Network Code on Demand Connection (DCC)

The European Network Code on Demand Connection includes harmonized regulations for grid connection of consumption and distribution systems. It focuses on the cross-border electricity trade. Load management, load-side matchings and demand side response are being addressed by the code as well as new rules for the cooperation of system and network operators.

  • Publication in EU Official Journal: August 17, 2016
  • In force: September 7, 2016
  • Implementation in national rules through VDE|FNN not later than September 7, 2018
  • Implementation by grid operators and manufacturers no later than August 17, 2019

Backing the creation process

VDE|FNN has closely followed the Network Codes creation process and regularly submitted proposals for improvement.

  • Requirements do not refer to the grid connection point 
  • Interfaces between transmission system and distribution system operators
  • Frequency-stabilizing measures by the transmission system operator should be carried out in coordination with the distribution system operator
  • Definitions must be harmonized and clearly defined (e.g. significant load)
  • Demand side response requirements should be reduced to technical requirements
