By 2035-36, that number is expected to hit 34 TWh, roughly a sevenfold increase that would push data centers to 13% of total national consumption. To put that in perspective, the entire NEM is projected to grow about 40% over the same period, reaching around 250 TWh. Data centers alone would account for a disproportionate chunk of that growth. ## The numbers behind the surge The Australian Energy Market Operator, the body responsible for managing the country’s electricity and gas systems, recently doubled its count of data centers in development from 97 to 225. AEMO’s earlier models had anticipated data center demand reaching roughly 12 TWh by 2030. Those projections have been revised sharply upward, driven largely by the accelerating computational appetite of artificial intelligence workloads. Capacity forecasts from the Clean Energy Finance Corporation paint a similar picture. CEFC projects that data center capacity will grow from 1.35 GW today to somewhere between 4.7 and 7.4 GW by 2035. The geographic hotspots for this buildout are concentrated around Sydney, Newcastle, and Melbourne. Sydney in particular has been a magnet for hyperscale operators, though grid constraints in western Sydney are already forcing developers to look at alternative sites. ## A $135 billion infrastructure question Meeting this demand won’t come cheap. Total investment in data center infrastructure could reach up to $135 billion, a figure that encompasses not just the facilities themselves but the energy generation, transmission, and cooling systems required to keep them running. AEMO’s decision to treat data centers as a distinct planning category signals that regulators see them as fundamentally different from traditional industrial loads, with faster ramp-up timelines, higher reliability requirements, and concentrated geographic demand that can strain local grid infrastructure. ## Why this growth is happening now The obvious catalyst is AI. But AI isn’t the only driver. Cloud migration across Australian enterprises, the expansion of streaming and digital services, and growing data sovereignty requirements that mandate certain government and financial data stay onshore are all contributing to the demand spike. Australia’s geographic position also makes it a natural hub for serving the Asia-Pacific region. ## What this means for energy markets and beyond The mismatch between data center timelines, which can move from approval to operation in 18 to 24 months, and transmission infrastructure timelines, which often stretch to five or more years, is one of the biggest risks to the entire buildout. Global hyperscalers like Amazon, Microsoft, and Google are all expanding their Australian footprints, but so are regional players and sovereign cloud providers. **Disclosure:** This article was edited by Editorial Team.
