Quetta Data Centers, a project by Azora in collaboration with Core Tech Capital, is set to advance the landscape of edge and AI data centers with its latest ventures. Recently, construction commenced on their Tres Cantos data center in Madrid, doubling its capacity to 20 MW. Simultaneously, their inaugural project in Barcelona is gaining traction in Molins de Rei, both set to strengthen Quetta's presence in the data center arena.

Emphasising sustainability, Quetta is forging ahead with plans to construct six edge data centers across Spain and Portugal. The facilities are designed to incorporate closed-loop liquid cooling, with the goal of reducing water consumption and achieving efficient power usage (PUE) of under 1.15. The projects, backed by over €500 million in investment, aim to advance Quetta’s technological capabilities while maintaining environmental standards.

The Barcelona and Madrid expansions are set to elevate Quetta’s total capacity to 30 MW. This represents 50% of their overarching target of 60 MW, marking a step on their strategic roadmap. Since being unveiled by Azora in 2024, Quetta Data Centers has merged operational expertise with technology, embodying efficiency, resilience, and sustainability.

The digital economy's meteoric rise has fuelled an ever-growing demand for robust data infrastructure. The sector is rapidly evolving, driven by needs stemming from AI, gaming, augmented reality, and the Internet of Things. In response, Quetta’s AI-ready facilities are engineered for high connectivity and low latency, equipped to meet the diverse demands of modern digital workloads. Quetta states that its goals for the data centers are to:

  • Operate on 100% renewable energy.
  • Ensure no water consumption for an eco-friendly approach.
  • Promote uncompromised energy efficiency through innovative solutions.

As Santiago Olivares, a partner at Azora, underscores, there’s a significant opportunity in fostering sustainable local data infrastructure, championing assets that fuel economic and environmental advancement. Likewise, Paco González from Core Tech Capital highlights Quetta's commitment to developing a resilient network, offering flexibility and supporting a multitude of clients.

These initiatives position Quetta to support growing demand for AI and digital services while maintaining a focus on resilience and environmental standards.
