Regulations for grid connection

Regulations governing the connection of electricity-generating facilities to the public electricity supply grid

Connection of generation and demand facilities as of 27 April 2019

Note that all new connections must meet the requirements in EU regulations RfG (as of 27 April 2019) and NC DC (as of 7 September 2019) for generation and demand facilities, respectively. Translations of the applicable Danish requirements will be published here as they are completed: Regulations for new facilities.

The regulations specify the system properties that facilities must have in order to be connected to the Danish public electricity supply grid as well as the grid impacts facilities must be able to withstand in order to continue to provide stable operation.

As requirements are revised, the replaced revisions will be available below as they still apply to the facilities that were connected when the specific revision was applicable.

Please note that in case of any discrepancies, the Danish version of the technical regulations prevails.

 

Generation facilities, existing and new energy storage facilities (battery facilities) and voltage quality requirements

See below for applicable requirements for generation and demand facilities, existing and new energy storage facilities (battery facilities) and voltage quality requirements for generation facilities connected to the transmission grid. Please visit the Danish grid connection page for requirements for existing demand facilities.
