How are firm and interruptible capacities marketed at cross border points and storages?

The capacities at cross border points and at storages are allocated by an auction procedure. Auctions take place in accordance with European requirements on specific dates and for specific terms. The following dates currently apply for the specified terms:

For firm products

For interruptible products

Interruptible capacities for monthly, quarterly and annual products shall only be offered if the corresponding firm capacity products have been marketed with an auction premium, fully marketed or not offered (article 32 of EU CR 2017/459).

How can capacities be acquired at the network point where the capacity allocation process is not an auction process?

Firm and interruptible capacities at grid points, where capacity is not allocated via auction (industrial customers, production and biogas facilities), are marketed via first-come-first-served (FCFS). At the connection points of this type bookings are possible up to 1 hour before the beginning of the contract.

Are capacities by ONTRAS offered as bundled capacities?

ONTRAS markets firm capacities as bundled capacities only at the cross border point GCP GAZ-SYSTEM/ONTRAS according to NC CAM. Interruptible capacities are not bundled.

Where do you find information about capacities and flows in the ONTRAS grid?

Free and booked capacities as well as physical flows at relevant network points are published in the transparency tool of ONTRAS.

Can interruptible capacities be converted into firm?

Interruptible capacities or capacities with interruptible parts can be upgraded into firm capacities or capacities with less interruptible parts during the bid submission in the auction process on PRISMA or RBP.

Can unbundled capacities been converted into bundled capacities?

At interconnection points unbundled capacities with a duration of a month or more can be converted into bundled capacities during the auction. The conversion function on the respective capacity booking platform can be used for this.

Does ONTRAS offer competing capacities?

No, there are no competing auctions for the ONTRAS grid.

What is the emergency process if bookings on the capacity booking platforms are not possible?

In case of a failure of the booking procedures on the capacity booking platforms, capacities will be allocated in accordance with Section 1 (1) of ONTRAS' Network Access Conditions.

For interconnection points and storage points:

If booking at these points is not possible due to a failure of the booking procedures on the capacity booking platforms, we can provide you with capacity on an interruptible basis. In this case, the booking of capacities is carried out alternatively by submitting an over-nomination, taking into account the nomination lead time (see: Booking of interruptible Within-Day Capacities).
As soon as the above-mentioned failure occurs, ONTRAS will manually activate the over-nomination function. You can track the over-nomination status with the help of a traffic light display in the tab “Booking degree” in our ONTRAS transparency tool.

For connection points to final customers, production points and biogas facilities:

If booking at these points is not possible due to a failure of the booking procedures on the capacity booking platform, please send your capacity booking requests in written form using the form“Request for capacity in case of a platform outage” to capacity@ontras.com and disposition@ontras.com. The capacity allocation outside of the booking platforms is made to the best of one’s ability, but without any guarantee. Capacity requests must be sent at least one hour before the planned transport and according to the regular booking deadline.

In case of bookings that go beyond the following day, we kindly ask you to make the booking at a later date or time.

How can secondary marketing be done at ONTRAS?

In principle, secondary marketing takes place on the capacity booking platforms. The conditions of secondary trading can be found in the GTCs of ONTRAS.

PRISMA: Secondary marketing for network points, which are marketed on PRISMA, shall be done in the section Secondary Trading. More information and details are in the Shipper Hub on PRISMA in the section Secondary Market. 

RBP: Secondary marketing for capacities at GCP GAZ-SYSTEM/ONTRAS shall be done on RBP in the section Secondary Market.

Where can the capacity contract or capacity bookings be viewed? 

To do this, visit the ONTRAS customer portal and select contract explorer. Here you will find all information about your capacity contracts or capacity bookings.

Is the probability of interruption of interruptible capacities published at ONTRAS?

The historical interruption rate can be found in the transparency tool  in the Interruption (historical) tab. A forecast for a future possible interruption of interruptible capacities does not take place.

How is a balancing group transferred to PRISMA or RBP?

Please use the menu item Set up balancing group on the ONTRAS customer portal.

The balancing groups set up by 12 noon can be used for bookings with a run time from the next gas day on the corresponding capacity booking platform. Balancing groups set up afterwards can be used for the bookings that run from the day after next.

PRISMA: After you have successfully entered the data, you will be able to find and select the balancing group on the platform on the same day.

RBP: After you have successfully entered the data, you will be able to find and select the balancing group on the platform on the next working day.

How can the balancing group assignment or inclusion of capacity bookings to a balancing group be changed?

Visit our ONTRAS customer portal and select the balancing group view or capacity contract view.

For this purpose, you are welcome to use our Guideline for the change of the capacity allocation. Please note that the inclusion of short-term capacity bookings (day-ahead or within-day bookings) cannot be adjusted. 

How can firm Within-Day capacities be booked?

