EXAMPLES OF FIRM CAPACITY PRODUCTS WITH ‘CONDITIONS’
Firm capacity product
with ‘conditions’ Explanation
TSOs offering a given firm capacity product
with ‘conditions’
Restrictedly
usable firm
Capacity that ensures firm freely allocable network
access within an entry-exit-system on a firm basis
within certain gas flows, within certain tempera-
ture ranges and/or entry-exit-system load/demand;
Access to the VTP included
Thyssengas, Fluxys TENP, GRTgaz Deutschland,
GTG Nord, OGE
(called ‘bFZK’ in Germany – used on entry points to
control local distribution of incoming flows;
called ‘TAK’ if used at network points to storage
facilities)
Creos
Restrictedly
allocable firm
Restrictedly allocable capacity ensures the injec-
tion of gas on a firm basis at entry point(s) and the
withdrawal of gas at explicitly dedicated exit
point(s) and vice versa on a firm basis
Can use this capacity with ‘explicitly dedicated
exit point(s)’, but not in combination with other
exit/entry points or VTP
bayernets, Fluxys TENP, OGE, GUD
(called ‘BZK’ in Germany; if the distance between
the entry and exit points is short, the product may
be called ‘Shorthaul’)
Fluxys Belgium (called ‘Wheeling and OCUC –
Operational Capacity Usages Commitments’)6)
GTS7)
Dynamically
allocable firm
Dynamically allocable capacity ensures the injec-
tion of gas on a firm basis at entry point(s) and the
withdrawal of gas at explicitly dedicated exit
point(s) and vice versa on a firm basis
Functions as interruptible capacity in combination
with the VTP and all exit/entry point(s) other than
‘explicitly dedicated exit points’
GASCADE, GRTgaz Deutschland, GCA, TAG, NEL,
GTG Nord, Fluxys Deutschland, Lubmin-Brandov
Gastransport, ONTRAS
(called ‘DZK’ in Germany)
Table 24: Examples of firm capacity products with ‘conditions’
1) Definition 55 of the Gas Market Code:
2) Section 3.2, Attachment A:
3) GasNZV § 3, Abs. 3:
4)
5) Article 2.1.6 of the Transmission Code, description of shorthaul:
6) Wheeling is shorthaul over a zero distance (two flanges on the same physical location) to allow shippers a U-turn on the
Dutch or Belgium border. ‘OCUC’ means an entry or exit service subject to an Operational Capacity Usage Commitment
(OCUC), which is an operational agreement between network user and TSO in the framework of the proactive congestion
management policy.
7) GTS offers a product called shorthaul on a FCFS basis. Shorthaul is different from restricted allocable firm capacity,
as shorthaul gives access to exactly one physical exit point using flange capacity that exceeds the available technical
capacity. Shorthaul does not limit the amount of available technical capacity on auction at any network point in the GTS
transmission network. The feasibility of shorthaul depends on the distance between the entry and the exit point, the
amount of capacity and the duration of the contract. These parameters determine the shorthaul tariff.
