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.

Grid connection new facilities

Generation facilities (Requirements for Generators (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.
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

System operation

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.
