THE CAPACITY PICTURE
Follow the capacity.
National market context, documented sites and the development pipeline.
Australia · DOCUMENTED OPERATING CAPACITY
≈ 1,096 MW
Operating computing power supported by site and operator disclosures.
696.95 MW allocated to named sites + 399.05 MW disclosed at portfolio level.
Sites already included in a portfolio are counted once. Observations retain their own dates; this is not a complete national census.
See every operator, site and source →Australia · published national benchmark
≈ 1.5 GW
National operational capacity
≈ 1,500 MW IT · 31 March 2026
162 centres · Operational data centres in source inventory
Data Centres Australia and DC Byte estimate Australia had about 1.5 GW of operational IT capacity across 162 data centres at 31 March 2026. This provides a national market benchmark alongside the Atlas’s partial site-level evidence.
The national estimate is a separate benchmark. It is not added to the documented capacity above, whose coverage and observation dates differ.
Definition and scope
Operational capacity is the IT load supported by fitted-out halls available for use, not necessarily utilised capacity or live electricity demand. This rounded industry estimate has its own inventory and date. It is not an independently reconciled Atlas facility total and is never added to site subtotals or assigned to map pins.

DOCUMENTED CAPACITY · SELECTED SITES
Partial capacity subtotals across the selected sites. Figures cover the selected records. 29 sites have no comparable power disclosure. Built capacity is not utilisation or available supply. Operating capacity & market context → Read the methodology → · Coverage & research gaps → · Wider pipeline & source reconciliation → Portfolio disclosures can exceed the amount allocated to named sites here. See NEXTDC’s reconciliation →
What do these megawatts actually mean?
MW measures electrical power. Here it means power available to servers, GPUs, storage and networking equipment, excluding cooling and other building overheads. The industry calls this “IT power”, short for information technology. It does not tell you how many GPUs are installed, how fast they are, how much power is being used, or how much capacity is available to buy. Planned figures include proposed and approved design envelopes, including expressly labelled ceilings. They are not a delivery forecast. Grid connections, building power and MVA are shown separately in the pipeline evidence.