Firm Within Day capacities can be booked either via Auction or via First-Come-First-Served (FCFS). In case of a booking via auction, the uniform price algorithm is used. In the course of the FCFS procedure, capacities are allocated according to the chronological order of requests.

Which lead-time has to be considered for firm Within-Day-bookings?

A lead-time of 4 hours has to be considered at cross border connection points as well as at storage points. At connection points to industrial customers, production and biogas facilities there is a lead-time of 1 hour.

How is firm Within-Day capacity charged?

For firm Within-Day capacity, an hourly fee according to the ONTRAS price list is charged. Hereby, the short-term multiplier 2.0 is applied. For storage network points, also seasonal factors are applied.

At which network points can firm Within-Day capacities be booked?

Within-Day capacities (WID) can be booked at all bookable points in the ONTRAS network. These include cross-border interconnection points, connection points to final customers, storage points, production points and biogas facilities.

Can capacities be booked also for the current gas day?

Capacities can also be booked during the day for the current gas day (always until the end of  the current gas day).

How can interruptible Within-Day capacities be booked at the network point, where capacities are allocated via auction?

Interruptible Within-Day capacity at the network points, where capacities are allocated via auction, can be booked by means of an over-nomination.

The precondition is that firm capacities are fully booked and that a balancing group was communicated to ONTRAS.

What is an over-nomination?

An over-nomination is a nomination, which exceeds the corresponding capacity included in the balancing group or sub-balancing account.

If firm capacities of the above mentioned network points in the desired flow direction are fully booked, interruptible within-day capacity can be booked by means of an over-nomination.

If the capacities at the network point in the desired flow direction are not fully booked for the period of over-nomination, a capacity overrun would be created for the difference to the capacity included in the balancing group or sub-balancing account.

How is the customer informed about the possibility of over-nomination?

The information about the current possibility of over-nomination is made available in our Transparency Tool in the "Booking Degree" tab by means of a traffic light display. 

What is the lead time for over-nomination?

The lead time for over-nomination is two hours.

Is it necessary before booking interruptible Within-Day capacities via over-nomination to include capacity into a balancing group?

No, the prior inclusion of capacity into a balancing group is not necessary for the booking of interruptible Within-Day capacities via over-nomination.

What if a customer sends an over-nomination and then sends a re-nomination reducing the values down to zero more than two hours before the first transport hour?

With submission of an over-nomination at a fully booked network point, a capacity contract will be concluded. A re-nomination does not affect this capacity contract.

How is interruptible Within-Day capacity charged?

For interruptible Within-Day capacity (over-nomination), an hourly fee according to the ONTRAS price list is charged. Hereby, the short-term multiplier 2.0 and the discount factor for interruptible capacity are applied. For storage network points, also seasonal factors are applied.

The current tariffs for capacities in the ONTRAS network can be found in the price list in the download area of the ONTRAS website.

Will the tariff be adjusted for long-term capacity bookings as soon as there is a change in the tariffs?

With the entry into force of new tariffs at the beginning of a calendar year, the fees for existing bookings will also be adjusted. If a contract is affected by this adjustment, ONTRAS grants the transport customers the right to terminate the existing capacity contracts in accordance with the general terms and conditions for network access.

What are the preconditions for nomination?

Nominations are possible after a successful communication test. This includes an agreement on the message format and the communication path. Successful nomination processing requires capacities in the balancing group.

How long does it take to successfully implement a communication link?

The implementation of the communication connection can take up to 10 working days.

Which formats does ONTRAS offer for nomination?

What are the deadlines for providing invoicing-relevant data?

ONTRAS always makes every effort to provide the invoicing-relevant data with the greatest care and as early as possible. The respective regulatory deadlines are mandatory for providing invoicing-relevant data.

Does ONTRAS provide gas quality data?

On request, ONTRAS provides benchmarks. This data provides an overview of the gas composition of selected types of gas at entry-points. This helps the users to get information about the gas quality in the respective region. Once a month ONTRAS will publish the gas quality information in the portal.

Is the billing data calibrated?

The gas-quality-reconstruction-system provides billable and calibrated gas properties for different points in the ONTRAS grid, which will be used for the energy quantity determination. The procedure is approved by the Physikalisch Technische Bundesanstalt (PTB) and supervised by the responsible calibration offices. A copy of the certificate can be provided on request.

What actions does ONTRAS take in case of a failure of the data measurement or data retrieval at a network connection point?

According to the requirements of the DVGW worksheet G685, an estimate will replace the data which is missing. As the creation of an estimate for customers with a volatile profile in gas consumption is a complex process, the creation of this estimate will be conducted upon best efforts and abilities and under the consideration of additional information.

How can the user and ONTRAS exchange information about modifications at the measuring device or the meter?

ONTRAS offers the possibility to exchange information about modifications via mail to msb@ontras.com. Furthermore, the user is able to enter the meter readings directly in the ONTRAS portal. However, this data adjustment is only possible in case of control readings. Changes of the master data are not possible.
