Tungkillo Compute and Energy Hub

The Tungkillo Compute and Energy Hub, proposed by Quantum DC at 312 Collins Road, Tungkillo, South Australia, is a significant development aimed at supporting the region's digital future. This hyperscale data center will have a capacity of approximately 1,200 MW and will be powered by a combination of contracted renewable energy (wind and solar) and on-site gas-fired generation. The project includes the construction of two new substations and electrical infrastructure connecting to the existing ElectraNet 275 kV transmission line. The hub is designed to add new energy supply to South Australia's electricity system, with on-site generation capable of supplying electricity to the grid at times. The data center will utilize closed-loop, direct-to-chip liquid cooling, minimizing water usage. Water for operations will primarily come from harvested rainwater, supplemented by commercial water carriers. The project is planned in three stages, with Stage 1 expected to commence operations in 2028 and full completion by 2031. Environmental impacts will undergo comprehensive assessment, and Quantum DC is committed to early and open community engagement throughout the planning process.
