Start Campus Data Hub (SIN01)
Status: Operational (First Building, SIN01) | Location: Sines, Portugal (Atlantic Coast)
Project Overview
The Start Campus Data Hub in Sines, Portugal, is one of the most ambitious and strategically significant data center developments in Europe, positioning Sines as a new, green digital gateway. Officially launching its first building, SIN01, in Q2 2025, the project is rapidly transitioning from a plan into an operational reality. The entire campus is planned as a Gigascale facility, ultimately targeting a monumental total power capacity of 1.2 GW across six dedicated buildings, driven by a total investment that is expected to approach €10 Billion over the life of the project.
This project's core differentiator is its profound commitment to sustainability and efficiency. Leveraging Portugal's already high share of renewable energy, the campus is designed to operate on 100% renewable energy from the national grid. Crucially, its location on the Atlantic coast allows it to utilize a sophisticated Seawater Cooling (SWAC) system. This highly efficient, closed-loop process significantly reduces the facility's reliance on fresh water and mechanical cooling, resulting in an exceptionally low and industry-leading PUE target of approximately 1.1. This makes it a model for sustainable, energy-intensive AI, HPC, and Cloud workloads.
Strategically, the Sines location is paramount. It is the landing point for several high-capacity submarine fiber-optic cables, including the 2Africa and BlueMed systems, making it an ideal, low-latency interconnection hub between Europe, the Americas, and Africa. The SIN01 building represents the initial phase, providing a first wave of critical capacity to anchor the campus and attract major Hyperscale operators looking for highly redundant (Tier IV-ready), sustainable digital infrastructure that is optimized for the power-hungry demands of Artificial Intelligence deployments.
