  • Balance responsible party: Electricity suppliers must conclude an agreement with a balance responsible market player.
  • Grid Company: Electricity suppliers must conclude an agreement with the specific grid company to access its grid. Danish Energy has prepared a standard agreement that gas suppliers are welcome to use. The agreement covers all the grid companies available to electricity suppliers in Denmark.
  • Payment guarantee: Electricity suppliers must provide a bank guarantee or similar security for the payments received from customers on Energinet’s behalf. 

* New electricity suppliers can in the start-up phase access DataHub through a DataHub market portal. Note that the amount of data messages quickly can become extensive and therefore difficult to handle manually. Instead we therefore recommend B2B communication.
