A new deal for energy consumers: consumer data management

A new deal for energy consumers

From the Clean Energy Package to the future of Electricity Network Codes

FSR Topic of the Month by Athir NouicerValerie ReifTim Schittekatte 

In this Topic of the Month, we look at new developments in the area of electricity network codes and guidelines that were triggered by the recent adoption of the Clean Energy Package (CEP). The recast of the electricity Regulation (Regulation (EU) 2019/943) explicitly lists several areas for new network codes and guidelines. In many other areas, the electricity Directive (Directive (EU) 2019/944) allows Member States to first experiment with innovative regulation. Best practices may later inspire the development of new European principles or rules or point out necessary amendments to network codes and guidelines.

The research FSR Energy conducts on these areas is done in the context of the European H2020 project INTERRFACE (“TSO-DSO-Consumer INTERFACE aRchitecture to provide innovative grid services for an efficient power system”). INTERRFACE brings together more than 40 partners from all across the electricity sector. Besides thinking about future regulation, several pilots are also being set up as a part of the project.

Week 2. Consumer data management

by Valerie Reif

What is it about?

Consumers have been given the right to access and share their own energy data by recent EU legislation from the Third Energy Package and the General Data Protection Regulation (GDPR) to the Clean Energy Package (CEP). As part of the CEP, the recast of the e-Directive (Directive (EU) 2019/944) lays down general principles for how Member States should deal with consumer data. Among others, they require Member States to create an adequate regulatory framework to organise the management of consumer data.

Existing Data Management Models (DMMs) vary a great deal across Member States [1]. They typically consist of a set of different roles, responsibilities, legal frameworks, technical standards as well as informal rules. DMMs can be categorised according to numerous different dimensions, yet a fundamental distinction can be made between centralised and decentralised models, as shown in Figure 1 and described below according to a report by CEER. The centralised models are structured as Data Exchange Platforms (DEPs), which can either be a fully centralised model (data hub) or a partially centralised model (communication hub).

Figure 1: Overview of types of data management models

  • In a decentralised model, the key aspects of data management are decentralised and within the DSO’s responsibility. The means of exchanging data among market parties and the DSO is often a rather simple format, sometimes standardised yet often non-standardised. Customers have to specifically contact the DSO for access to data.
  • In a partially centralised model one or few key aspects of data management are centralised, typically distribution and access to data. This model thus enables centralised access (via the communication hub) to data stored in several decentralised databases (at DSOs or at metering points).
  • A fully centralised model comprises the centralisation of all key aspects related to data exchange. It typically represents a one-stop shop for data, where DSOs, market actors and all consumers have only one actor, the data hub, which they relate to.

In many Member States, the choice between centralised and decentralised models can be assumed to be a mere result of the existing legacy systems. While traditionally, consumer data was exchanged bilaterally, now more and more MS are transitioning from a decentralised to a more centralised approach. However, large disparities remain across Member States. When assessing these large disparities in DMMs across Member States in its Impact Assessment for the Market Design Initiative in 2016, the European Commission identified three options for future DMMs: (i) sole responsibility by the Member State, (ii) common criteria and principles and (iii) a common EU model. Both the European Commission and network companies (both TSOs and DSOs) share the view that option number two, common criteria and principles, is the most suitable way forward.

What does the Clean Energy Package say?

Despite the widespread agreement that the best solution for managing consumer data must be assessed for each national context, it is acknowledged that a lack of standardisation and interoperability can pose barriers to retail competition [2]. More precisely, it can create entry barriers to mainly national retail markets for established suppliers who want to expand their business to other Member States [3]. The need for interoperable solutions is also reflected in the provisions of the Clean Energy Package.

Article 23 of the e-Directive states that Member States shall organise the management of data to ensure efficient and secure data access and exchange, as well as data protection and data security. It is important to note that the Clean Energy Package expresses no preference of one DMM over the other. Instead, the principles laid down apply independently of the DMM. To ensure compliance with the requirements of the e-Directive, the Member State or a designated competent authority shall authorise and certify, or where applicable, supervise, the parties responsible for the data management.

Further, Article 24 of the e-Directive addresses the need for Member States to facilitate the full interoperability of energy services within the Union to promote competition in the retail market and to avoid excessive administrative costs.

Which Network Code and Guideline Areas are relevant?

In the domain of consumer data management, none of the designated areas for new network codes listed in Article 59 of the e-Regulation can be directly applied.

However, regarding interoperability, Article 24 of the e-Directive also states that the Commission shall adopt, by means of implementing acts, interoperability requirements as well as non-discriminatory and transparent procedures for access to data. According to the CEP, network codes can henceforth be adopted either as delegated or implementing acts. This may thus open up the possibility for interoperability requirements and procedures for data across all Member States to be defined by means of a new network code. The European Commission currently considers such an implementing act among the three most important acts to be addressed based on the provisions in the Clean Energy Package, as expressed in the context of the Florence Forum 2019.



[1] As explained in the report on TSO-DSO Data Management by ENTSO-E, Eurelectric, EDSO, GEODE and CEDEC, a data management model refers to ‘the framework of roles and responsibilities assigned to any party within the electricity system and market and the subsequent duties related to data collection, processing, delivery, exchanges, publishing and access.’

[2] The e-Directive defines interoperability, in the context of smart metering, as ‘the ability of two or more energy or communication networks, systems, devices, applications or components to interwork to exchange and use information in order to perform required functions.’

[3] One example in this context are the Nordic countries that have been working towards harmonising their electricity retail markets since 2005. NordREG states that the aim is not to implement one single retail market, but among others to reduce market entry barriers for retailers who want to extend their business to other Nordic countries. To facilitate harmonisation, all Nordic countries are moving towards the implementation of data hubs for metering data and market processes. The harmonisation of business processes is largely completed. However, on the more technical level a supplier currently needs to comply with one interface for each hub, which constitutes a market barrier due to the need and costs to operate four IT subsystems in parallel.
