Summary Under the proposed Cloud and AI Development Act (CADA), designating data centre acceleration zones would be conditionally mandatory for Member States. As proposed in Article 10(1), "where data centre capacity is being deployed within the territory of a Member State," that Member State "shall designate at least one data centre acceleration zone ... within its territory" by entry into force plus six months. There is no obligation to designate a zone in a Member State that is not deploying data centre capacity — but given the EU's stated aim to at least triple capacity by 2030, most Member States are likely to fall within the obligation. CADA is a proposal (COM(2026) 502 final), not yet in force.

Detail

CADA would introduce a harmonised framework to accelerate sustainable computing capacity across the EU. A central pillar is the "data centre acceleration zone," designed to streamline permitting, secure grid connectivity and promote energy efficiency.

The conditional obligation

The duty is tied to national deployment activity. Article 10(1) provides:

"Where data centre capacity is being deployed within the territory of a Member State, that Member State shall designate at least one data centre acceleration zone ('acceleration zone') within its territory by [P.O. insert the date of entry into force of this Regulation plus 6 months]."

This is a conditional mandatory requirement. If a Member State is deploying data centre capacity, it must designate at least one zone. If it is not, the specific Article 10 obligation does not trigger, because the premise ("where data centre capacity is being deployed") is not met. In practice, the EU's objective to at least triple capacity by 2030 makes it likely that most Member States will be caught.

Designation considerations

When designating zones, Member States must consider the aspects in Article 10(1)(a)–(h), including:

  • Site characteristics: location, dimension, and minimum/maximum facility sizes (Article 10(1)(a)).
  • Energy and connectivity: available and future power grid capacity, on-site storage and clean energy generation, and network connectivity capacity (Article 10(1)(b)–(c)).
  • Sustainability: a preference for reusing brownfield over greenfield sites, and the ability of the site to function sustainably by minimising environmental impact and supporting carbon-emission reduction (Article 10(1)(g)–(h)).
  • Permitting acceleration: measures taken to accelerate the granting of necessary permits within the zone (Article 10(1)(f)).

Under Article 10(2), where appropriate, Member States must also conduct (and review at least every three years) a comprehensive analysis of the energy needs and greenhouse-gas impacts of current and future zones, and ensure system operators' network development plans take it into account.

Timeline

The deadline is entry into force plus six months. The Regulation would enter into force on the twentieth day following its publication in the Official Journal (Article 48), so the six-month clock starts from that date. Compliance teams should track the publication date closely.

Conditions within zones

Once designated, Article 11(1) requires Member States to use the key performance indicators specified in Delegated Regulation (EU) 2024/1364 (adopted pursuant to Directive (EU) 2023/1791) when setting sustainability requirements for data centres in zones. Article 11(2) requires that resources within zones be allocated on fair, reasonable and non-discriminatory terms, with no speculative reservation or foreclosure that could impede effective competition.

Administrative support and permitting

Article 12 requires Member States to designate one or more single information points to assist operators with authorisations throughout the project lifecycle. Article 13 establishes facilitated processes, including an "aggregated baseline permit" for each zone covering commonly required authorisations (excluding installation-specific permits). The permit-granting procedure for data centre projects in zones must not exceed 12 months from submission of a comprehensive application (Article 13(5)).

What this means for you

For in-house counsel and compliance officers:

  1. Monitor national implementation. Track your Member State's progress in designating zones. If you plan to deploy in a jurisdiction that has not yet designated one, engage national authorities to understand whether your deployment triggers the obligation.
  2. Leverage zones. When selecting sites, prioritise designated acceleration zones for their 12-month permitting limit, single information points and aggregated baseline permits.
  3. Meet sustainability standards. Ensure projects in zones comply with the KPIs in Delegated Regulation (EU) 2024/1364; non-compliance could jeopardise accelerated permitting.
  4. Plan strategically. Aligning with the designation criteria (grid capacity, brownfield preference) supports compliance and may position a project for separate designation as a "data centre strategic project" under Article 14.

Common misconceptions

  • "All Member States must designate zones regardless of activity." No. The obligation is conditional on data centre capacity being deployed (Article 10(1)). If a Member State is not deploying capacity, the Article 10 duty does not trigger — though broader EU capacity targets may still drive deployment.
  • "Acceleration zones allow bypassing environmental assessments." No. Article 13(3) requires Member States to carry out all necessary procedures and assessments, including any relevant environmental assessments, at zone level before issuing the aggregated baseline permit. The aim is efficiency, not deregulation.
  • "Designating a zone guarantees immediate construction." No. Designation creates a framework for accelerated permitting. Operators still submit comprehensive applications and obtain installation-specific permits outside the baseline. The 12-month limit applies to processing applications, not to automatic approval.
