Spain Data Center Rack Market Size, Share - Growth Analysis Report and Forecast Trends 2026-2030

The Spain data center market encompasses facility infrastructure, colocation services, and the rack-level hardware ecosystem that supports enterprise and hyperscale computing workloads. In 2026, the market is estimated at approximately USD 7.74 billion, building on the prior-year base of USD 6.89 billion, with installed power capacity expected to grow from roughly 0.98 thousand MW in 2025 toward 1.36 thousand MW by 2030. The market is underpinned by a combination of domestic digitalization and its role as a connectivity hub for the Iberian Peninsula and broader Mediterranean region.

• •Market valued at ~USD 7.74 billion in 2026, growing at a CAGR of 8.94% toward 2034
• •Installed data center capacity projected to rise from ~0.98 thousand MW (2025) to 1.36 thousand MW (2030)
• •Approximately 63 operational colocation data centers currently serving enterprise and cloud tenants

The primary catalyst for market expansion is the accelerating adoption of cloud services and AI-driven workloads across Spanish enterprises, government agencies, and financial institutions. Spain's abundant renewable energy resources, particularly solar and wind, have made the country a focal point for green data center development, with the green segment alone projected to grow from USD 3.19 billion in 2024 to over USD 9.14 billion by 2030. Regulatory frameworks promoting data sovereignty, digital public services, and energy-efficient infrastructure further reinforce long-term investment pipelines.

• •Cloud migration and AI compute demand driving hyperscale and enterprise facility expansion
• •Green data center segment expected to reach ~USD 9.14 billion by 2030 from ~USD 3.19 billion in 2024
• •Data sovereignty regulations and EU digital strategy encouraging domestic infrastructure investment

Spain's data center footprint is concentrated in Madrid, Barcelona, and key interconnect nodes along the Mediterranean corridor, with these cities accounting for the majority of colocation and hyperscale capacity. The colocation segment is the fastest-growing sub-market, projected to expand at a CAGR of approximately 31.86% through 2030, reflecting robust demand from multi-cloud tenants and international operators seeking European landing points. Green and sustainable facility certifications are becoming a differentiator, with newer builds prioritizing PUE-optimized designs and renewable PPAs.

• •Colocation market expected to grow at ~31.86% CAGR from 2024 to 2030
• •Capacity concentrated in Madrid and Barcelona metropolitan areas with expanding secondary nodes
• •Green data center certification and PUE optimization increasingly critical for new facility approvals

Who are the notable companies in the industry?

The market exhibits a partially fragmented competitive structure with a mix of large integrated facility operators, regional specialists, and a growing cohort of hyperscale developers building proprietary capacity. The sector spans integrated providers that own both real estate and infrastructure assets alongside colocation-focused operators that lease space and power to enterprise tenants. Capacity is concentrated in major metropolitan zones, though investment is gradually dispersing toward secondary markets with lower land and energy costs.

• •Mix of integrated infrastructure owners and colocation specialists creates semi-fragmented market structure
• •Technology routes range from traditional raised-floor designs to modern modular and hyperscale block deployments
• •Geographic capacity is front-loaded in Madrid and Barcelona with emerging development in Andalusia and Valencia corridors

What are the recent trends and outlook?

Looking ahead, the convergence of AI training and inference workloads will significantly influence rack density requirements, pushing demand toward high-power-density configurations and liquid-cooling-ready infrastructure. Sustainability mandates from the EU and Spanish regulators will continue to shape facility design, procurement, and operational standards through the decade. The market is well-positioned for sustained above-average growth as Spain capitalizes on its renewable energy advantage, geographic connectivity, and role within the broader European digital single market.

• •AI and high-performance computing workloads driving demand for high-density rack configurations and advanced cooling
• •EU sustainability directives and Spanish energy regulations accelerating the transition to zero-carbon facilities
• •Market on track for continued multi-year expansion supported by hyperscale land acquisition and fiber investment
