Summary Under the proposed Cloud and AI Development Act (CADA), transmission system operators (TSOs) and distribution system operators (DSOs) would transition from passive connection providers to active strategic partners in data centre deployment. As proposed in Article 10, Member States must ensure that grid operators integrate specific energy needs analyses from designated "data centre acceleration zones" into their national network development plans. This mandates "anticipatory investments" to accommodate future compute demand. Furthermore, Article 10(4) explicitly requires the involvement of TSOs and DSOs in the coordination process when Member States designate these zones, ensuring that grid availability is a decisive factor in site selection before a zone is officially established.

Detail

The proposed Cloud and AI Development Act (CADA), COM(2026) 502 final, identifies the availability of reliable, high-capacity electricity as a critical bottleneck for the EU's ambition to triple its data centre capacity. To address this, the proposal establishes a framework where grid operators are not merely reactive entities processing connection requests, but proactive participants in the strategic planning of compute infrastructure. This shift is primarily governed by Article 10, which sets out the rules for the designation and operation of "data centre acceleration zones."

Mandatory Integration into Network Development Plans

The most significant operational obligation for grid operators under the proposal is found in Article 10(2)(b). This provision mandates that Member States must ensure their transmission system operators (TSOs) and distribution system operators (DSOs) take "due account" of specific energy analyses in their network development plans.

The process begins with a comprehensive analysis required by Article 10(2)(a). Before or when designating an acceleration zone, Member States must conduct an analysis of the current and future energy needs of that zone, including the impacts on greenhouse gas emissions. This analysis must identify the required energy infrastructure capacity necessary for the proper functioning of data centre projects located within the zone.

Article 10(2)(b) then creates a binding link between this analysis and grid planning. It requires that the network development plans prepared by TSOs (pursuant to Article 51 of Directive (EU) 2019/944) and DSOs (pursuant to Article 32 of Directive (EU) 2019/944) must "take due account of the analysis prepared pursuant to point (a) of this paragraph." The explicit purpose of this requirement is to facilitate "anticipatory investments" to accommodate future system needs.

This mechanism fundamentally alters the traditional timeline of infrastructure development. Instead of a reactive model where grid upgrades are requested only after a data centre project is fully designed and ready to connect, CADA as proposed would require grid capacity to be planned in parallel with, or ahead of, data centre construction. This aims to prevent the "grid connection queues" that currently delay projects, ensuring that the physical infrastructure is ready when the data centre is ready to operate.

Involvement in Zone Designation and Coordination

Grid operators are not just involved in the planning phase; they are embedded in the initial designation process of acceleration zones. Article 10(4) requires that when designating acceleration zones, Member States must ensure the "involvement of and coordination among all relevant national, regional and local authorities and entities."

This list of required entities explicitly includes:

  • "transmission system operators as defined in Article 2, point (35), of Directive (EU) 2019/944"
  • "distribution system operators as defined in Article 2, point (29), of Directive (EU) 2019/944"

This requirement ensures that grid constraints are considered at the earliest stage of site selection. A zone cannot be designated without the input of the entities responsible for delivering power to it. This coordination is critical because Article 10(1)(b) already requires Member States to consider "the available and future power grid capacity" when designating a zone. By involving TSOs and DSOs in the coordination process under Article 10(4), the proposal aims to prevent the designation of zones where grid capacity is physically or economically unattainable. This reduces the risk of "stranded assets" or prolonged connection delays that could undermine the investment case for data centres in those zones.

Strategic Planning and Anticipatory Investment

The interaction between data centre planning and grid planning is further reinforced by the requirement for ongoing reviews. Article 10(2)(a) requires Member States to conduct and review the energy needs analysis for acceleration zones at least every three years. Because TSOs and DSOs must incorporate these findings into their network development plans, grid operators are effectively locked into a cycle of continuous capacity assessment aligned with the EU's compute goals.

