The European network codes are network requirements for a cross-border electricity exchange harmonized on a Europe-wide basis. The goals are to improve the internal market for electricity and establish a functional and transparent wholesale market.

There are requirements on structuring conditions under national law apart from the concrete guidelines that are legally binding in every Member State. VDE FNN takes over this task for Germany on behalf of the Federal Ministry for Economic Affairs and Energy (BMWi). VDE FNN describes in the VDE-Applications Rules both the concrete EU specifications and the specifics for the German electric power system. The German rules are distinguished by voltage levels since the requirements for grid connection depend on them. A transfer to VDE-Application Rules creates user-friendly and consistent rules and standards. Users that comply with the Application Rules will also adhere to the European Network Codes.

ACER submits the Network Code on cybersecurity to the European Commission

ACER has submitted a revised Network Code after the preparation of the Network Code by ENTSO-E and the DSO Entity in January 2022, based on the Framework Guidelines established by ACER. This revision was submitted to the European Commission within the allowed limit of six months (EU 2019/943; Article 59, 11). The Commission should now review the Network Code and initiate its adoption as a delegated act. More information on the revised parts of the Network Code can be found here.

DSO-TSO Roadmap on the Evolution of the Regulatory Framework for Distributed Flexibility

The recommendations of the report are the outcome of 5 months of analysis and discussion between TSO and DSO experts involved in a Joint Task Force on Distributed Flexibility, which was set up in the framework of the Distribution & Transmission Cooperation Platform. Two diverging perspectives appeared regarding the necessary evolution of the regulatory framework, whereby TSOs advocated for amendments to existing NCs and guidelines (GLs) and DSOs favoured the development of a new NC. The proposed roadmap lays out the necessary changes in regulation but the implementation as a separate NC is still not decided.

ACER publishes its Framework Guideline to establish a Network Code on Cybersecurity

The next step towards the development of a Network Code is the publication of a Framework Guideline which provides hihg-level principles for the development of the NC on Cybersecurity. The document was consulted with stakeholders in April 2021 and updated according to the comments received. FNN Experts from the Expert Network on EU NC submitted their opinions putting emphasis on the importance of standardization as the basis for the NC. The Framework Guideline was then submitted to the EU COM, who will request ENTSO-E a drafting of the NC within 12 months. This will be done together with the DSO-Entity, particularly through ist Expert Group dedicated to the NC on Cybersecurity.

The DSO Entity celebrated its first General Assembly with all DSO members and the elected Board from April this year. Johan Mörnstam (E.ON Group) was elected one of the Vice President for the category representing the DSOs over 1 million connected customers of the EU DSO Entity. According to Eurelectric "The activities of the body have since officially started, centered around three expert groups on cybersecurity, data access and interoperability, and distributed flexibility. This work will enable the Entity to set up a constructive collaboration with, among others, the European Commission, ACER and ENTSO-E."

Energy Transition and European Single Market Challenge

EU regulations and overall guidelines specify close intervals to prepare European Network Codes and require strong commitment and fast positioning from all stakeholders involved. VDE FNN as the national standardization body works towards ensuring that the European requirements harmonize well with the German regulations and will support further integration of renewable energy.

VDE FNN accompanies the European activities and implements the European regulations in Germany. The challenge is to specify the goals of the energy transition and of cross-border electricity trade as rules involving all expert groups. The rules need to pass through a notification procedure at the EU commission upon completion by VDE FNN.

The European Network Codes must be implemented nationally within three years of publication.

FNN principles governing implementation

  • We announce the creation of Application Rules and make the procedure transparent.
  • We publish drafts, discuss the incoming proposed modifications and inform the objectors about the result.
  • We make controversial topics (hotspots) and overarching specifications transparent in good time.
  • We involve interest groups to reflect and involve a wide range of opinions
  • Our procedure is proven, tested and transparent. It follows the principles of developing VDE-Application Rules in the FNN (VDE-AR-N 100).

Overarching themes

The challenges of expanding renewable energies, particularly in the underlying grids, need to be tackled jointly by all stakeholders of all network levels. For this reason, some topics will need to be addressed and regulated across voltage levels, for example:

  • Classification in performance categories
  • Notification of the VDE code of practice through the EU Commission
  • Static voltage stability
  • Dynamic network support
  • Black start capacity
  • Active power supply for over or under frequency
  • Balancing energy
  • Verification procedures

The rules need to pass through a notification procedure at the EU commission upon completion by VDE|FNN.
