The revision of the European Network Codes Codes Requirements for Generators (RfG) and Demand Connection Code (DCC) is entering a decisive phase as the Commission finally announced the re-start of the legislative process in 2026. The Codes will significantly reshape future grid connection requirements for a broad range of technologies. While the first edition of the Codes as of 2016 focused on generation and general load types, the current revision will extend the regulatory scope to a much wider set of grid-connected resources. In particular, updated requirements are emerging for power generating facilities, energy storage systems, electromobility, power-to-gas facilities, and heat pumps. This reflects the ongoing transformation of the European power system toward a more decentralized, converter-based, and sector-coupled system landscape.

This contribution provides a concise update on the current status of the revision of the European Network Codes and highlights the most relevant developments across these technology groups. It discusses the expected evolution of requirements with regard to system support, controllability, interoperability, and conformity assessment, with a particular focus on the practical implications for connected equipment and grid integration processes.The paper assumes that the European Commission will launch a formal consultation process during the summer and that possible amendments to the 2023 draft versions of the Network Codes will become publicly visible by late summer. Against this background, the contribution analyzes the expected regulatory trajectory and discusses the implications of potential changes in the stipulated requirements.

Beyond a purely regulatory perspective on technical requirements, the contribution will also adress the requirements on conformity assessment as laid out in the extended Codes. A critical evaluation will be provided in the light of stakeholders' requirement on respective compliance schemes.

By summarizing the latest developments in a compact and application-oriented way, the presentation offers guidance for manufacturers, grid operators, planners, certification bodies, and policymakers preparing for the next generation of European connection requirements. The contribution aims to support an early understanding of the regulatory direction and its practical relevance for the secure, interoperable, and efficient integration of emerging grid-connected technologies.
