The buildings that run AI tools are not small. A single large data centre can draw as much power as a mid-sized city. Australia now has more than 270 operating or planned, and that number is growing fast. The country has become one of the most attractive destinations in the world for this kind of investment, partly because of its geography, political stability, and land availability, but mainly because of the AI boom driving demand from companies in Asia and the Pacific.
The numbers behind this are hard to ignore. Australia's data centre capacity is expected to grow more than tenfold between 2024 and 2035. At that scale, data centres could represent up to 11 percent of the country's total electricity use. Without a coordinated policy response, that demand would simply land on the existing grid, pushing up prices for everyone else.
The Australian government, together with all state and territory energy ministers except Queensland, has agreed that new data centres must fully offset their electricity demand by funding new renewable generation and storage in the same state where they operate. This goes further than simply buying green energy certificates from existing solar farms. The idea is that each new facility has to bring genuinely additional clean energy into the system, not just claim a share of what is already there.
This is a meaningful distinction. In many countries, companies buy certificates that represent renewable electricity generated somewhere in the grid, without any guarantee that new capacity was built. Australia is moving toward requiring that the renewable capacity actually exists and was built to serve the new demand. Modelling from the Clean Energy Finance Corporation found that an additional 3.2 gigawatts of renewable capacity and 1.9 gigawatts of battery storage by 2035 would be enough to contain both price rises and additional emissions from the data centre surge.
The Queensland holdout is the story within the story. Since coming to power in late 2024, the state's LNP government scrapped its renewable energy targets and committed $1.6 billion to keeping coal plants running until at least 2046. It is now planning to more than double its gas generation capacity. The state's position at the ministerial meeting was not an objection in principle but a demand for more cost and benefit detail before committing. That may sound reasonable, but it is the same state that has already made its energy direction clear.
The practical consequence is fragmentation. If Queensland remains outside the agreed framework, data centre developers face a patchwork of rules depending on which state they build in. Some will choose Queensland precisely because the conditions are less demanding. That is good for Queensland's short-term investment pipeline, but it means the energy cost of those facilities lands on the existing grid rather than being offset. Queensland households and businesses would eventually absorb part of that cost.
This is not a uniquely Australian problem. In parts of the United States, areas with high concentrations of data centres have seen wholesale electricity costs rise sharply in recent years. In the UK, modelling suggests that data centre demand could push power prices up nearly 10 percent by 2040. The global pattern is consistent: when large new loads connect to a grid without matching supply, prices go up and existing consumers pay.
The irony is that handled well, data centres could actually accelerate renewable energy investment rather than slow it down. These facilities run continuously and need reliable power, which makes them excellent long-term customers for new wind and solar projects that might otherwise struggle to find buyers. A data centre that builds its own solar farm and battery storage is, in effect, funding new clean energy infrastructure that also stabilises the broader grid.
Amazon has already announced plans to invest the equivalent of around $13 billion in Australian data centre infrastructure over five years, including eleven renewable energy projects across three states. Microsoft's chief executive made a separate $25 billion, three-year commitment to Australian digital infrastructure. These are not companies that need to be dragged toward renewable energy. They are already moving in that direction because their global customers and investors expect it.
The real risk is not that the large tech companies resist these rules. It is that the policy stays soft and voluntary long enough for a generation of mid-tier developers to build facilities that lock in fossil-fuel dependency for decades. The Australian government's current framework is described as a set of expectations rather than legally binding requirements. Queensland's non-participation is a signal that the pressure to keep those expectations voluntary will not go away.
