Colocation Facilities in European Union: Market Size, Businesses & Forecast 2026

The colocation facilities industry in the European Union provides secure physical space, electrical power, cooling infrastructure, and network connectivity for corporate and cloud-provider IT equipment. Driven by rapid digitalization and the widespread adoption of artificial intelligence applications, the industry is transitioning toward dense, hyperscale-adjacent infrastructure that requires massive amounts of electrical grid capacity. Official estimates from the International Energy Agency indicate that the energy consumption of data centres within the EU reached approximately 70 TWh in 2024 (International Energy Agency, 2025), emphasizing the sector's intensive infrastructure requirements

What does the Colocation Facilities in European Union industry cover?

Colocation facilities operate within the digital infrastructure sector, renting out physical real estate, power infrastructure, and cooling systems to multiple corporate tenants, cloud service providers, and telecommunication networks. Rather than managing applications or software, operators focus strictly on providing a highly resilient physical environment with redundant power supplies, backup generators, and fiber-optic cross-connects.

• •Facilities are structurally classified under the European NACE classification system within sections 62 and 63 for digital and information service infrastructure.
• •Infrastructure types range from regional enterprise retail colocation spaces to large-scale wholesale deployments that support hyperscale public cloud zones.
• •Energy footprints vary heavily by architecture, with typical facilities operating at power capacities between 5 MW and 100 MW or more.

Who operates in the industry and how is it structured?

The European colocation market features a mix of global real estate investment trusts (REITs), dedicated infrastructure funds, and regional providers. Operation is highly asset-intensive, requiring substantial upfront capital expenditure for land acquisition, high-voltage grid connections, and heavy industrial cooling infrastructure.

• •Geographic concentration remains dense in the historical 'FLAP-D' markets: Frankfurt, London, Amsterdam, Paris, and Dublin.
• •According to industry-tracked metrics published by European energy agencies, Germany represents the single largest consumer of European data centre power, accounting for approximately 21 TWh in 2024.
• •Secondary hubs, or Tier 2 markets, are expanding rapidly across Northern and Southern Europe due to local land availability and specialized regional connectivity lines.

What drives demand in the industry?

Demand for colocation space is primarily propelled by the exponential growth of enterprise data generation, corporate cloud migration, and the processing mandates of generative artificial intelligence. These factors force enterprises to outsource their internal server rooms to specialized, highly efficient third-party facilities.

• •Artificial intelligence workloads heavily accelerate power demand, with individual AI search queries consuming up to 10 times more electricity than traditional search queries according to European Parliament assessments.
• •National digitization mandates across the EU force public and private sector entities to migrate legacy IT infrastructure to modern, certified secure data centres.
• •Enterprise strategies are adopting hybrid IT models that blend on-premise cloud infrastructure with physical colocation footprints to optimize latency and sovereign data control.

Who are the notable companies in the industry?

The competitive landscape across the European Union is dominated by large, multinational digital infrastructure corporations capable of securing massive capital pipelines and institutional utility agreements. These entities compete directly on geographic footprint, connection density, and verified power availability.

• •Equinix, Inc. operates an extensive network of International Business Exchange (IBX) data centres across major European metro areas.
• •Digital Realty Trust, Inc., through its significant global platform and strategic acquisitions like Interxion, controls a massive share of carrier-neutral colocation space in Europe.
• •Keppel DC REIT, a publicly listed real estate investment trust, holds a specialized portfolio of high-grade data centre properties in key EU markets including Germany, Ireland, and the Netherlands.
• •Tele Columbus AG and various global carriers maintain dedicated colocation and meet-me-room assets integrated with their primary telecommunication fiber networks across the continent.

What are the recent trends and outlook?

The colocation industry is experiencing acute pressure regarding power grid capacity, leading operators to innovate in liquid cooling technologies and energy storage systems. Growth is increasingly directed toward regions that offer robust, direct access to renewable energy generation or advanced district heating networks.

• •The average Power Usage Effectiveness (PUE) for existing European facilities hovered around 1.6 in 2023, while modern state-of-the-art facilities routinely target designs below 1.3.
• •Projections by the International Energy Agency indicate EU data centre energy demand will rise from 70 TWh in 2024 to approximately 115 TWh by 2030.
• •Local grid constraints have caused localized development pauses or stringent grid-allocation policies in major hubs like Dublin, Ireland, and Amsterdam, Netherlands.

How is the industry regulated?

Regulatory scrutiny on the colocation industry has intensified substantially within the European Union, focusing squarely on environmental sustainability, carbon footprints, and energy efficiency. Compliance is no longer voluntary, as new directives mandate comprehensive reporting on utility usage and efficiency metrics.

• •The recast EU Energy Efficiency Directive explicitly requires data centre operators to publicly monitor and report their annual energy performance, water footprint, and renewable energy usage.
• •Under national implementations like the German Energy Efficiency Act, existing data centres must achieve a strict PUE of 1.5 by July 2027 and 1.3 by 2030, while new facilities from 2026 onward must hit 1.2.
• •The European Commission's upcoming data centre energy efficiency initiatives include the formalization of a sustainability labeling scheme to categorize facilities across member states.
