Booking capacity

Gasunie markets entry and exit capacity at border/market area transition points, final consumer connection points, biogas plants and storage interconnection points. Sales are primarily handled via PRISMA, an online EU capacity booking platform. The shippers can use this platform to easily and flexibly organize their gas transport.

PRISMA - booking online capacity

Gasunie's Entry and exit capacity can easily be booked via PRISMA Primary, an online platform established by EU TSO's. Depending on the type of transport, capacity can be booked via auctions or using the "first come- first served"(FCFS) principle. This implies that the first party booking capacity is provided with the available free capacity.

All capacities except interruptible capacity  that is transported via Market Area Transfer Points (MTP) and the Border Crossing Points (BIPs) are handled viaauction processes. The auctions include capacity products for different periods. Like, annual, quarterly, monthly and daily products, each with its own auction date. Since November 2015, hourly capacities are also available at these transition points. This creates maximum flexibility for gas traders. And, the more cost-effective interruptible capacities have also been auctioned since that date.

Capacity for end consumers such as industrial companies, gas-fired power stations, storage facilities and entry from production, LNG and biogas plants are booked via the FCFS procedure. There are no fixed booking times. However, shippers must observe lead times. A change in the booking of entry and exit capacity at storage points is provided for 2018.

The current applicable tariffs for booking capacity at Gasunie's entry and exit points are published in our price sheet.

When booking entry capacity at one of our entry points, shipper receive the right to enter a specific quantity of gas per hour at the booked entry point into Gasunie's transport network. Accordingly, a Shipper, that booked an exit capacity at a Gasunie exit point, has the right to withdraw a specific quantity of gas per hour at that booked exit point. The prerequisite for the use of booked entry and / or exit capacity is the transfer of the booked entry and / or exit point into a balancing group at the TSO of the market area GASPOOL.

Gasunie accepts gas that is entered at the feed-in points and makes it available in the customer's allocated balancing group. Likewise, gas that exits our system is taken from the allocated balancing group.

Entry and exit capacity can also be booked on a firm or interruptible basis. Interruptible capacity is capacity that can be booked by a shipper on an interruptible basis in accordance with the terms and conditions of Gasunie. The use of this interruptible capacity can be interrupted by the network operator.


Holders of interruptible capacity at market area or cross-border points may bid at a fixed auction to convert interruptible capacity into fixed. The shipper can further also determine, whether the interruptible capacity should be replaced in full or on a pro rata basis by fixed capacity. Both the proportionate conversion and the conversion of multiple interruptible capacities can be proceeded with. Interruptible capacity at all other entry and exit points that are not offered in an auction (e.g. capacity at storage points) may be converted during fixed capacity booking. Further information on conversion can be found in the Gasunie Terms and Conditions.

The cooperation agreement

TSO's have committed to form cross network market area's trough cooperation in the "Cooperation Agreement between the operators of gas supply networks located in Germany (KoV)". The goal is to integrate the downstream regional and municipal networks and to cooperate as far as technically possible and economically reasonable. This cooperation is necessary in order to enable shippers to handle the transport of gas via several networks interconnected in a market area through interconnection points by means of only one entry and one exit contract. The cooperation agreement including the annexes and guidelines is updated regularly and is available.

With the introduction of the "Basic Model of Compensation and Balancing Rules in the Gas Sector" (GABi Gas and GABi 2.0), "Determination Procedure for Gas Capacity Regulations" (KARLA and KARLA 1.1) by the Federal Network Agency and further adaptation due to national or European changes, it was necessary to adjust the KoV in accordance with the stipulations and rules that were provided.

The respective changes apply to both existing and new contracts.
