Rules, conditions, and methods

RfG:

Commission Regulation (EU) 2016/631 of 14 April 2016 establishing a network code on requirements for grid connection of generators

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).

Moreover, a grid connection process walk-through is available.

NC DC:

Commission Regulation (EU) 2016/1388 of 17 August 2016 establishing a Network Code on Demand Connection

Demand facilities and distribution systems connected above 100 kV as of 18 August 2019 are subject to the requirements in the Network Code on Demand Connection (NC DC).

Updated requirements available: https://energinet.dk/regler/el/nettilslutning/

Moreover, a grid connection process outline is available.

Moreover, a grid connection process outline is available.

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.

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
