Energy
AI infrastructure requires substantial and reliable electricity. Australian data centres currently consume over 2% of grid power, but that share of consumption could rise to 11% by 2035, creating tension between data centre growth and the energy transition.

Sorted by PUE ascending (lower PUE = better efficiency). Renewable % colour: green ≥80%, amber ≥50%, red <50%. Faded bar = not publicly disclosed — hover for details.
Renewable Share by Region
Dashed line = NEM Q4 2025 average (51%). CY2024 annual figures.
Generation Mix by Region (CY2024)
Each bar shows % of total generation by fuel type. Battery excluded (not separately reported for CY2024 annual figures).
Energy Sustainability Context
ACT-based facilities operate on 100% renewable electricity due to the Territory's renewable energy policy. NSW and VIC facilities are transitioning.
Average PUE of 1.29 is improving year-on-year. Modern hyperscaler facilities target PUE <1.15.
Power Usage Effectiveness (PUE) explained
PUE = Total facility power ÷ IT equipment power. PUE 1.0 = perfect efficiency (all power goes to IT). 2.0 = 50% overhead losses to cooling, lighting, and power distribution.
Carbon Intensity by Grid
Approximate figures. Varies by time of day and season.
