Firmus Southgate: 36,800 GPU Renewable AI Factory

Status: Operational / Phase 1B Deployment (April 2026)   |   Location: Repurposed Industrial Site, Launceston

Project Overview

Project Southgate in Tasmania represents a step-change in how high-performance AI infrastructure is conceived, positioning itself as a global benchmark for “Green AI” as of April 2026. Rather than retrofitting legacy data center designs, the project has been engineered from “silicon to grid,” tightly integrating compute architecture with energy supply and cooling systems. At its core is the proprietary Firmus Hypercube, a modular, liquid-cooled compute unit optimized for extreme density and efficiency, enabling the deployment of 36,800 NVIDIA GB300 GPUs within a highly compact footprint. This design supports the growing demand for large-scale AI training and inference while minimizing energy loss and thermal inefficiencies. A defining feature of Southgate is its power model: the facility runs on 100% firmed renewable energy sourced from Tasmania’s abundant hydro resources, complemented by wind and solar generation to ensure consistent, dispatchable supply. In March 2026, Firmus secured a multi-billion dollar agreement with a global hyperscaler for 18,400 GPUs, underscoring strong market demand for sustainable AI capacity. The site also achieves exceptional water efficiency, using approximately 99% less water than conventional data centers, a critical advantage in environmentally constrained regions. Collectively, these attributes position Project Southgate as a leading example of scalable, low-impact AI infrastructure in the southern hemisphere.
