Network Code Requirements for Generators (RfG)

The Network Code describes the grid connection requirements for generators at all voltage levels. It focuses on the cross-border electricity trade. The regulations include, for example, capabilities for frequency stabilization, provision of reactive power to the point of black start capacity of large installations.

Backing the creation process

VDE|FNN has closely followed the Network Codes "Requirements for Generators" and submitted proposals for improvement regularly.

  • Classification in performance categories: Voltage-depending power classification in accordance with national regulations must be observed. 
  • The existing national classification by voltage levels is referred to both in the existing connection conditions and also in guidelines and eligibility conditions. 
  • Definition of clear areas of responsibility (e.g. provisions relating to the access of the TSO to NO in active power control)

Definitions need to be harmonized and explicitly demarcated:

  • e.g. power generating facility / power generating module / power park module 
  • Requirements in Germany refer to the grid connection point
