Global annual data center construction investment is projected to surpass $1 trillion by 2027, effectively doubling market spending compared to 2024 levels, according to a report published by Allianz Commercial. The analysis highlights that Spain, alongside select European peers, is poised for an accelerated rollout as artificial intelligence demand transforms traditional server farms into mission-critical physical infrastructure.
The report, titled El boom de la construcción de centros de datos: tendencias de riesgos y siniestros, details how capital deployment extends far beyond standard server rooms. Spending encompasses electrical power generation, grid transmission upgrades, advanced cooling systems, high-speed telecommunications infrastructure, and semiconductor manufacturing. While the United States and China are expected to account for roughly 62% of all new global capacity additions through 2030, analysts note that subsequent waves of capital allocation will become increasingly international.
Within Europe, traditional core hubs like Germany, the United Kingdom, and Ireland remain dominant, but researchers emphasize that Spain, Finland, and Denmark are experiencing rapid expansion due to relatively favorable energy availability and streamlined permitting conditions. Meanwhile, across the Asia-Pacific region excluding China, installed capacity is projected to surge from approximately 9 gigawatts to more than 28 gigawatts by 2030, led by exceptional growth in markets such as Malaysia.
Spain’s Rapid Ascent as a Southern European Digital Hub
According to industry metrics cited by Allianz Commercial from the Spanish Data Center Association (SpainDC), total commercial IT power capacity reached 439 megawatts at the close of 2025, marking a 24% increase over the previous year. Current industry trajectories suggest national capacity could climb to 2,537 megawatts by 2030.
SpainDC projections indicate cumulative national investments could reach 66.900 million euros by the end of the decade, contributing an estimated 7.300 million euros annually to the national gross domestic product. This rapid scaling cements the country’s status as a primary digital gateway for Southern Europe, though it also intensifies structural exposure to construction delays, power grid constraints, and climate vulnerabilities.
“La IA está convirtiendo la última generación de centros de datos, que deja de ser un activo inmobiliario especializado, en una infraestructura crítica,” stated Thomas Lillelund, CEO of Allianz Commercial, emphasizing that operational continuity now outweighs traditional real estate considerations.
Lillelund noted that structural success relies heavily on robust risk mitigation frameworks. “La magnitud de la inversión es extraordinaria, a medida que estos centros evolucionan desde el almacenamiento tradicional de datos hacia necesidades de computación de alto rendimiento, pero el éxito dependerá cada vez más de la resiliencia: acceso a energía, cadenas de suministro fiables, sólidos controles de construcción, así como una selección de emplazamientos que tenga en cuenta el clima y programas de seguros que reflejen el verdadero riesgo de acumulación,” he explained.
Physical Bottlenecks and Climate Vulnerability
Market expansion is increasingly constrained by physical bottlenecks rather than financial limitations. Sector analysts report that competitive advantage depends primarily on securing stable electricity supplies, high-capacity grid connections, specialized engineering equipment, and qualified technical labor.
Furthermore, climate resilience has emerged as a critical underwriting concern. Global data center assets face substantial environmental exposure: roughly 79% of global capacity sits within regions highly vulnerable to natural catastrophes, while 54% faces chronic heat stress and drought conditions that complicate thermal management and water-intensive cooling operations.
Insurance markets are adapting rapidly to these complex operational risk profiles. The global insurance market dedicated to data center coverage is projected to more than double, growing from approximately 11.000 million dollars (unos 9.530 millones de euros, al cambio actual) to over 24.000 million dollars (cerca de 20.800 millones de euros) by 2030. Insurance demand is shifting away from isolated property damage policies toward comprehensive enterprise solutions spanning construction engineering, business interruption, cyber liability, and energy resilience.
Historical claims data underscores the evolving risk landscape. Allianz Commercial reports that fire represents the single greatest driver of loss severity, accounting for over half of roughly 700 million euros in analyzed insurance claims. Natural catastrophe losses, malicious acts including cyber incidents, and electrical failures follow closely as primary loss factors, while water damage and equipment breakdowns remain the most frequent operational claims.
