Nscale Global has agreed to invest €695m ($812.6m) in infrastructure at the Sines data centre campus in Portugal, extending its collaboration with Microsoft and Start Campus.
The investment consists of €230m ($270m) for shared infrastructure and €465m ($546m) for a second 200MW building at the Sines Data Campus.
Under the agreement, Nscale plans to supply more than 66,000 Nvidia Rubin graphics processing units (GPUs) to the site from late 2027.
The deployment will use Nvidia Vera Rubin NVL72 systems and follows an earlier rollout of more than 12,600 Nvidia Blackwell Ultra GPUs at the campus’s first building for Microsoft.
The expanded infrastructure is intended to provide AI compute capacity for Microsoft’s European customers.
Start Campus operates the Sines Data Campus, which is fully permitted for 1.2GW capacity.
The project is part of Nscale’s wider collaboration with Microsoft, which also covers deployments in Norway, the UK and the US.
According to the group, AI infrastructure demand is expected to rise through 2030, while supply is constrained by power availability and the development of new capacity.
The Sines site is positioned to meet this demand, with support from renewable energy usage and a design targeting a power usage effectiveness (PUE) of 1.1 and water usage effectiveness (WUE) of zero.
PUE measures how efficiently a data centre uses energy, while WUE measures how much water it uses per unit of computing power.
The expansion represents a significant AI infrastructure investment in Portugal and adds to data centre capacity growth in Europe.
Nscale CEO and founder Josh Payne said: “This partnership enables the deployment of next-generation AI compute at the scale and efficiency required for frontier workloads. Building on a proven foundation, the expanded deployment in Sines, Portugal creates one of the most advanced environments in Europe for high-density AI infrastructure.
“It also represents one of the largest AI infrastructure investments in Portugal’s history – and among the most significant in the EU – reflecting the surging demand we are seeing for Nscale’s services.”
