The MERLIN Edged Bilbao-Arasur campus continues to expand as a strategically positioned digital infrastructure hub, connecting Spain and Portugal to major European markets and high-capacity transatlantic subsea cable routes.
Demand for the 118 MW campus is surging. The second facility is now ahead of schedule and fully committed at 48 MW of critical capacity, while the first facility, completed in January 2024, stands at 22 MW and is fully leased. Construction on a third building is already underway, with further expansion phases under consideration as the campus scales to meet long-term demand.
The Bilbao-Arasur campus is engineered to support high-density and rapidly evolving compute environments:
- Up to 400+ kW per rack with plug-and-play liquid cooling integration
- Up to 120+ kW per rack using advanced air cooling systems
- Portfolio design PUE of 1.15
This flexible architecture enables seamless transition from traditional enterprise workloads to next-generation AI training and inference environments, without requiring fundamental infrastructure redesign.
A defining feature of the campus is its waterless cooling architecture, powered by ThermalWorks.
The system eliminates ongoing water consumption, replacing evaporative cooling approaches with advanced thermal design. At scale, this approach is projected to save billions of gallons of water annually across Edged’s European portfolio, while maintaining high-performance cooling for dense AI workloads.
The Bilbao-Arasur campus operates on 100% renewable energy, reinforcing its role as a next-generation sustainable infrastructure platform.
Backup power systems across European campuses utilize Hydrotreated Vegetable Oil (HVO), a renewable biofuel that reduces carbon emissions by up to 90% compared to diesel. HVO provides reliable standby power with significantly lower lifecycle emissions while remaining fully compatible with Tier 4 Final generator systems.
This combination ensures resilient operations while reducing environmental impact across both primary and backup energy systems.
As AI workloads continue to grow in scale and complexity, the Bilbao-Arasur campus is emerging as a critical node in Europe’s digital infrastructure network.
With high-capacity connectivity, rapidly expanding build phases and fully committed existing capacity, the campus is positioned to support the next wave of AI-driven demand, delivering performance, efficiency and sustainability at scale.
