Data centre demand to reach 34TWh by 2036, AEMO reports

AEMO forecasts data centre electricity demand will rise from 5TWh to 34TWh by 2035, 36. The jump reflects Australia's emergence as a regional hub for computing, driven partly by AI workloads and global demand for data services.

Where this fits

Data centre load is firm, continuous, and growing fast. It sits at the core of the reliability problem: Australia is building a renewables-heavy grid while demand from computing, electrified transport, and industry is becoming less predictable and more baseload-intensive. A solar and wind fleet cannot meet this load profile without either massive overbuild and storage (a materials and cost problem) or continuous gas firming (an emissions and cost problem). Nuclear plants, running at 90% capacity factors with no weather dependency, are what the grid needs for this load shape. They are banned by law.

What it means

Australia is committing to a seven-fold increase in data centre power at the exact moment the grid is most exposed to firming cost and supply-chain risk. Meeting 34TWh of new data centre demand with renewables means building far more solar and wind capacity than the energy numbers suggest, plus batteries or gas on standby. Both paths are expensive and both depend on supply chains dominated by China. A firm, domestically operable nuclear fleet would reduce that dependence, lower whole-system cost, and deliver the kind of power data centres and other firm loads actually need. Instead, Australia is locking in weather-dependent supply and the gas plants required to back it up.
