Overview
Start Campus operates the SINES Data Campus in Sines, Portugal, delivering AI-ready infrastructure for high-density workloads such as HPC and cloud. It provides powered-shell, turnkey and build-to-suit data-center solutions with global connectivity, using 100% renewable energy and seawater cooling on a repurposed power-station site to reach a PUE of 1.1 and a WUE of 0. Its master plan envisions up to 1.2 GW of capacity, with SIN01 live at 37.5 MW and SIN02 planned at 200 MW, and it pursues large GPU deployments through partnerships like its expanded collaboration with Nscale and Microsoft. The goal is to offer scalable, sustainable, AI-ready infrastructure and enable large-scale GPU compute deployments through strategic partnerships and rapid capacity expansion.
