Summary As proposed, the Cloud and AI Development Act (CADA) does not mandate that data centres run exclusively on clean energy. Instead, Article 10(1)(b) requires Member States to consider "the possibility and conditions for on-site storage and clean energy generation" when designating data centre acceleration zones. CADA tracks the share of clean energy as a monitoring indicator and encourages Power Purchase Agreements (PPAs), but its binding obligations centre on energy efficiency, grid integration and preventing speculative reservation of resources — not a strict 100% renewable rule for operators.
Detail
CADA aims to triple EU computing capacity in the next five-to-seven years and reach the needed capacity by 2035, while supporting sustainability. Its approach to clean energy is to incentivise and facilitate the transition rather than to impose a direct obligation on every operator to source 100% renewable electricity.
Acceleration zones and clean-energy criteria
The main lever is the designation of data centre acceleration zones. Under Article 10(1), where data centre capacity is being deployed, a Member State must designate at least one acceleration zone (within six months of entry into force) and must consider a list of aspects when doing so.
Among them, Article 10(1)(b) requires Member States to consider:
"the available and future power grid capacity and the possibility and conditions for on-site storage and clean energy generation;"
So when a Member State selects a zone location, it must evaluate local clean-energy potential. This encourages siting data centres where renewable infrastructure is strong or on-site generation is feasible. It does not force an operator to build on-site generation; it requires the Member State to factor the potential into strategic planning of the zone.
Encouragement of Power Purchase Agreements (PPAs)
CADA does not prescribe contractual instruments, but it supports market mechanisms for clean-energy access. Recital 38 highlights PPAs, stating, as proposed:
"Power purchasing agreements ('PPAs') are important instruments for data centres as they provide long-term price stability, while enabling data centre operators to procure clean electricity at scale, thereby supporting reliable operations and the transition to a clean energy system. Member States should therefore promote the uptake of PPAs, also in acceleration zones, by removing unjustified barriers and disproportionate or discriminatory procedures or charges, with a view to providing price predictability."
The policy intent is to reduce regulatory friction for PPAs. For CTOs and architects, this suggests national implementation may bring clearer or streamlined conditions for large-scale corporate PPAs.
Monitoring and indicators
CADA establishes monitoring of the cloud ecosystem. There is no direct penalty for using fossil fuels, but the proposal's accompanying monitoring indicators include "Share of clean energy in data centres and waste-heat reuse" as a measure of progress toward increasing sustainable computing capacity. This is a monitoring tool rather than a per-operator compliance threshold, but it makes the clean-energy share a visible, reported metric for the sector.
Sustainability requirements in acceleration zones
For data centres in acceleration zones, Member States must set sustainability requirements. Article 11(1) requires those requirements to use the KPIs specified in Delegated Regulation (EU) 2024/1364 (under Directive (EU) 2023/1791), Annex II, points (a) to (n). These focus on efficiency metrics such as Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE); by mandating high efficiency, CADA indirectly reduces total energy demand, making a shift to clean sources more feasible.
Article 11(2) further requires that allocation and use of resources within acceleration zones take place on "fair, reasonable and non-discriminatory terms" and not give rise to speculative reservation or foreclosure — reinforced by Recital 39. This helps ensure that operators genuinely intending to build sustainable data centres can access the necessary resources, rather than having them locked up speculatively.
What this means for you
For CTOs, architects and SMEs, the absence of a hard "100% clean energy" mandate offers flexibility but rewards planning.
- Site selection is critical. Prioritise acceleration zones with strong clean-energy potential. Under Article 10(1)(b), zones are selected partly on the feasibility of on-site clean generation and storage; a zone with poor renewable infrastructure may limit sustainability credentials and access to support.
- Leverage PPAs. With Recital 38 encouraging PPAs and Member States expected to remove barriers, securing long-term renewable contracts can provide price stability and strengthen your position where "Union added value" criteria apply in public procurement (Article 32).
- Track the clean-energy share. Be ready to report on the clean-energy (and waste-heat-reuse) metric used in CADA's monitoring. Though not yet a per-operator compliance threshold, it will shape industry benchmarks and perception.
- Efficiency first. Focus on efficiency technologies (cooling, server utilisation) measured by the Article 11 KPIs. Lower total demand makes sourcing the remainder from clean energy easier and cheaper.
Common misconceptions
-
"CADA mandates 100% renewable energy for all data centres." Incorrect. CADA imposes no blanket 100% clean-energy obligation. It requires Member States to consider clean-energy potential when designating zones and encourages PPAs; the binding obligations concern efficiency, grid connection and permitting.
-
"On-site clean energy generation is mandatory." No. Article 10(1)(b) requires Member States to consider the possibility and conditions for on-site generation when designating zones; it does not require every operator to build on-site renewables, though sites with such potential may be favoured.
-
"PPAs are legally required." No. Recital 38 says Member States should promote PPA uptake by removing barriers. This is policy encouragement for regulators, not an obligation on operators to sign PPAs.
-
"CADA replaces national energy laws." No. CADA complements existing EU energy legislation, such as the Renewable Energy Directive and the Energy Efficiency Directive, rather than replacing national rules on energy sourcing.
