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.

  • Publication in EU Official Journal: April 28, 2016
  • In force: May 17, 2016
  • Implementation in national rules through VDE|FNN not later than May 17, 2018
  • Implementation by grid operators and manufacturers not later than April 28, 2019

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
