• Power access and grid capacity are the main constraints on Europe’s data centre expansion
  • Regulatory complexity and skills shortages are delaying investment and deployment

What happened

Europe’s data centre market is expanding rapidly, fuelled by rising demand from artificial intelligence, cloud computing and digital services, according to Michael Winterson, secretary general of the European Data Centre Association (EUDCA).

In an interview with Capacity at Datacloud Energy Europe, Winterson said demand for capacity is increasingly outpacing supply, but growth is being constrained by limited access to power. Grid capacity shortages and long connection timelines are now the most significant barriers facing operators across Europe.

According to CBRE’s 2025 European Data Centre Outlook, power availability constraints have delayed approximately 1.2GW of planned capacity across major markets including London, Frankfurt, and Amsterdam. Grid connection timelines have stretched from 12-18 months to 3-5 years in some jurisdictions, forcing operators to reconsider expansion plans.

He also pointed to regulatory fragmentation and complex permitting processes as additional challenges slowing project development. According to Winterson, inconsistent rules across European markets are making it harder for investors to deploy capital efficiently, despite strong underlying demand.

The sector is also facing a shortage of skilled workers, particularly in engineering and construction roles, which is further limiting the pace of expansion.

Why it’s important

Data centres are a critical foundation for Europe’s digital economy, supporting cloud infrastructure, AI deployment and data-driven services. As demand continues to grow, constraints on energy and infrastructure risk undermining Europe’s competitiveness.

According to the original capacity report, the sector is expected to attract significant investment in the coming years, reflecting strong long-term demand. However, from a financial perspective, persistent bottlenecks could shift investment towards regions with faster deployment capabilities and more accessible energy.
