When a shipper has commercially injected bio natural gas into the transmission system by making nominations to a certain BNG entry point, shippers in the entire Danish system may trade the gas in all existing points on the same terms as any other natural gas.
15 per cent free balance margin
It is a general requirement that the shippers must be in balance. As Danish con-sumption is difficult to predict with any degree of precision, it is therefore diffi-cult for shippers to precisely balance the volume of gas transported through the network for consumption in Denmark, ie exit zone Denmark.
Where the BNG entry point is concerned, predicting the exact amount of bio natural gas that is produced and injected into the system is considered to be even more difficult for shippers. This is the reason why shippers are initially allocated a free balance margin of 15 per cent of the capacity ordered in the BNG entry point. The allocation is based on the exact measured value.
The rules regarding balance for shippers with capacity in the BNG entry point also apply to all other entry points.
Tariffs
The tariff that applies to the BNG exit point is the same as the one that applies to the other entry and exit points.
No distinction is made as to whether a physical or commercial/virtual transport actually takes place. Both types of transport make it possible for shippers to use the Danish gas transmission system for trading gas. And it is the system as a whole and the possibilities it offers for providing capacity in all points that form the basis of tariffing. The duration of the actual transport is not taken into ac-count. Because of the 'stamp principle' all transport routes thus cost the same.
Players wanting to inject bio natural gas into the Danish natural gas transmis-sion system with a view to trading it in Denmark and across borders must therefore order capacity and pay for accessing the system.
