Data Centre Energy Infrastructure Portfolio

The Challenge

For large data centres, access to electricity is increasingly one of the most important development constraints. A site may have suitable land, telecommunications access and planning potential but still be commercially unviable if sufficient grid capacity cannot be secured within an acceptable timeframe. The core development question becomes: how much grid capacity is actually required, how much demand can be flexible, how much energy should be produced onsite, and how much storage is required to integrate those resources reliably.

OnyX’s Approach

• Develops data centre opportunities by combining energy infrastructure development with detailed load analysis.
• Assesses grid capacity, staged maximum demand, flexible-load capability, renewable generation potential, battery sizing and connection architecture as one integrated system.
• Designs the energy architecture so onsite renewable generation serves the data centre first, excess generation can charge the BESS, and storage can also utilise available flexible grid capacity when technically and commercially appropriate.
• Treats power availability as a core site-selection and investment variable from day one, rather than a constraint discovered after land acquisition.
• Assesses the broader infrastructure ecosystem required to make the opportunity investable: network capacity, load profile, renewable resource, redundancy philosophy, planning constraints and development pathway.

Flagship Concept

A flagship South Australian concept within the portfolio is being assessed around a maximum facility demand of approximately 40 MVA with staged load profiles and a target PUE of approximately 1.2. The energy system is being optimised around the interaction between firm grid supply, onsite renewable generation, battery storage and flexible demand.

Development Outcome

The Data Centre Portfolio represents the next evolution of OnyX’s development capability: applying experience across solar, BESS, grid connection, flexible energy assets and investor-led origination to high-value, energy-intensive infrastructure. The objective is to originate power-secure, energy-optimised and investment-ready data centre opportunities where electricity is treated as a core design input from the beginning.
