Summary As proposed in the Cloud and AI Development Act (CADA), data centre acceleration zones are areas designated by Member States in which the development, expansion and modernisation of data centres would be facilitated through streamlined planning, permitting and grid-coordination procedures. Under Article 10, a Member State that is deploying data centre capacity would have to designate at least one such zone within its territory by six months after the Regulation enters into force, weighing eight specific aspects (site, energy, connectivity, sustainability and more). They sit in Title III, Chapter I of the proposal and are designed to help close the EU's compute-capacity gap while keeping deployment aligned with Union energy-efficiency and environmental law. CADA is a Commission proposal (COM(2026) 502 final) and is not yet in force, so everything described here would only take effect if it is adopted.
Detail
Title III of CADA, "Data centre capacities", opens with Chapter I on data centre acceleration zones. The chapter's anchor is Article 10, "Designation of data centre acceleration zones". Acceleration zones are not a marketing label: they would be legally designated areas in which Member States commit to removing the planning, permitting and infrastructure bottlenecks that today slow data centre construction.
The core obligation and deadline
Under Article 10(1), where data centre capacity is being deployed within the territory of a Member State, that Member State would have to designate at least one data centre acceleration zone (the proposal's shorthand is simply "acceleration zone") within its territory by, in the words of the draft, "[P.O. insert the date of entry into force of this Regulation plus 6 months]" — that is, six months after entry into force. The obligation is conditional on activity: it is triggered "where data centre capacity is being deployed", so a Member State with no deployment under way would not be immediately bound, even though the proposal's wider aim is to stimulate deployment across the Union.
The purpose, as set out in the recitals, is that these zones "should contribute to this objective by enabling infrastructure deployment at scale and speed within a clear and streamlined regulatory framework", helping to address the Union capacity gap and to increase the Union's "competitiveness, autonomy and technological resilience, while ensuring compliance with applicable Union law".
The eight aspects to consider when designating a zone
Article 10(1) provides that Member States "shall consider the following aspects when designating acceleration zones":
- 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.
- Power and clean energy (b) — available and future power grid capacity, and the possibility and conditions for on-site storage and clean energy generation.
- Network connectivity (c) — available and future network connectivity capacity.
- Legacy copper networks (d) — the capacity of the zone to support the phasing out of legacy copper networks.
- Waste heat (e) — available and future facilities that can reuse data centre waste heat.
- Permitting measures (f) — all measures taken to accelerate the granting of the necessary permits for constructing and operating data centres within the zone.
- Brownfield preference (g) — a preference for reusing brownfield sites over using greenfield sites.
- Sustainability and climate resilience (h) — the ability of the site to function sustainably, particularly as regards preventing or minimising environmental impacts and supporting the reduction of carbon emissions and its climate resilience.
Energy analysis and grid planning
Article 10(2) adds duties that would apply "where appropriate to facilitate the development of acceleration zones". Member States would, under point (a), conduct — and review at least every three years — a comprehensive analysis of the energy needs of current and future zones and their respective impacts on greenhouse gas emissions, identifying the energy-infrastructure capacity needed for data centre projects there; this analysis would be carried out at least when the zones are designated. Under point (b), Member States would ensure that the network development plans prepared by transmission and distribution system operators under Directive (EU) 2019/944 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 acceleration zones and the necessary infrastructure, and requires Member States to ensure that relevant spatial planning data are available to data centre 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 would 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).
Multi-stakeholder coordination
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) and transmission and distribution system operators (Directive (EU) 2019/944). This is designed to prevent the siloed decision-making that often delays grid connections and environmental sign-off.
How the zone connects to the rest of Chapter I
Article 10 does not stand alone. Article 11 sets the conditions inside a zone: sustainability requirements built on the key performance indicators in Delegated Regulation (EU) 2024/1364 (adopted under the Energy Efficiency Directive, Directive (EU) 2023/1791), and an obligation that resources be allocated on fair, reasonable and non-discriminatory terms without speculative reservation or foreclosure. Article 12 would give operators a right to be assisted by a single information point across the project lifecycle. Article 13 would treat projects in zones as strategic projects under the forthcoming Regulation on speeding-up environmental assessments, have Member States issue an aggregated baseline permit per zone, and cap permitting at 12 months from a comprehensive application. Together these provisions trade faster deployment for verifiable sustainability and fair competition.
What this means for you
If you work in or buy from the public sector, acceleration zones would change how digital infrastructure is planned and procured.
- Strategic planning. If your authority handles spatial planning, grid management or economic development, expect to be part of identifying and designating zones, in close coordination with energy and network operators (Article 10(4)).
- Permitting efficiency. Projects sited in a designated zone should benefit from the aggregated baseline permit and the 12-month permitting cap that Article 13 would introduce — useful when timelines for public cloud or AI infrastructure matter.
- Sustainability compliance. Deployment in a zone would be tied to the KPIs in Delegated Regulation (EU) 2024/1364 (Article 11(1)); favour projects that can evidence energy efficiency, waste-heat reuse and clean-energy integration.
- Data availability. Article 10(3) would require relevant spatial planning data to be made available to operators — useful for attracting investment to your region.
- Coordination. Open clear channels with grid operators and the relevant authorities early; the model depends on it.
Common misconceptions
- "Acceleration zones bypass environmental rules." No. The aim is to combine and accelerate assessments, not eliminate them. Article 10(1)(h) requires the site to be able to function sustainably, Article 10(3) requires combined SEA/Habitats assessments, and Article 11(1) imposes KPI-based sustainability requirements.
- "Any data centre can be built in a zone." Deployment would be conditioned on the sustainability requirements set under Article 11(1), and Article 11(2) prohibits speculative reservation and foreclosure.
- "Zones are only for new builds." Recital 38 frames zones as places where "the development, expansion and modernisation of data centres may be facilitated" — modernisation and expansion of existing sites are included.
- "A Member State with no data centres must still designate a zone." The Article 10(1) obligation is triggered "where data centre capacity is being deployed"; it tracks deployment activity rather than the mere existence of infrastructure.
