Synergy with European standardization

New regulations, directives, resolutions and standards are continuously being developed at European level; these must be also implemented in Germany at national level.

In a nutshell

  • VDE FNN takes into account existing and, as far as possible, upcoming European regulations and standards when setting rules for Germany
  • VDE-Application Rules specify further European regulations if necessary

European regulation

European Network Codes are of a legal nature and must be incorporated into national policies and in some cases specified. In addition to issue-specific guidelines and regulations, general European directives such as the Internal Electricity Market directive are also considered when drafting Application Rules in VDE FNN.
