Become a customer

You have to become a registered storage customer by entering into a Storage Customer Agreement with Gas Storage Denmark before you can make use of our storage services.

You can find the Storage Customer Agreement in Appendix 1 to GTCGS (General Terms & Conditions Gas Storage)).

  • Credit details and credit limit are needed before signing the Storage Customer Agreement. The required documentation is your latest financial highlights and all subsequent interim financial announcements as well as indication of the credit limit you request.
  • In case Gas Storage Denmark requires that a player should provide security, this must be effected before the player can act as a storage customer. When the credit framework has been arranged, the player will receive two copies of the agreement to be signed and returned to Gas Storage Denmark.
