Rules, conditions, and methods
Find translated rules, conditions, and methods for grid connection and system operation.
Please note that translations are not available for all rules, conditions, and methods, meaning that many texts are only available in Danish. To get a full picture of the requirements, you must therefore consult our Danish list of requirements on our Danish site.
Translations of the original Danish texts are for informational purposes only and not substitutes for the official Danish texts. The English texts are not legally binding and offer no interpretation on the Danish texts. In case of inconsistency, the Danish versions apply.

Generation facilities (Requirements for Generators (RFG))
RfG:
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).

Self-assesment
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

As of 1 January 2023, Technical regulation 3.3.1 Electrical energy storage facilities, revision 3, which is available in Danish only, replaced revision 2. Revision 3 contains primarily editorial corrections as well as changes made at the request of the Danish Utility Regulator.
System operation
Please visit our Danish site for the full list of requirements. More documents will be added as these are translated.
System operation concerns the regulation of system operation and responsibilities related to system operation and also operational reserves, operational procedures, operational planning, staff training and emergency preparedness, requirements for control equipment in control centres, and requirements for exchange of operational measurements (including real-time measurements and operational status). Furthermore, the regulations for system operation set the requirements for handling emergency preparedness situations and system disturbances, e.g. frequency load shedding and disconnection of electricity generation.
