Swedish Energy Agency Sustainability Data centre energy performance reporting

Data centre energy performance reporting

On 1 July 2025, the law on the disclosure of information about data centres' energy performance came into effect. Below you can find information about what the law entails.

The Swedish law (2025:570) requires owners or operators of data centres with an installed IT power demand of at least 500 kW to annually disclose information about the energy performance of the data centre by reporting data to a common EU database.

Act 2025:570 on the Disclosure of Information on Data Centres' Energy Performance (in Swedish, riksdagen.se)

The reporting obligation does not apply to data centres used for security-sensitive operations, defence, or emergency preparedness purposes under the Security Protection Act (2018:585), or where services are provided exclusively for such purposes.

Report by 15 May  2026

Reporting must be completed by 15 May  2026, and the data should cover the full year of 2025. The Swedish Energy Agency is the national coordinator and provides Swedish data centres access to the EU database. To report, companies must first notify the Swedish Energy Agency and then register in the EU database.

Notification and registration in the EU database

Notify the Swedish Energy Agency

Registrate your company by emailing the company name and company email address to infodep@energimyndigheten.se. The email address can be created specifically for reporting, for example, EEDreporting@company.com or another relevant functional mailbox.

The Swedish Energy Agency will register the company name and email address in the EU database. Note that submissions to the agency become public records, so only send the company name and email address.

Create an EU Login account

To access the database, you need to create an EU Login account via the EU Login website: EU Login (ecas.ec.europa.eu)

Use the same company email address as you submitted to the Swedish Energy Agency for this login.

Apply for reporting access in the EU database

Once your company has been  confirmed, you can apply for access as a reporting entity representative.  Log in with the company email via the EU Database Policy Reporting Platform (ecas.ec.europa.eu)

A form will appear. Make the following selections:

  • Account type: Reporting entity representative
  • Justification: Data Centre Operator
  • Country: Sweden
  • Represented reporting entity: Select your company from the list.

Once access is approved and verified, the company can begin reporting.

Reporting to the EU database

Companies must report directly to the EU database via Policy Reporting Platform (ecas.ec.europa.eu).

The European Commission’s website provides compiled information about the reporting: Energy Efficiency Directive (energy.ec.europa.eu)

Data to be reported

Delegated Regulation 2024/1364 specifies the data to be reported. The requirements are described in Annexes I and II of the regulation and include information about energy use, water use, waste heat, and whether the data centre contributes to grid functions.

How Is the reported data handled?

Data submitted to the EU database and accessible to the Swedish Energy Agency is protected under confidentiality provisions in Chapter 15, Sections 1–1b of the Swedish Public Access to Information and Secrecy Act (2009:400).

+
−

How is the data made public?

Reported data will be available to the public in aggregated form at both member state and EU levels, according to Annex IV of Delegated regulation 2024/1364 (eur.lex.europa.eu)

Purpose of the law

The purpose of the law is to promote energy efficiency and the use of renewable energy, and to reduce the environmental impact of data centres. The reporting to the EU database will form the basis for a common EU system for assessing the sustainability of data centres.

Articles in the Energy Efficiency Directive (EED) related to data centres

On 10 October  2023, the revised EU Energy Efficiency Directive 2023/179 came into force. Below are the articles in the directive that affect data centres.

Article 12 – data centres

According to Article 12, member states must ensure that owners or operators of data centres with an installed IT power demand of at least 500 kW make information about energy performance publicly available. In Sweden, this is done by reporting to the EU database.

+
−

Article 12.4 – EU Code of Conduct for Energy Efficiency

Article 12.4 encourages member states to promote best practices according to the latest version of the EU Code of Conduct for Energy Efficiency in data centres for facilities with an installed IT power demand of at least 1 MW.

The EU Code of Conduct is available here: The Joint Research Centre: EU Science Hub (joint-researrch-centre.ec.europa.eu)

Proposed amendment to the law (2013:268) on certain cost-benefit analyses

According to Article 26.6 of the revised directive, member states must ensure that data centres with a total energy supply level above 1 MW use waste heat or other recovery applications, unless it can be shown that it is not technically or economically feasible.

The legislative proposal is under consultation until 4 November 2025.
