Summary As proposed, the Cloud and AI Development Act (CADA) does not impose a blanket rule that every data centre must reuse its waste heat. Instead, it embeds waste-heat reuse into the planning and permitting framework for "data centre acceleration zones." Member States must consider the available and future facilities that can reuse data centre waste heat when designating zones (Article 10(1)(e)), and single information points must help operators with authorisations for "heat utilisation and recovery" (Article 12(2)(c)). Waste-heat reuse also appears as a progress-monitoring indicator and as a Title II innovation focus — so it is strongly facilitated, not universally mandated.

Detail

CADA aims to accelerate data centre deployment across the EU while supporting sustainability, principally through "data centre acceleration zones." Within that framework, waste-heat reuse is treated as a factor in site selection and administrative support rather than a standalone operational requirement for every facility.

Planning for waste-heat reuse in acceleration zones

The primary hook is Article 10, on the designation of acceleration zones. Article 10(1) lists aspects Member States "shall consider when designating acceleration zones." Point (e) requires consideration of "the available and future facilities that can reuse data centre waste heat."

This shifts heat integration into the planning phase. Rather than leaving an operator to find a heat sink after construction, the proposal encourages siting zones where suitable infrastructure — district heating networks, greenhouses, industrial processes — exists or is planned, so new data centres can put their thermal output to use.

Administrative support for heat recovery

Once a zone is designated, Article 12 supports implementation through "single information points." Article 12(2) provides that the role of a single information point may include coordinating, facilitating, monitoring and sharing information on procedures relating to, among other things, "(c) authorisations regarding water abstraction, wastewater discharge, and heat utilisation and recovery." By covering heat utilisation and recovery, CADA recognises that permits for connecting to heat networks or installing recovery systems can be complex, and tasks the single information point with streamlining them.

Sustainability requirements and indicators

CADA links deployment in acceleration zones to sustainability requirements. Article 11(1) provides that, when setting those requirements, Member States shall use the key performance indicators specified in Delegated Regulation (EU) 2024/1364, pursuant to Directive (EU) 2023/1791 (the Energy Efficiency Directive), under Annex II, points (a) to (n). These cover metrics such as Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE).

Beyond the zone-level KPIs, the proposal's own monitoring framework lists "Share of clean energy in data centres and waste-heat reuse" as an indicator of progress — so reuse is explicitly tracked at EU level, even though it is not the subject of a stand-alone operator obligation.

Strategic projects and innovation

For data centres designated as "strategic projects" under Article 14, sustainability weighs heavily. The Commission may designate projects (selected through open calls for expressions of interest) that meet at least two of the listed criteria, one of which is including "highly sustainable or innovative features, including technologies and solutions developed under Title II" (Article 14(1)(b)). Title II leadership initiatives expressly back "waste heat utilisation solutions," so a project with advanced heat recovery would be well placed against that criterion.

What this means for you

For CTOs, architects and SMEs assessing CADA's practical impact:

Site selection and planning. Prioritise acceleration zones, and assess existing and planned waste-heat-reuse infrastructure for each candidate site. Because Article 10(1)(e) requires Member States to consider such facilities when designating zones, zones are likely to be located near heat consumers — reducing the risk of having no viable heat sink after construction.

Regulatory compliance and permitting. Engage early with the single information point in your target Member State. Under Article 12(2)(c) it is meant to assist with authorisations for heat utilisation and recovery, which can shorten timelines for connecting to heat networks or installing recovery systems.

Strategic-project applications. If your project incorporates innovative waste-heat-reuse technology, highlight it when seeking strategic-project designation under Article 14(1)(b); it can help satisfy the "highly sustainable or innovative features" criterion.

Existing operators. CADA primarily targets new deployments in acceleration zones, but its emphasis on reuse and its monitoring indicator signal the direction of EU expectations. Reviewing heat-management strategies now is prudent.

Common misconceptions

Misconception 1: CADA mandates 100% waste-heat reuse for all data centres. Incorrect. CADA does not impose a universal reuse requirement. It focuses on planning and facilitation: Member States must consider reuse facilities when designating zones (Article 10(1)(e)) and single information points must assist with related authorisations (Article 12(2)(c)). Actual reuse depends on national requirements and project feasibility.

Misconception 2: Waste-heat reuse is only a suggestion with no regulatory weight. It is a designation factor for zones, a facilitation duty for single information points, an EU-level monitoring indicator, and a feature that can support strategic-project designation. Ignoring it could limit access to accelerated pathways and their benefits.

Misconception 3: The single information point handles the technical side of heat recovery. The single information point (Article 12) is an administrative facilitator. It coordinates and shares information on authorisations; it does not design recovery systems or guarantee a heat sink. Technical design and commercial agreements remain the operator's responsibility.
