Summary No. As proposed, CADA's 12-month permit limit would not override shorter national deadlines. Article 13(5) states that the 12-month maximum is "without prejudice to any shorter time limits set by Member States." So the 12-month period would function as a regulatory ceiling, not a uniform floor: if a Member State requires a faster permit-granting process for data centre projects in acceleration zones, that shorter national deadline would still apply. CADA is a proposal and not yet in force, so this is what would apply if adopted.

Detail

The proposed Cloud and AI Development Act (CADA) would introduce a harmonised framework to accelerate the deployment of data centres across the EU. A central element is the "data centre acceleration zone" (the proposal's shorthand: "acceleration zone"), where permitting would be streamlined. The relationship between the EU-level time limit and national deadlines is set out explicitly to avoid undercutting faster national regimes.

The 12-month ceiling Article 13(5) of the CADA proposal would set a maximum duration for the permit-granting procedure for data centre projects deployed in acceleration zones:

"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."

As proposed, this would provide a hard cap on how long a competent authority can take to process a comprehensive application, aiming to remove indefinite delays and give operators legal certainty.

Shorter national limits preserved The same paragraph contains a saving clause that preserves stricter national timelines:

"The time limit shall be without prejudice to any shorter time limits set by Member States."

This confirms that the 12-month period would be a maximum, not a minimum. Member States that already impose — or choose to impose — shorter deadlines for specific infrastructure or zones would keep them. If national law required a decision within, say, six months, that six-month limit would apply, and CADA's 12-month provision would not extend it.

Context: the aggregated baseline permit To support these timelines, Article 13(2) would require Member States to prepare and issue an "aggregated baseline permit" for each designated acceleration zone. As proposed, that permit would cover the permits and administrative authorisations required for data centre projects within the zone, excluding installation-specific permits. Article 13(3) provides that, before issuing it, Member States would carry out all necessary procedures and assessments, including any relevant environmental assessments and planning procedures applicable at zone level. Article 13(4) then provides that data centres in the zone would need additional permits only for activities falling outside the baseline permit — reducing the per-project burden and making it easier to meet both the 12-month ceiling and any shorter national limit.

Highest national significance status Article 13(5) also provides that, where 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." As proposed, this is conditional: it applies only where the status exists in national law and does not create an obligation for Member States to introduce one.

A layered timeline For in-house counsel and compliance officers, CADA would not create a single, uniform EU-wide deadline. It would create a layered environment:

  1. An EU ceiling. No Member State could lawfully let a permit process run beyond 12 months once a comprehensive application is submitted.
  2. Shorter national limits intact. Where a Member State has stricter rules (for example nine or six months), those rules would remain fully applicable and enforceable.

The result, as proposed, is that fast-track national regimes would not be slowed to an EU average, while slower regimes would be compelled to accelerate to the 12-month maximum.

What this means for you

For legal and compliance teams managing data centre deployments, the interplay between Article 13(5) and national law calls for careful timeline management.

1. Verify national deadlines first. Do not assume the 12-month limit governs your project. Before submitting, identify the national and regional rules applicable to the relevant acceleration zone. If the host Member State has a shorter statutory limit, your compliance calendar must align with that shorter period; missing it could carry consequences under national law regardless of CADA's 12-month maximum.

2. Prepare "comprehensive" applications early. The clock starts "from the moment a comprehensive application has been submitted." If your application is incomplete, the authority may treat the clock as not having started or request further information. Ensure spatial-planning, environmental and connectivity documentation is complete before submission.

3. Leverage the aggregated baseline permit. Check whether the zone has an issued aggregated baseline permit (Article 13(2)). If it does, you may need additional permits only for activities outside the baseline (Article 13(4)), reducing the scope of your permitting effort.

4. Pursue "highest national significance" where it exists. Where national law provides this status, Article 13(5) would have projects allocated it and treated accordingly. This will not override national law, but it often triggers expedited review.

5. Document everything. Given the potential for disputes over whether an application was "comprehensive" or whether a deadline was missed, keep rigorous records of submissions, acknowledgments and information requests. This will matter if you need to rely on Article 13(5) or challenge an unreasonable delay.

Common misconceptions

Misconception 1: The 12-month limit is a uniform EU-wide deadline. Reality: As proposed, it is a maximum ceiling. Member States with shorter deadlines are not required to extend them to 12 months; Article 13(5) preserves shorter national limits.

Misconception 2: CADA overrides national environmental-assessment timelines. Reality: CADA would work alongside other EU law. Article 13(1) provides that data centre projects in acceleration zones are considered strategic projects within the meaning of Article 14 of the proposed Regulation on speeding-up environmental assessments and would benefit from the toolbox in the Annex to that Regulation. The detailed timelines for environmental components remain governed by that framework and national implementation, and shorter national time limits are preserved.

Misconception 3: All data centre projects benefit from the 12-month limit. Reality: Article 13(5) applies to data centre projects deployed in data centre acceleration zones. Projects outside designated zones may be subject to different, potentially longer, timelines under national law.

Misconception 4: The "highest national significance" status is mandatory everywhere. Reality: Article 13(5) applies this status only where it exists in national law and does not require Member States to create one.
