Network codes

Network codes are EU regulations for operation, markets and grid connection for the European electricity system. Internationally, network codes are also known as guidelines.

Energinet prepares and participates in the preparation of national, joint European and joint regional requirements, terms, methods and conditions (national implementation measures). These are submitted to and must be approved by the Danish Utility Regulator (Danish text only) before they take effect. We will publish translations here as these are completed. Note 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.


Please note:

Market-related network codes are available on our Danish site.

New grid 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.

Please note the effective dates listed for the respective requirements. Older facilities may be governed by either EU regulation or technical regulations (links available below).

Regulations for older facilities

The regulation of facilities is important in order to ensure the physical operation and system security of interconnected high-voltage grids. The regulations are primarily aimed at grid companies, plant owners and plant operators. International obligations in connection with the physical system operation have typically been implemented in technical regulations.

The regulations specify functional requirements and principles for the entire power system, system properties for grid-connected plants and rules governing how to act to ensure stable, reliable system operation. They also specify the ancillary services which electricity-generating plants must supply to the grid, outline guidelines for the decommissioning of plants, assign responsibility for the provision of measurements for system operation purposes and the preparation of communication procedures - for day-to-day operation as well as alert states.

Market regulations

The rights and obligations of grid companies and commercial participants in the Danish electricity market are regulated by the market regulations.

The market regulations are guidelines that are necessary in order to ensure that the electricity market functions properly and that settlement is performed correctly. The market regulations deal with issues such as terms and conditions for change of supplier, daily handling of notifications, balance settlement and standards governing the transfer of data between players.

The market regulations are primarily aimed at balance responsible parties, electricity suppliers and grid companies.

Please note that the translated versions of the market regulations available on this site are not the applicable versions. Applicable versions are currently only available in Danish (click here to visit our Danish market rules page). 

Rules on trade across borders - transmission rights

The transmission capacity via the 2 Danish-German borders and the internal border between West- and East Denmark (The Great Belt) is administered in co-operation with JAO.EU (Joint Allocation Office S.A.). Authorized market players can reserve capacity for trade over the borders at auctions offered in cooperation with JAO.EU. At the auctions the capacity offered is cross-border/cross-bidding area reservations, and the capacity offered is South/West bound as well as North/East bound. The capacity is offered as physical transmission rights (PTR).

The rules on the transmission capacity are the common European allocation rules for forward capacity allocation, Harmonised Allocation Rules (HAR) and rules for nomination of PTR.