This mechanism supports the proposal's broader objective to triple EU data centre capacity within five to seven years. By legally binding grid operators to account for acceleration zone demands in their long-term network plans, CADA attempts to decouple data centre permitting timelines from grid connection queues. The proposal acknowledges in Recital 38 that "reliable and accurate information on future energy demand contributes to cost-effective grid development." The mandatory integration of zone-specific data into network plans is the legislative tool designed to provide that accuracy.

Distinction from Grid Connection Procedures

It is important to distinguish the strategic planning role of grid operators from the operational connection process. While Article 10 focuses on high-level planning and zone designation, Recital 38 notes that Member States should "facilitate clear and efficient procedures for grid connection and flexible connection agreements."

The proposal leverages existing EU electricity market rules (Directive (EU) 2019/944) for the technical aspects of connection but uses CADA to ensure that the planning for those connections happens at a macro level, well before individual data centre applications are submitted. The goal is to ensure that when a data centre operator applies for a connection in an acceleration zone, the grid capacity has already been accounted for in the TSO/DSO's strategic plan, rather than being a surprise bottleneck discovered during the application phase.

What this means for you

For CTOs, infrastructure architects, and SMEs evaluating the practical impact of CADA on their infrastructure strategies, the role of grid operators signals a significant shift in due diligence and site selection.

1. Site Selection Must Include Grid Dialogue Early You can no longer treat grid capacity as a secondary check after securing land. Because TSOs and DSOs are involved in the designation of acceleration zones (Article 10(4)), you should engage with local grid operators early in your site selection process. Understanding whether a potential site is within a designated or proposed acceleration zone will determine how your energy needs are reflected in the operator's network development plan. If a site is not in a zone, the mandatory anticipatory planning may not apply.

2. Leverage Anticipatory Investment If you are planning a data centre in an acceleration zone, your projected energy load will legally require TSOs/DSOs to consider it in their network development plans (Article 10(2)(b)). This provides a stronger basis for negotiating connection timelines. You can reference the Member State's obligation to ensure grid operators account for your zone's energy analysis, potentially accelerating the upgrade of local infrastructure. This shifts the burden of proof regarding grid readiness from the developer to the system operator.

3. Monitor Three-Year Review Cycles The energy needs analysis for acceleration zones is reviewed every three years (Article 10(2)(a)). For long-term projects, monitor these reviews. If your project's scale changes, or if new technologies (like on-site storage or clean energy generation, mentioned in Article 10(1)(b)) are integrated, ensure these updates are fed into the Member State's analysis so they flow down to the grid operator's planning. This ensures your project remains aligned with the "anticipatory investments" being made.

4. SMEs and Grid Access While CADA focuses on large-scale strategic projects, the harmonisation of grid planning benefits SMEs by reducing the unpredictability of grid connections. By forcing grid operators to plan for acceleration zones, the proposal aims to reduce the "first-come, first-served" bottlenecks that often disadvantage smaller players. However, SMEs should still verify that local DSOs have the financial and technical capacity to execute the anticipatory investments mandated by the network development plans, as the proposal relies on existing regulatory frameworks for funding.

Common misconceptions

Misconception 1: CADA gives grid operators new powers to refuse connections. CADA as proposed does not grant TSOs or DSOs new discretionary powers to deny connections. Instead, it imposes a planning obligation. Grid operators must plan for the capacity; they do not have the authority to override national designation decisions. Their role is to ensure the grid is technically capable of supporting the designated zones, not to veto the zones themselves.

Misconception 2: Grid operators are responsible for permitting data centres. Grid operators are not part of the permitting process for the data centre building itself. Their role is strictly limited to the electricity infrastructure. Permitting remains the responsibility of national, regional, and local authorities, although Article 10(4) requires coordination between these bodies and grid operators to ensure alignment.

Misconception 3: All data centres benefit from this grid planning mandate. The mandatory integration of energy analyses into network development plans applies specifically to data centres located in designated "acceleration zones" (Article 10(2)(b)). Data centres outside these zones may not benefit from the same level of anticipatory grid planning, as the legal trigger for TSO/DSO action is the existence of a designated acceleration zone.
