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.
