Summary As proposed in the Cloud and AI Development Act (CADA), a Member State that is deploying data centre capacity would have to designate at least one data centre acceleration zone within its territory, by six months after the Regulation enters into force (Article 10(1)). Designation is not automatic: when designating, Member States "shall consider" eight aspects in Article 10(1)(a)–(h), spanning site dimensions, grid and connectivity capacity, waste-heat reuse, a brownfield preference and overall sustainability. Designation then triggers further duties — energy-needs analysis feeding grid planning (Article 10(2)), inclusion in spatial plans with combined environmental assessments (Article 10(3)), and coordination among grid and network operators (Article 10(4)). CADA is a proposal and not yet in force, so this is what would apply if it is adopted.

Detail

CADA's supply-side answer to the EU's compute shortage is the data centre acceleration zone (the proposal's shorthand: "acceleration zone"), introduced in Title III, Chapter I. A zone is a designated area where the development, expansion and modernisation of data centres would be facilitated through streamlined regulatory and administrative procedures.

The obligation and the deadline

The duty falls on Member States. Under Article 10(1), "[w]here 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, in the draft's placeholder wording, "[P.O. insert the date of entry into force of this Regulation plus 6 months]" — six months after entry into force.

The obligation is conditional on activity. It applies "where data centre capacity is being deployed", so a Member State with no current or planned deployment would not be immediately required to designate a zone — though CADA's broader purpose is to stimulate deployment across the Union to close the capacity gap.

The eight aspects to consider

Designation is not a box-tick. Article 10(1) provides that Member States "shall consider the following aspects when designating acceleration zones". The eight aspects:

  1. Site location and dimension (a) — the location and dimension of the site or area, and the minimum and maximum size of facilities that could be built there.
  2. Power grid capacity and clean energy (b) — available and future power grid capacity, and the possibility and conditions for on-site storage and clean energy generation.
  3. Network connectivity (c) — available and future network connectivity capacity.
  4. Legacy copper networks (d) — the capacity of the zone to support the phasing out of legacy copper networks.
  5. Waste heat reuse (e) — available and future facilities that can reuse data centre waste heat.
  6. Permitting acceleration measures (f) — "all the measures taken to accelerate the granting of the necessary permits for constructing and operating data centres within the given zone", linking designation to the administrative reforms in Articles 12 and 13.
  7. Brownfield preference (g) — "the preference for reusing brownfield sites over using greenfield sites".
  8. Sustainability and climate resilience (h) — "the ability of the site or area to function sustainably, particularly as regards preventing or minimising environmental impacts and supporting the reduction of carbon emissions and its climate resilience".

After designation: energy planning and grid integration

Article 10(2) sets out steps Member States would take "where appropriate to facilitate the development of acceleration zones". Under point (a), they would 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 identify the energy-infrastructure capacity required; this analysis would be carried out at least when the zones are designated. Under point (b), they would ensure that the network development plans prepared by transmission system operators (under Article 51 of Directive (EU) 2019/944) and distribution system operators (under Article 32 of the same Directive) take due account of that analysis, considering the potential of anticipatory investments to accommodate future system needs.

Spatial planning and combined assessments

Article 10(3) asks national, regional and local authorities responsible for spatial and development plans to consider including provisions for data centre projects in zones and the necessary infrastructure, and requires Member States to ensure that relevant spatial planning data are available to operators. Where such plans are subject to assessment under the Strategic Environmental Assessment Directive (Directive 2001/42/EC) and Article 6 of the Habitats Directive (Directive 92/43/EEC), those assessments "shall be combined"; where applicable, the combined assessment would also address the impact on water bodies referred to in the Water Framework Directive (Directive 2000/60/EC).

Coordination among authorities and operators

Article 10(4) requires that, when designating zones, Member States ensure the involvement of and coordination among all relevant national, regional and local authorities and entities — including electronic communications network operators (Directive (EU) 2018/1972), transmission system operators and distribution system operators (Directive (EU) 2019/944). This multi-stakeholder design is meant to break the siloed decision-making that delays grid, connectivity and land-use approvals.

What this means for you

For public-sector officers, designation reshapes how digital infrastructure is planned and procured.

1. Plan proactively across agencies. Data centre deployment is not a standalone IT issue. Because designation turns on grid capacity, connectivity and spatial planning (Article 10(1)(a)–(c)), you should engage energy regulators, telecom operators and planning departments early, and may support the energy-needs analysis under Article 10(2).

2. Prioritise sustainable siting. The brownfield preference (Article 10(1)(g)) and waste-heat reuse (Article 10(1)(e)) are likely to become evaluation criteria; procurement may need evidence that a provider's facilities sit in zones meeting these benchmarks.

3. Use the streamlined track. Once a zone is designated, deployment should be faster thanks to the aggregated baseline permit and single information points in Articles 12 and 13.

4. Expect ongoing monitoring. The three-year energy-needs review cycle (Article 10(2)) implies recurring reporting on grid integration and environmental impact.

Common misconceptions

"All data centres must be in acceleration zones." No. Article 10(1) requires Member States to designate zones where capacity is being deployed; it does not require every data centre to sit in one. Facilities outside a zone may still be built, but without the streamlined permitting and coordinated planning the zone framework provides.

"Designation is a one-time event." No. It begins an ongoing process: Article 10(2) requires an energy-needs review at least every three years, spatial plans are updated, and the zone's performance is monitored.

"Brownfield preference bans greenfield sites." No. Article 10(1)(g) states a "preference" for brownfield over greenfield; it does not prohibit greenfield, though greenfield choices are likely to face more scrutiny.

"Designation automatically solves grid constraints." No. Article 10(1)(b) and 10(2) require grid capacity to be considered and aligned with planning, but the physical grid upgrade remains a separate, coordinated investment for transmission and distribution system operators.
