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; subsequently European notification
Inclusion in VDE body of technical standardization on October 19th, 2018.

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
