.

Daniel Roberts, cofounder and co-CEO of IREN, said the DSX reference architecture “provides a repeatable blueprint to bring capacity online at scale,” and that Bundey is where that blueprint lands in South Australia. The blueprint does not move 2028 to 2027. If Bundey is inside the 2 GW story, a chunk of the headline capacity is a year late for Nvidia’s own date. If it is not inside the 2 GW, the remaining partners have to carry even more of 2027 on halls that are still waiting on chillers, permits and unused 16.8 GW of early-stage paper.

IREN said Bundey should create more than 200 ongoing skilled jobs and more than 500 roles during construction, and pointed to South Australia’s aim of 100% net renewable electricity by 2027. That state target is useful marketing for an AI campus. It is not a spare 800 MW sitting in a substation today.

The 2 GW Australian build will happen in some form, because the operators already hold land, contracts and, in CDC’s case, 800 MW of extra halls under construction. What will not happen on the face of the release is a clean doubling of the live national fleet by 31 December 2027, under a new underwrite statute that has not been written, on a New South Wales grid still taking submissions on 28 GW of wishes, with an 800 MW flagship that is not due to warm up until 2028.
