Datacentre Powerdraw and Heat Calculator

Size a GPU build against real datacentre sites, and see how they connect to the grid - across all eight states and territories, from Sydney and Melbourne to the 2.16 GW Dalby campus in Queensland and IREN's 800 MW Bundey campus in South Australia. Hardware baselines: NVIDIA DGX H100/H200 user guide (10.2 kW per node, 38,557 BTU/hr, 1105 CFM), NVIDIA DGX GB rack guide (~120 kW per GB200 NVL72 rack) and HPE GB300 NVL72 datasheet (132-140 kW per rack). Grid data: AEMO 2026 ISP, Transgrid RSNWS, VicGrid, ElectraNet, DataVic (compiled October 2026).

Real-to-apparent ratio. Modern data centres ~0.95; 1.0 for unity-PF. Sets the MVA the grid must carry (MVA = MW / PF).

Presets: 0.1 near-zero (CDC/Southgate) / 2 liquid-cooled / 10 cooling-tower air

Large industrial contract in Victoria: roughly 0.05-0.13 AUD/kWh
