Plant operators are entitled against the grid operator to the connection of their plants to the grid. Electricity from renewable sources is not granted priority connection.

Procedure

Process flow

The procedural steps are not specified by law. According to Energinet.dk, the procedure to be applied depends on the capacity of a given plant and on the voltage of the grid this plant will be connected to. 

1) Connection of plants with a capacity of up to 11 kW: 

  • Application for connection. The installer of the plant submits the application for connection to the grid operator.
  • Installation of the plant.
  • Agreement on connection to and use of the grid with the grid operator. 
  • Registration of the plant.
  • Installation of required meters. 
  • Submission of documents to the grid operator. The plant operator must submit the required information (general and technical specifications) to the grid operator. The grid operator then forwards these documents to Energinet.dk. 
  • Permission to operate. The grid operator gives the plant operator permission to operate. 
  • Connection to the grid. A plant is connected to the grid after the plant operator has been given permission to operate. 

2) Connection of wind energy plants to the 100 kV grid: 

  • Application for connection to and use of the grid. The plant operator applies to the grid operator for connection to and use of the grid. 
  • Assignment of connection point. The grid operator assigns a connection point to the plant operator and determines the required voltage level. 
  • Agreement on connection to and use of the grid with the grid operator. 
  • Registration of the wind or solar energy plant. 
  • Installation of the wind or solar energy plant. 
  • Installation of required meters. 
  • Agreement with a licensed expert who shall be responsible for balancing the output of the plant.
  • Submission of documents to the grid operator. The plant operator must submit the required information (general and technical specifications) to The grid operator. The grid operator then forwards these documents to Energinet.dk. 
  • Permission to operate. The grid operator gives the plant operator permission to operate. 
  • Connection to the grid. A plant is connected to the grid after the plant operator has been given permission to operate. 

3) Connection of wind farms to the > 100 kV grid: 

  • Application for connection. A plant operator shall apply to the transmission grid operator for connection and submit the necessary permits and licences together with the application. 
  • Agreement on connection with the grid operator. 
  • Registration of the wind farm. 
  • Installation of the wind farm. 
  • The wind farm operator must submit the documents required for a plant test to Energinet.dk within 3 months after the wind farm was put into operation. 
  • Installation of required meters. 
  • Agreement with a licensed expert who shall be responsible for balancing the output of the plants. 
  • Commissioning of the plants and commissioning report. 
  • When the plants have been commissioned, the grid operator will give the plant operator temporary permission to operate and submit the technical documents (commissioning report and permission to operate) to Energinet.dk. 
  • Energinet.dk then confirms the temporary permission to operate and approves the documents. 
  • The grid operator gives the plant operator final permission to operate.
  • Connection to the grid. A plant is connected to the grid after the plant operator has been given permission to operate. 

Any plant must meet the technical requirements set by the Ministry for Energy, Utilities and Climate (§ 26 Act 1009/2018).

The grid operator is obliged to connect any wind power plant that fulfils the grid connection requirements (§ 2 par. 2 BKK 864/2018).

Deadlines

No deadlines are specified for the connection procedure.

Obligation to inform

Plant operators are obliged to submit the general and technical documents required to the grid operator or the Danish Energy Agency. Apart from that, the owner of a wind turbine is, at any given time, obliged to provide any information necessary for the implementation of grid connection to the Danish energy Agency (§ 11 BEK 864/2018) 

The grid operator is obliged to provide any owner of a wind plant requesting grid connection with all the necessary information including:

  • a detailed estimate of all expenses for connection; 
  • a reasonable and precise timetable for processing the grid connection application and 
  • a reasonable indicative timetable for grid connection itself (§ 10 BEK 864/2018).

Priority to renewable energy

  • Priority to renewable energy
  • Non-discrimination

Plants shall be connected according to non-discriminatory procedures (§ 24 par. 2 Act 1009/2018).

Distribution of costs

Grid operator

The cost of connecting a wind or solar energy plant is borne by the plant owner and the transmission grid operator and the Ministry of Energy, Utility and Climate (§ 30 Act 1194/2018).

Plant operator

The cost of connecting a plant to the grid is borne by the plant operator. The costs a plant operator has to bear shall not exceed the costs that would be incurred if his plant was connected to the 10-20 kV grid. This rule applies even if the grid operator chooses to connect the plant to a different grid. All other costs, including the expansion and upgrade of the grid, shall be borne by the grid operator (§ 67 Act 1194/2018).
