Electricity metering and consumption data interoperability : guidance for the reporting of national practices in accordance with Commission Implementing Regulation (EU) 2023/1162

This document has been developed to assist Member States in fulfilling their reporting obligations under Commission Implementing Regulation (EU) 2023/1162 which addresses interoperability requirements and establishes non-discriminatory and transparent procedures for accessing electricity metering and consumption data. This Implementing Regulation was adopted in June 2023 as the first in a series of implementing acts under the Electricity Directive and marks a significant milestone in the Digitalisation of Energy Action Plan. These new technical rules aim to lower barriers for new market entrants, optimise operations for retailers and system operators, and foster innovation in energy services, notably in energy efficiency and renewable energy. The new rules set out in Commission Implementing Regulation (EU) 2023/1162 will apply from 5 January 2025, and Member States must then report, by 5 July 2025, their respective national practices to the Commission for inclusion in an EU wide repository. This repository will be a key tool in allowing market players from across the EU to develop products and services more easily and quickly for different parts of the internal market. This will enhance transparency, trust, efficiency, and predictability in data exchanges while supporting a wider choice and opportunities for consumers. This Guidance is a result of extensive collaboration and consultation with the Joint Working Group (JWG) of European network operators ENTSO for Electricity (ENTSO-E) and the EU DSO entity. It facilitates the accurate implementation and reporting of national practices in line with these new technical rules. In doing so, this Guidance, and as part of the underlying legislation, contributes to advancing the objectives of the European Green Deal and REPowerEU. This Guidance also underscores our commitment to providing clear, practical, and impactful support to Member States as we jointly navigate the transformative path toward a more consumer-centric, decarbonised, decentralised and digitalised energy landscape.
