Spain Accelerates Data Center Regulation and Opens Debate on Energy and Investment

The Government has agreed to urgently process a draft royal decree to establish energy and environmental sustainability, operational resilience, and digital sovereignty requirements for data centers in Spain. This decision begins the proposal’s administrative process, but it does not mean that the regulation has been definitively approved: the text must still undergo public consultation and hearings and complete the relevant procedures.

The initiative comes at a time of growing demand for computing capacity, driven, among other factors, by artificial intelligence and digital services. For the Government, the challenge is to support the sector’s growth with rules on the use of energy and resources, infrastructure security, and information processing.

Renewable energy: the requirement raising the most questions

According to information published about the draft, one of the proposed requirements is that at least 80% of the electricity consumed by data centers come from renewable sources. The proposal adds conditions for hourly matching between consumption and generation and for additionality: the associated renewable energy would have to have been installed to meet demand, with a reference period of 18 months before the facility begins operating.

Available coverage describes these criteria in varying levels of detail. Therefore, their exact wording, how compliance with them is demonstrated, and how they are applied will have to be confirmed in the text that is ultimately processed. In particular, the proposal must not be confused with an obligation already in force.

The sector calls for proportionality and legal certainty

SpainDC expressed concern about some of the approaches communicated during the process and argued that the targets must be achieved through regulation that is proportionate, technically feasible, and aligned with the European framework. The association said that requirements that are difficult to meet could affect the viability of new projects, planned investments, and Spain’s ability to compete for capital with other European markets.

Aelec welcomed the work to establish a framework for organizing the sector, but highlighted the need to reconcile growing electricity demand with decarbonization and the development of the energy system. Ametic, for its part, called for regulatory fragmentation to be avoided and argued that the regulation should provide legal certainty and encourage investment.

There was also criticism from Aragon. The regional Economy Minister, Eva Valle, lamented that the central Government had not contacted the autonomous communities to present the proposal to them, according to published information.

A proposal affecting several areas of business management

The draft combines issues that typically fall to different teams: energy planning, facility design and operation, environmental management, regulatory compliance, and data governance. For companies developing or operating projects, the debate over renewable energy and hourly matching may affect how energy supply is structured; the resilience and digital sovereignty requirements, in turn, relate to service continuity and control of information.

However, while the royal decree remains under consideration, the requirements described cannot be treated as definitive obligations, nor can their final scope be established. Companies with projects in development will need to follow the text’s progress and distinguish between the conditions proposed in the available reports and those that may, where applicable, be included in the approved regulation.

Urgent processing speeds up the administrative process, but does not resolve the balance at the heart of the debate: how to regulate the energy consumption and impacts of strategic infrastructure without introducing requirements that, in the view of business associations, hinder its deployment or reduce Spain’s competitiveness.
