Renewable Energy % by Facility
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 1.37 is improving year-on-year. Modern hyperscaler facilities target PUE <1.15.
PUE explained
PUE = Total facility power / IT equipment power. PUE 1.0 = perfect efficiency. 2.0 = 50% overhead losses.
