Why AI Companies Need Data Centres
Synopsis
Artificial intelligence relies on large-scale data centres to process workloads, driving new investment in Australia's digital infrastructure. As electricity demand rises, governments, energy providers and technology companies are reshaping how AI facilities are built, powered and connected, creating both opportunities and challenges for businesses and investors.
For every time you send an email, create an image or analyze a data set to an AI, a huge physical response takes place thousands of kilometers away. Artificial intelligence's user interface is invisible and seamless, but behind it is a voracious appetite for heavy industrial power.
The AI model doesn't reside in a nebulous digital cloud, it resides in extensive high-voltage server complexes. This is the reason for the need of data centres in the world of Artificial Intelligence.
The technology has matured from software novelty to a permanent economic force, and Australia is experiencing an unprecedented infrastructure boom that is fast transforming the country's energy grid and creating new opportunities for investors.
Traditional Cloud versus AI Factories
For example, traditional Internet usage, such as e-mailing, viewing video streams or a typical business application is intermittent. As a result, traditional hyperscale data centres utilize common servers to distribute web traffic among them.
AI is on a whole new level. An AI system capable of learning on a massive scale demands a lot of computer power, enough to power a system running full time for many months. It has led to a new form of infrastructure that is referred to as AI factories.
These modern facilities have the following unique features:
- Extreme Heat and Power: AI servers fit a lot more components into each rack, and require significantly more electricity to run and generate a lot more heat. It's no longer enough for standard air conditioning systems and advanced liquid cooling systems are being adopted in facilities.
- Flexible Locations: AI factories are not necessarily built in major cities to beat the latency of everyday users; unlike regular cloud applications. This provides developers an option to develop them further away from population centers, near to regional clean energy resources.
Leaders in technology around the world, such as Microsoft, Amazon, OpenAI and Anthropic, have all responded by developing their own AI computing initiatives in Australia. There are approximately 90 other data centre projects in the development pipeline around the country.
Rising Electricity Use and Price Projections
These upcoming giant facilities are pushing energy operators to reconsider the country's energy future. For example, the proposed 1.2 gigawatts (GW) of power for the proposed Mamre Road Data Centre campus in Western Sydney is expected to exceed the power consumption of Australia's biggest industrial facilities, including the Tomago Aluminium Smelter.
New data from the Australian Energy Market Operator (AEMO) reveals data centres are quickly moving from a small power user to a large power consumer.
| Timeline | National Electricity Grid Usage | Share of Total Grid Consumption |
| Past State (2024–25) | ~4 Terawatt-hours (TWh) | Roughly 2% of the main grid |
| Projected Horizon (2030) | ~12 Terawatt-hours (TWh) | Expected to triple to ~6% |
| Long-Term Forecast (2049–50) | Continued upward trajectory | Projected to reach around 12% |
The Impact on Bills
The Climate Council warned that there was a major risk if this sudden influx of data centres wasn't matched by a similar acceleration in the rollout of new renewable energy projects, average wholesale electricity prices could go up more than 20% by 2035, which will ultimately make itself felt on household power bills.
Shifting energy policies and government action
The Australian Government amended its strategy in response to possible pressure on electricity costs for the community. Federal policy will no longer endorse data centre investments on a blanket basis, but will now impose specific conditions on these large-scale investments. In March 2026, the government unveiled its official policy document, Expectations of Data Centres and AI Infrastructure Developers.
In this model, developers must actively try to minimize their effects on the community, or are approved through a fast-track process. The key rules are:
- Paying for Connections: Operators will have to pay for the infrastructure they need to install in their own physical power lines and grids rather than regular electricity consumers.
- Secure New Clean Energy: Companies must sign new dedicated wind or solar farms or battery systems to offset their carbon-heavy power usage, instead of just purchasing carbon offset certificates on paper.
- Conserving Water: Data centres consume millions of litres of water to cool servers, so developers need to demonstrate that they're running highly efficient, closed-loop, recycling systems or systems that use water that is not consumed for drinking.
Opportunities and Risks for ASX Investors
The construction frenzy presents investors on the ASX with obvious opportunities in some areas, but also some risks to watch out for:
- Construction and Specialized Engineering: Complex installations are required for the building of high-density AI factories, with regards to electricity and liquids. This helps to create a gradual income flow for specialized commercial contractors and manufacturer companies.
- Renewable Utilities: Data centres are consuming vast quantities of clean energy to meet government standards and renewable energy companies and commercial battery manufacturers are signing long-term secure power supply contracts.
- The 'Phantom Demand' Warning: Speculative applications, often referred to as phantom demand, drive the current waiting list for grid connection, according to analysts. Some projects can be applied for and may never be funded or constructed; investors should check for actual progress on construction.
What to Watch Next
New South Wales and Victoria are set to continue in the middle of all the problems over the next few years as more large data centre power approvals will need to go through.
In years to come the soft approach to voluntary green targets will become a hard one, and we should probably be betting on the organisations that put this into practice right from the beginning.
