Data centre energy performance reporting
On 1 July 2025, the Act on the Disclosure of Information on the Energy Performance of Data Centres entered into effect. Here you will find information about what the Act entails.
The Act (2025:570) requires owners or operators of data centres with an installed IT power demand of at least 500 kW to publish annual information on the energy performance of their data centre by reporting data to an EU-wide database.
The obligation to notify and report does not apply to data centres that, under the Protective Security Act (2018:585), are used for security‑sensitive activities, defence purposes or civil contingency purposes, or where services are provided exclusively for such activities.

Purpose of the Act
The purpose of the Act is to promote energy efficiency and the use of renewable energy, as well as to reduce the environmental impact of data centres. Reporting to the EU database will form the basis for establishing a common Union‑wide system for assessing the sustainability of data centres within the EU.
Key Dates
- By 27 April 2026: Notification to the Swedish Energy Agency must be submitted. After notification, you will need to apply for access rights to the EU database in order to report.
- By 15 May 2026: Reporting in the EU database must be completed. The data must cover the full year 2025.
Reporting Now Open
Reporting for the year 2025 is now open in the EU database.
Notification and Registration – Step by Step

Companies that have previously notified the Swedish Energy Agency and reported do not need to submit a new notification. The company retains its reference number from the previous reporting year.
Information on Reporting
On the Commission’s website, you log in to report. The site also contains information needed for reporting: Energy performance of data centres (energy.ec.europa.eu)
Data to Be Reported
Delegated Regulation 2024/1364 specifies which data must be reported. The requirements are set out in Annexes I and II of the Regulation and include, for example, information on the data centre’s energy use, water use, waste heat, and whether the data centre contributes to grid services.
Questions and Answers
On the Commission website you will find answers to common questions about reporting on the energy performance of data centres.
