Regulations for grid connection of new facilities

Generation facilities

Requirements for grid connection under Requirements for Generators (RFG)

Translations will be added when these are complete. In the meantime, you are welcome to read the requirements in Danish here.

The RfG requirements apply to all new generation facilities >0.8 kW. They also apply when significant changes are made to category C and D facilities.
Facilities connected in the distribution grid are also subject to the requirements in the grid enterprises' technical conditions. Find these here on the website of Green Power Denmark, the Danish professional body representing Danish energy companies (Danish only).

HVDC

The connection of high-voltage direct current facilities is subject to Commission Regulation (EU) 2016/1447 of 26 August 2016 establishing a network code on requirements for grid connection of high voltage direct current systems and direct current-connected power park modules.

Self-assessment

Under the three EU regulations

  • RfG (Requirements for Generators) - Article 41
  • DCC (Demand Connection Code - Article 35
  • HVDC (High Voltage Direct Current) - Article 70

Energinet must assess whether any facility connected to the transmission system under one of the three regulations complies with the applicable requirements throughout its service life.
 
Energinet uses two procedures to make this assessment:

  • a self-assessment procedure, and
  • a procedure for follow-up on unintended false tripping in the transmission system.
    The three templates below for demand facilities, generation facilities and distribution systems, respectively, are used for the self-assessment procedure.
Title
Template DSO - Self-assessment - start-up of review of requirement compliance 
Template demand facilities - Self-assessment - start-up of review of requirement compliance 
Template generation facilities -Self-assessment - start-up of review of requirement compliance 

As for the procedure for follow-up on unintended false tripping in the transmission system, Energinet makes an individual assessment in cooperation with the facility owner in each specific case.

Time intervals and contact

Distribution systems: Every 5 years

Demand facilities: Every 3 years

Generation facilities: Every 3 years
