Summary Under the proposed Cloud and AI Development Act (CADA), Member States would have to ensure that the permit-granting procedure for data centre projects in designated acceleration zones does not exceed 12 months from the submission of a comprehensive application (Article 13(5)). It is a maximum ceiling, not a target: it is "without prejudice to any shorter time limits set by Member States." Where national law already has a "highest national significance" status, such projects must be allocated it — but CADA would not require Member States to create one. This is a proposal and is not yet law.
Detail
CADA (COM(2026) 502 final) introduces a framework to accelerate data centre capacity across the EU. A central tool is the data centre acceleration zone (Article 10) — an area a Member State designates where data centre deployment is facilitated through streamlined permitting. The timeline rule for those zones is in Article 13(5).
The 12-month ceiling
Article 13(5) provides that Member States "shall ensure that administrative applications related to the planning, construction and the operation of data centre deployed in acceleration zones are processed in an efficient, transparent and timely manner," and that:
"The permit-granting procedure for data centre projects deployed in data centre acceleration zones shall not exceed 12 months, from the moment a comprehensive application has been submitted."
This is a hard maximum on the administrative procedure, intended to remove indefinite delay and give investors timeline certainty. It is not a minimum.
What starts the clock: a "comprehensive application"
The 12 months run only "from the moment a comprehensive application has been submitted." Preliminary inquiries or expressions of interest do not start the clock. The proposal does not set out an exhaustive list of what a comprehensive application must contain — that detail would be governed by the relevant procedural rules and national implementation — so an incomplete dossier may not start, or may interrupt, the timeline depending on those rules. The single information point under Article 12 is intended to help operators reach a complete filing.
Interaction with national law
Article 13(5) states that the time limit "shall be without prejudice to any shorter time limits set by Member States." So 12 months is a ceiling, not a uniform mandate: if a Member State already guarantees a shorter procedure (say nine or ten months), that shorter limit stands. CADA would not require Member States to lengthen faster processes to 12 months.
"Highest national significance" status
Article 13(5) also provides that, "[w]here such a status exists in national law, data centre projects shall be allocated the status of highest national significance possible and be treated as such in permit-granting processes." Crucially, the same paragraph adds that "[t]his paragraph shall apply only where such status exists in national law and shall not create an obligation for Member States to introduce such status." Where the status exists, it can bring procedural advantages (such as prioritisation); where it does not, CADA does not force Member States to invent one.
How the baseline permit makes 12 months realistic
The 12-month cap works alongside the aggregated baseline permit in Article 13(2). For each acceleration zone, Member States prepare and issue this zone-level permit covering the permits and administrative authorisations commonly required for projects in the zone, excluding installation-specific permits. Because the generic environmental and planning conditions are cleared at zone level (Article 13(3)), an individual operator need only obtain additional permits for activities falling outside the baseline permit (Article 13(4)) — which is what makes a 12-month procedure for the project-specific approvals achievable.
Why it matters for the EU cloud ecosystem
The rationale is the EU's compute-capacity gap. The proposal's explanatory material notes that EU data centre deployment lags demand, particularly for the low-latency compute that AI workloads need, and that the aim is to triple EU data centre capacity within the next five to seven years and reach the needed capacity by 2035. Fragmented, lengthy permitting has been a major barrier. Capping the procedure at 12 months aims to reduce regulatory uncertainty, accelerate capacity roll-out, and prevent permitting delay from becoming a de facto barrier to entry.
What this means for you
If you are a cloud or data centre operator planning EU capacity, the 12-month cap would offer a clearer, more predictable environment. To prepare:
- Map acceleration zones. The cap applies only inside designated zones (Articles 10, 13(5)); your strategy differs sharply depending on whether a site is in or out.
- File comprehensive applications. The clock starts only on a comprehensive application. Build complete dossiers, and use the single information point (Article 12) to confirm completeness before filing.
- Leverage the baseline permit. Ask prospective host zones about the status of their aggregated baseline permit (Article 13(2)); a fully issued one smooths the path to the 12-month project permit.
- Check for "highest national significance" status. Where a Member State has such a category, your project in a zone should be allocated it — request the classification explicitly.
- Look for shorter national limits. Some Member States may offer faster tracks below 12 months (Article 13(5)).
Common misconceptions
"The 12-month limit applies to all EU data centre projects." No. It applies only to projects in designated acceleration zones (Article 13(5)); projects elsewhere stay on unharmonised national timelines.
"The clock starts when I file any document." No. It starts only on a comprehensive application; preliminary or incomplete filings do not trigger it.
"Member States must create a 'highest national significance' status." No. Article 13(5) applies only where such a status already exists in national law and creates no obligation to introduce one.
"The 12 months includes construction time." No. It covers only the permit-granting procedure (administrative approval), not building the facility.
"This rule is already in force." No. CADA is a proposal (COM(2026) 502 final), not yet adopted; the cap would apply only after the Regulation enters into force.
