NextDC’s record AI demand meets Australia’s power constraints

On August 27, NextDC, an Australian data center operator, announced it has seen its best contracting performance so far, increasing the amount of contracted capacity by three times to 740.1 MW and posting a profit for the year again as the AI infrastructure boom puts increasing pressure on power and water supplies.

According to the data(ASX: NXT), contracted utilization surged by 202%, and capital expenditures reached A$3.4 billion, twice the expenditures recorded previously, as the company hurried to meet customer requirements.

As far as the overall AI market is concerned, the data represents how quickly computing needs are turning into electricity consumption. As per the estimates by Gartner, global data center consumption will increase from 447 terawatt-hours in 2025 to 565 terawatt-hours in 2026, which means a 26% growth. AI-optimized servers will make up 31% of that consumption.

According to McKinsey, the data center construction rates will grow even faster. The total amount of energy required by the world’s data centers is estimated to increase from about 82 gigawatts in 2025 to around 220 gigawatts by 2030. It is expected that the amount of energy needed, particularly by AI, will grow from 44 gigawatts to 155 gigawatts, which is approximately 70% of the entire demand.

Why the profit beat is not quite what it looks like

NextDC swung from an A$60.5 million loss in financial year 2025 (FY25) to an A$82.1 million statutory profit for the year ended June 30, 2026.

The change in accounting significantly contributed to the rise in profit. Several contracts with customers were reported as operating leases, with their underlying assets treated as investment property valued at fair value. This helped create a fair value gain of A$128.8 million.

Additionally, the core business also showed improvement. Net revenue grew by 16% to A$405 million, as well as underlying EBITDA. which went up by 15% to A$248.8 million, which is higher than NextDC’s original expectation. The billing utilization increased by 58% to 175.0 megawatts.

The capital behind the capacity

Craig Scroggie, the Chief Executive Officer, described the company’s FY26 as one of execution.

“FY26 was the largest contracting year in NEXTDC’s history.”— Craig Scroggie, Chief Executive Officer and Managing Director, NEXTDC, FY26 Results Announcement

He also highlighted the Forward Order Book of 565.1 megawatts, which is over three times the company’s current billing utilization. According to NextDC, these commitments are binding contracts and not merely options, reservations, or opportunities in the pipeline.

Building that capacity will be an expensive exercise. Capex was A$3,397 million—A$397 million above the top guide, which had itself been raised thrice.

Since August 2025, NextDC has secured A$9.75 billion of new capital, which has seen pro forma liquidity grow from A$5.5 billion to A$8.7 billion. KL1 in Kuala Lumpur was opened in May 2026 to a foundation customer, and work has now begun on TK1 Tokyo.

According to McKinsey, global cumulative expenditures related to data centers (excluding servers, GPUs, and IT hardware) could surpass $1.7 trillion through 2030.

Where the grid pushes back

That momentum is meeting increased grid constraints. NextDC reported that New South Wales (NSW) and the Commonwealth are looking at revisions to the connection of data centers to the power grid and their energy consumption. The consultation process in NSW is expected to close by September 14, 2026, with recommendations from the national level expected to come into effect starting in 2027.

According to a report by Oxford Economics Australia in association with AEMO, National Electricity Market data center usage is expected to go up from 5.1 terawatt hours in FY26 to 15.5 terawatt hours by FY30 and to 33.7 terawatt hours by FY36. NSW and Victoria are estimated to account for over 85% of this electricity usage.

According to McKinsey, the biggest contributor to the discrepancy in operating costs of AI colocation industries is electricity usage. Presently, the waiting duration required to connect to a grid is believed to be four years. Moreover, some sites face delays that can last as long as ten years. Since 2019, lead times for chillers, transformers, generators, and switchgear devices have more than doubled and can take more than three years.

The Australian Energy Market Commission has recommended that data centers bring new renewable generation, secure firming capacity and provide greater demand flexibility.

“Very large loads need to be planned, connected and operated as part of an integrated system.”— Anna Collyer, Chair, Australian Energy Market Commission

The political backdrop for AI power

The tension extends well beyond Australia. As Cryptopolitan reported on August 7, President Donald Trump said data centers could become a larger industry than oil. A Gallup poll found that 71% of Americans oppose large data facilities near their homes, including 48% who strongly oppose them.

Texas Governor Greg Abbott has also ordered regulators to pause some projects while auditors assess their electricity needs, water use, cooling systems, incentives, and community impact.

That is the environment NextDC is scaling into. Its rising energy and water use alongside record contracting captures the central tension of the AI infrastructure boom: demand is real and already being booked, but power availability, regulation and public acceptance increasingly determine how fast that demand can be turned into working capacity.
