Australia's data centre plans can become a blueprint for the world

If I told you Australia could take sunshine and turn it into our nation’s next driver of productivity and prosperity, it might sound a stretch.

It’s a simplified analysis but it underlines a fundamental truth. Australia has exported the value of what lies beneath our feet for decades. Our next great export opportunity could come from above, converting renewable power into compute and digital services.

For this to happen, the once-in-a-generation data centre build-out must also include a significant expansion of clean energy, and the grid infrastructure and energy management systems that data centres depend on.

New data centre standards proposed by the National Cabinet can set the bar for other jurisdictions to learn from and ensure benefits from development are shared broadly.

The chips are down

A year ago, the Australian Energy Market Operator (AEMO) was tracking 97 potential data centres. Today, the figure is 225. To call this a boom understates the speed of change.

Not all will be built. But the direction is clear. Data centres are becoming essential economic infrastructure. Estimates suggest their accelerating construction could see investment of $150 billion by 2030. When combined with the potential $200bn energy transition investment pipeline, the total approaches 13% of GDP, rivalling the scale of the mining investment boom in the 2000s.

This presents both a generational economic opportunity, and a significant infrastructure challenge.

Mining for lessons

Like mining, this investment boom could provide economic benefits for generations.

While the comparison is useful, it comes with lessons. Attracting data centre investment is not the same as capturing long-term benefits. Creating lasting value requires renewable generation, storage, water infrastructure, skills, and digital capability built around them.

That is why the federal government standards, alongside state-based frameworks like the NSW Data Centre Policy, matter. They create an opportunity to attract globally mobile investment while setting clear expectations that growth must benefit our people and country. That is a much stronger proposition for communities.

A responsible approach

Data centres currently use around 3% of electricity, but AEMO is forecasting it could hit 13% in a decade. Roughly 70% of the energy used today is provided by renewable energy through power purchase agreements (PPAs) and large-scale generation certificates (LGCs).

While comparable to other sectors or emerging needs like the electrification of transport and businesses, it illustrates the responsibilities the industry must take seriously.

As demand grows, communities are entitled to expect that investment in digital infrastructure is matched by investment in the systems that support it. New data centre demand should not compete with existing households and businesses for power. Supporting investment in new grid-scale renewables, storage and demand-response — as recommended by the Australian Energy Market Commission — can avoid this.

Real-time energy monitoring can show operators where electricity is being used and where capacity is available. Data centres supporting healthcare, banking, government and other critical services need continuous, reliable power, but the objective should be to use flexibility where technically possible, while maintaining resilience for services Australians depend on.

Turning the tide on community concerns

Communities need confidence that developers are using the best available solutions, to minimise areas of concern like noise, water use or emissions. Standards should be set to create outcomes, not mandate technologies, as there’s no silver bullet that’s right for every facility.

A range of technologies to make data centres meaningfully more efficient already exist. Recycled water can reduce pressure on drinking-water supplies. Closed-loop cooling systems re-circulate coolant rather than continually drawing water. Real-time monitoring can identify wastage and automatically adapt operations to improve efficiency.

More transparency about how water is used and where it comes from will also help. Data centres remain a relatively small water user at a national level, with one estimate putting it as low as 0.04% of Australia’s drinking water. However, national averages can obscure local pressure. Approaches like developing centres near wastewater plants (to use recycled water) and disclosing water consumption can bring clarity to the debate.

Setting a new standard

Australia is not the only country working through these questions.

Around the world, governments and communities are weighing the economic benefits of data centres against their impacts on resources and local infrastructure. Projects face opposition where communities don’t believe benefits or costs are shared fairly.

Australia can now demonstrate a better model. If data centre growth brings new renewable supply, invests in energy and water infrastructure, uses resources transparently, and deploys the most efficient technology, communities will see more than a big new building competing for supplies.

They will see investment that makes our country stronger, and which improves productivity, innovation and national competitiveness.

Even better, it might let us take the world’s most abundant resource — the sun — and turn it into national wealth. I believe that’s a forecast everyone can get behind.
