As a shipper you must purchase capacity in order to transport gas in the transmission system. This gives you the right to send gas into or draw gas out of the system, to have the gas transported into the entry points, out of the exit zone or the transit points, respectively. Capacity in and out of the storage facility and in and out of the GTF is free of charge as of now.

Capacity is purchased in energy units (kWhg) per hour, i.e. gas measured in the maximum number of energy units, which the shipper can send in or draw out of the system at any given hour of the day.

Capacity can be purchased for the following periods of time:

• Days
• Weeks
• Months - both calendar month and 30 days' product
• Years (only at Nybro and Exit Zone - at Ellund and Dragør, please se facts to the right.

Ordering of capacity
You can order capacity in two ways:

1. Online booking procedure
The most comon way of booking is by using the online booking procedure. Before booking, you need to sign an online access agreement. The agreement is appendix 5 to Rules for Gas Transport.

Each shipper must register one or several users through Energinet.dk online. Energinet.dk then provides them with separate or combined authorisations relating to the extend of access needed in the online system.
 
As a shipper you need to make the capacity order using the online booking procedure before 13:30 the day before the first day of the period in which you need the capacity.

2. Manual procedure
Shippers can also order the capacity manually. This is done by sending a capacity order to Energinet.dk by email to anmodning@energinet.dk, as an attached document. The capacity order is appendix 6 to Rules for Gas Transport.

If you use his procedure the order must be received at Energinet.dk 4 banking days before the capacity agreement starts.

• If Energinet.dk receives the capacity order before 09.00 on a banking day we will try to process it before 17.00 two banking days later. Energinet.dk sends an order confirmation by e-mail if the ordered capacity is available and the rules of Rules for Gas Transport are followed.
• Shippers must use the manual procedure according to Rules for Gas Transport clauses 6.7–6.8. Orders for the period commencing on 1 October 2010 received before 0:00 am on Wednesday 1st September 2010 will be rejected.
• The first-come-first-served principle (“FCFS”) in RfG clause 6.2.3 in this case means that all orders received in a certain period will be considered as having been received at the same time. Accordingly, capacity orders received during Wednesday 1st September and Thursday 2nd September 2010 will be considered received at the same time. Scarcity of capacity – if any - will lead to a pro rata reduction of such orders.
• Capacity orders received during Wednesday 1st September 2010 and Thursday 2nd September 2010 for the period commencing on 1st October 2010 will be handled first and equally on 2nd September 2010 cf. RfG 6.7.3. Accordingly, orders placed in this period will give the highest priority in regards to purchase of monthly or yearly capacity commencing on 1st October 2010.
• Cf. the above FCFS interpretation, orders received after Thursday 2nd September 2010 will be handled according to the ordinary FCFS principle. The time of arrival of the order indicates the FCFS order of priority (on a business day by business day basis).
• After Friday 3rd September 2010 the online procedure is available again.
