Booking of interruptible WD capacity
Additionally, interruptible within-day capacities may be booked through a process of overnomination. The booking of interruptible within-day capacities is only possible through overnomination, if the firm capacity with the exception of restricted allocable capacity (bFZK), at the corresponding booking point has already been completely traded or if only interruptible capacities are available for trading.
In addition, shippers can submit a nomination for a balancing group even if no capacities have been included there before.
Emergency Process for Capacity Booking Requests
In the case of technical issues with PRISMA or its connected systems, GRTgaz Deutschland offers overnomination as an emergency process for trading daily products or within-day auctions at the border and market area crossing points.

Capacity Products
As an efficient and reliable partner in gas transport, GRTgaz Deutschland plays an innovative role in the development of new capacity products as optimised solutions for the customer. One example of this is the product DZK (Dynamically Allocable Capacity).
GRTgaz Deutschland offers the following capacity products:
Freely allocable capacities allow firm transports in the whole market area as well as access to the Virtual Trading Point of NCG.
Conditionally firm freely allocable capacities are, in principle, both firm and freely allocable within the whole market area, and have access to the Virtual Trading Point of NCG. They only become interruptible capacities if the physical northbound flow into the system of Open Grid Europe at the stations Rimpar and Gernsheim both exceeds a particular limit, defined by Open Grid Europe, due to the current nominations within the market area, and if the forecast of the average daily temperature for the previous day at the meteorological station at Essen is above zero degrees centigrade.
Dynamically allocable capacities (DZK) are firm capacities whose free allocation is subject to usage restrictions. DZK are firm capacities if they are used without access to the virtual trading point and exclusively for the purpose of carrying out a balanced transport between entry and exit points.
To balance your DZK capacities, you need a DZK balancing group to which one or more routes can be assigned. However, only one Exit point can be assigned to a DZK balancing group, but several Entry points. If you plan to use the reverse routes as well, you will need more DZK balancing groups depending on how many exit points you plan to use.
Point combinations (routes) offered at the virtual interconnection points (VIP):
- Entry VIP Waidhaus-NCG to Exit VIP France-Germany
- Entry VIP Oberkappel-NCG to Exit VIP France-Germany
In case of renomination restriction, the reverse combinations will also be offered:
- Entry VIP France-Germany to Exit VIP Waidhaus-NCG
- Entry VIP France-Germany to Exit VIP Oberkappel-NCG
Interruptible capacities allow transport within the whole market area as well as an access to the Virtual Trading Point of NCG on an interruptible basis.

Application of multipliers for non-yearly capacity products
The BNetzA’s MARGIT decision provides that, in converting yearly standard capacity products into non-yearly standard capacity products (‚non-yearly products‘), a multiplier is to be applied at all interconnection points.
The fee for non-yearly products is calculated by dividing the relevant annual fee by 365 and then multiplying it with the duration of the respective product (in days) and the relevant multiplier to be identified as follows:
Product | Multiplier |
Within-day | 2 |
Daily (duration 1-27 days) | 1.4 |
Monthly (duration 28-89 days) | 1.25 |
Quarterly (duration 90-365 days) | 1.1 |
