New data centre rules could set a global standard

Australia is in the midst of a data centre boom, one that promises to redefine the nation’s digital landscape and economic future. Fuelled by more than $26 billion in forecast investment and a projected doubling of national capacity by 2030, this wave of infrastructure expansion is undeniably exciting. But as we lay the foundations for this growth, one imperative must remain central: it cannot come at the cost of sustainability.

As of 1 July 2025, all data centres hosting federal workloads are required to meet a minimum 5-star NABERS Energy rating under the Australian Government’s Net Zero in Government Operations Strategy. This builds on earlier guidelines and cements energy efficiency as a non-negotiable baseline, not just for government data centres but increasingly as a benchmark across the entire sector.

This marks a defining moment. As demand for digital infrastructure accelerates, driven by AI, cloud computing and government workloads, the energy footprint of data centres is growing rapidly. We’re no longer talking about marginal increases but a fundamental shift in how these facilities are planned, powered and operated. At Schneider Electric, we see these new regulations not as a constraint but as a catalyst.

Efficiency standards: from burden to business case

Historically, energy efficiency mandates have been viewed through a compliance lens. Today, they represent competitive advantage. A 5-star NABERS rating, or a power usage effectiveness (PUE) of 1.4 or lower, is increasingly demanded by ESG-focused clients, hyperscalers and government partners. Meeting these standards requires integrating smarter technologies, more sustainable cooling solutions, and renewable energy sources from day one.

This is where digitisation, monitoring and AI-driven optimisation can shift the narrative, from reactive compliance to proactive performance. By embedding real-time visibility and control into facility design and operations, data centres can drive down emissions and operating costs simultaneously.

Emerging technologies are helping operators build smarter, more scalable and efficient systems from the ground up. These capabilities are essential for meeting today’s performance needs and tomorrow’s AI-driven demands. At Schneider Electric, we’ve seen this firsthand through integrated solutions that focus on modularity, data visibility and resilience.

Grid resilience and renewable integration

Australia’s transmission networks are under pressure from the rising electricity demands of data centres. In response, the Australian Energy Market Commission (AEMC) is progressing major reforms to grid connection standards. In May 2025, it finalised new rules to streamline renewable energy connections and launched consultation on a second package focused on large energy users, particularly data centres and hydrogen projects.

These proposed standards will require data centres to remain stable during grid disturbances and support system security, reflecting their growing impact on electricity demand. As connection risks and compliance requirements increase, developers are turning to innovative models, such as co-locating with renewables and batteries, to enhance flexibility and reduce pressure on the grid.

Australia’s global moment

Australia’s position is unique. With liberal access to AI, geographic proximity to Asia and deep renewable energy potential, we’re poised to become a regional hub for sustainable digital infrastructure. However, the window to lead is narrow.

By adopting bold regulatory standards now, like the net-zero procurement requirements, 100% renewable electricity targets by 2030 and robust emissions reporting frameworks in the Australian Public Service, the federal government is sending the right market signals. This creates both opportunity and obligation for industry to accelerate innovation.

If we get this right, Australia won’t just be building more capacity. It will be building a sustainable, competitive edge that lasts for decades.

What’s next

The onus is now on developers, operators and technology partners to rise to the challenge. The regulatory foundations have been laid, the technologies exist and the economic and environmental stakes are high.

Let’s ensure that Australia’s data centre boom doesn’t just drive digital transformation but powers a cleaner, more resilient and equitable energy future.
