The energy transition is reshaping Europe’s electricity landscape. As we move toward a more decentralised, digital, and decarbonised electricity system, data interoperability becomes a cornerstone for the efficiency of the system. Data sharing among all relevant actors is the basis for an efficient future electricity system characterised by a wider variety of energy, providers, and users than the former system. As a result, significant efforts have been undertaken at the EU level with the support of ENTSO-E and DSO Entity to ensure transparent and seamless access to final customers’ data, in a manner that the data is easy to understand and use, provided that customers have given the required permission.
Consumers are front and centre in the efforts to digitalise the electricity system with the objective of developing innovative data-driven services to save energy (and money), address high prices, and increase energy sovereignty. For example, interoperability is key for small consumers to participate in demand response through a transparent and unified interoperability framework.
We are pleased to welcome you to this website, which serves as a central point of access to information on electricity data interoperability across Europe. Here, you will find key resources, overviews of national implementations and updates developed in line with the EU legislation.
The aim is to promote transparency, support implementation efforts, and contribute to a more interoperable and efficient electricity system for all actors involved.
Implementing Acts on Data Interoperability
To facilitate the full interoperability of energy services, Article 24 (2) of Directive (EU) 2019/944 empowers the European Commission to adopt, by means of implementing acts, interoperability requirements and non-discriminatory and transparent procedures for accessing to data on metering and consumption data, customer switching, demand response and other services.
Repository of National Practices
The repository of national practices mandated under Commission Implementing Regulation (EU) 2023/1162 of 6 June 2023, is designed to collect the reports of national practices provided by the Member States to the European Commission regarding the implementation of the reference model set out in the Implementing Acts on Data Interoperability.
Interoperability Models
To ensure interoperability, the JWG also maps the reference models included in the European Commission’s Implementing Acts against European standard models such as the HEMRM or CIM.
Reference models for interoperability
To promote interoperability, reference models have been set up to define common rules and procedures at the EU level for the business, function and information layers. The business layer specifies the business objectives and roles for certain services and processes; the function layer provides use cases; and the information layer defines data model and information models.
A reference model is composed of
A role model with a set of roles and responsibilities and their interactions
An information model that contains information objects and their attributes
A process model (or use cases) detailing the procedural steps
Joint Working Group (JWG) on Data Interoperability
The JWG on Data Interoperability is a cooperation between ENTSO-E and DSO Entity established in June 2023 to perform the tasks foreseen in Articles 11, 12 and 13 of Commission Implementing Regulations (EU) 2023/1162 of 6 June 2023.
ENTSO-E
ENTSO-E, the European Network of Transmission System Operators for Electricity, is the association for the cooperation of the European transmission system operators (TSOs). The 40 member TSOs representing 36 countries are responsible for the secure and coordinated operation of Europe’s electricity system, the largest interconnected electrical grid in the world. In addition to its core, historical role in technical cooperation, ENTSO-E is also the common voice of TSOs.
EU DSO Entity
Established in June 2021 by the Clean Energy Package (CEP), DSO Entity is the legally mandated association for the European Distribution Operators (DSOs). It provides expertise for energy distribution to final customers: homes, industries, and other end-users. DSOs are the backbone of the energy transition that integrate up to 70% of renewable energy sources and enable consumers to participate in an increasingly decentralised energy system.
