Summary Under the proposed Cloud and AI Development Act (CADA), a "data centre" is not defined by new, bespoke rules within the text itself. Instead, Article 2(10) of the proposal explicitly imports the existing definition from point 2.6.3.1.16 of Annex A to Regulation (EC) No 1099/2008. This means a data centre is legally understood as a facility used for housing computer systems and associated components, such as telecommunications and storage systems. For public-sector procurement officers and infrastructure planners, this definition is the critical gateway: it determines whether a project falls under Title III of CADA, triggering accelerated permitting in data centre acceleration zones, eligibility for strategic project designation, and mandatory sustainability reporting based on Delegated Regulation (EU) 2024/1364.

Detail

To understand what constitutes a data centre under CADA, one must look beyond the Cloud and AI Development Act itself and trace the definition to its source in broader EU energy legislation. CADA is designed to accelerate the deployment of computing infrastructure to meet the growing demands of AI, but it relies on established technical definitions to ensure legal consistency across the EU's regulatory landscape.

The Legal Definition: Article 2(10)

The primary anchor for this concept is Article 2(10) of the CADA proposal. The text states:

"β€˜data centre’ means data centre as defined in point 2.6.3.1.16 of Annex A to Regulation (EC) No 1099/2008 of the European Parliament and of the Council;"

Regulation (EC) No 1099/2008 concerns statistics on energy production and consumption. By referencing this specific point, CADA adopts a definition focused on the functional and physical characteristics of the facility. While CADA does not reproduce the full text of the 1099/2008 definition, the referenced definition generally describes a data centre as a facility used for housing computer systems and associated components, such as telecommunications and storage systems.

This importation of the definition is crucial because it ties CADA's cloud and AI ambitions directly to existing energy efficiency frameworks. It ensures that when CADA mandates sustainability reporting or energy efficiency standards, it is speaking the same language as the Energy Efficiency Directive and existing statistical frameworks. It prevents regulatory fragmentation by ensuring that a "data centre" in CADA is the same entity as a "data centre" in EU energy statistics.

Scope and Application in Title III

Once a facility is classified as a "data centre" under this definition, it becomes subject to the specific obligations and opportunities outlined in Title III of CADA, which focuses on "Data Centre Capacities." The definition is the gateway to several key mechanisms:

  1. Data Centre Acceleration Zones (Article 10): Member States are required to designate specific geographic areas as "acceleration zones" where data centre capacity is being deployed. Article 10(1) mandates that Member States designate at least one such zone where they are deploying data centre capacity. If your infrastructure qualifies as a data centre under the Article 2 definition, it may be eligible for placement in these zones. Being in an acceleration zone triggers streamlined permitting processes and access to single information points.
  2. Strategic Project Designation (Article 14): Large-scale data centre projects can be designated as "strategic projects" by the Commission. Article 14 allows for this designation if the project meets specific criteria, such as enhancing essential public sector functions, including highly sustainable or innovative features, or addressing major shortages in compute capacity. The definition in Article 2 determines whether a proposed facility is even eligible to apply for this status.
  3. Single Information Points (Article 12): For data centre operators deploying projects in acceleration zones, Member States must designate single information points to assist with authorisations. The applicability of this support service hinges on the project being a "data centre project" as defined by the overarching definition.
  4. Monitoring the Capacity Gap (Article 15): The Commission is tasked with monitoring the compute capacity available in the Union. This monitoring relies on the consistent application of the Article 2 definition to accurately measure the "volume of demand for data centre capacity" and the "size of the capacity gap."

The Role of the "Data Centre Operator"

While Article 2(10) defines the facility, it is important to distinguish the facility from the entity operating it. Article 2(11) defines a "data centre operator" by referencing Article 2, point (7), of Delegated Regulation (EU) 2024/1364. This distinction is vital for procurement officers: the data centre is the asset; the data centre operator is the legal entity responsible for its compliance with CADA's sustainability and permitting rules. When procuring services or land for infrastructure, you are engaging with the operator, but the regulatory obligations attach to the data centre itself.

Why This Definition Matters for Procurement and Planning

For public-sector bodies, the definition dictates the regulatory path for infrastructure projects. If a proposed facility meets the definition of a data centre, it is not just a real estate transaction; it is a strategic digital infrastructure project. This triggers:

  • Accelerated Permitting: Under Article 13, permit-granting procedures for data centres in acceleration zones must not exceed 12 months from the moment a comprehensive application has been submitted. This is a significant reduction compared to standard administrative timelines.
  • Sustainability Requirements: Article 11 requires that sustainability requirements for data centres deployed in acceleration zones use the key performance indicators (KPIs) specified in Delegated Regulation (EU) 2024/1364. These KPIs cover metrics such as Power Usage Effectiveness (PUE) and Carbon Usage Effectiveness (CUE).
  • Grid and Energy Planning: Article 10(2) requires Member States to conduct a comprehensive analysis of the energy needs of acceleration zones. Your project's classification as a data centre means it must be factored into national grid planning and anticipatory energy investments to ensure sufficient power supply.
  • Non-Speculative Use: Article 11(2) mandates that the allocation and use of resources within acceleration zones must not give rise to speculative reservation or foreclosure practices. The definition ensures that only genuine data centre projects benefit from these zones.

What this means for you

For public-sector procurement officers, infrastructure planners, and data centre developers, understanding the definition of a data centre under CADA is the first step in leveraging the Act's benefits.

  • Verify Eligibility: Before launching a tender for new computing infrastructure, confirm that the facility meets the definition in Regulation (EC) No 1099/2008. If it is a small server room within a general office building, it may not qualify as a standalone "data centre" for the purposes of Title III. However, if it is a dedicated facility for housing computer systems and telecommunications components, it does.
  • Leverage Acceleration Zones: If you are planning a large-scale deployment, check if your region has designated a data centre acceleration zone under Article 10. If not, engage with national authorities to understand the timeline for designation. Deploying in an acceleration zone grants access to single information points (Article 12) and capped permitting timelines (Article 13).
  • Plan for Energy and Sustainability: Because the definition links to energy regulations, ensure your procurement specifications align with the sustainability key performance indicators (KPIs) mandated by Article 11 and Delegated Regulation (EU) 2024/1364. You cannot treat energy efficiency as an optional extra; it is a core requirement for data centres in acceleration zones.
  • Engage with Operators: When drafting contracts, clearly define the roles of the "data centre operator" (Article 2(11)). Ensure that the operator is contractually bound to provide the necessary data for energy needs analysis (Article 10(2)) and to comply with the non-speculative reservation of resources (Article 11(2)).

Common misconceptions

Misconception 1: CADA creates a new, unique definition of a data centre. Many assume that because CADA is a new law, it defines "data centre" from scratch. In reality, Article 2(10) explicitly imports the definition from Regulation (EC) No 1099/2008. This means the definition is already established in EU law, and CADA simply applies it to the cloud and AI context.

Misconception 2: Any server room is a data centre under CADA. The definition refers to facilities used for housing computer systems and associated components. Small, localized IT closets within municipal buildings typically do not meet the scale or functional independence implied by the regulatory framework of Title III. CADA targets large-scale infrastructure deployments that impact grid capacity and national compute strategy.

Misconception 3: The definition only matters for construction permits. The definition is the key to the entire Title III framework. It determines eligibility for strategic project status (Article 14), access to single information points (Article 12), and mandatory sustainability reporting (Article 11). It is not just a construction term; it is a regulatory classification that dictates the lifecycle management of the asset.
