Suppliers
Suppliers deliver gas to customers in the regional grid of the Distribution System Operators (DSO) in the various customer categories (large-scale user and small-scale user).
Suppliers also deliver gas to directly connected parties who are connected to the Gasunie Transport Services (GTS) grid.
If a market party wants to become active as a supplier in the distribution network, it has to register with EDSN via Partners in Energie. If the market party also wants to become active as a supplier for small-scale users (including households), a supply license also has to be obtained from ACM.
EDSN sends a message to market parties, including GTS, when a supplier has completed the registration process. GTS will then request the supplier to fill in a Supplier Registration form in order to register the supplier with GTS. This is necessary to ensure correct messaging in which the EAN code of the supplier is an essential part and for the delivery to small-scale users in the distribution network, for the invoicing of Peak Supply.
The supplier always has a relation with a shipper. The shipper buys and delivers the gas to the supplier. When a market party wants to become active as a supplier for directly connected parties to the GTS grid, this market party has to register at GTS as a supplier.

Peak Supply
In the ‘Besluit Leveringszekerheid Gas’ laid down in the Gas Act of 13th April 2004 it is stated that Gasunie Transport Services (GTS) is responsible for the services of Peak Supply. This implies that GTS accommodates the gas transport and the gas transport capacity to Suppliers that is needed to supply small consumers (G1A and G2A) at temperatures below -9°C. The costs for the accommodation are invoiced by GTS on a monthly basis to the licensed suppliers (‘vergunninghouders’) that can deliver to small-scale users.
Actual Peak Supply is the case when the effective daily temperature is below -9 ºC. For this actual Peak Supply, licensed suppliers who deliver to small-scale users in the distribution network (G1A, G2A), will be invoiced separately.
The invoices for Peak Supply are posted on the GTS online customer portal Gasport where the invoices can be downloaded. Access to Gasport can be requested by filling in the form Online Services – Gasport and B2B.
