ONTRAS offers firm dynamically allocable capacities (DZK) at the point Deutschneudorf for the flow direction exit. If the expected entry pressure of the pipeline 301 in the ONTRAS grid for the following gas business day is at least 65 bar, the use of DZK on a firm freely allocable basis is possible.
The price for DZK capacities at Deutschneudorf is 93 % of the fee for firm capacities.

The requests for capacities have to submit until 6 p.m. on the gas business day before the planned gas transport.

At which network point are firm Within-Day capacities offered?

Within-Day capacities are marketed at all bookable point in the ONTRAS grid. These are cross border and market area connection points, connection points to industrial customers, storage points, production and biogas facilities.

Are Within-Day capacities available for the current gas business day?

The capacity booking for the current gas day are possible at all bookable points.

A lead-time of 4 hours has to be considered at cross border and market area connection points. At storage points, the lead-time is 3 hours and at connection points to industrial customers, production and biogas facilities there is a lead-time of 1 hour. 

What is the price for Within-Day capacities?

The price for Within-Day capacities is the daily fee multiplied by the short-term factor 1.4 in proportion to the yearly fee according to BEATE.

How are over-nominations and capacity overruns charged?

  • Network point not fully booked (firm) and customer nominates more than booked - capacity overrun
  • Capacity overrun: Regular daily charge (including the short-term multiplier) for the overrun amount plus three times the daily charge for the difference between the used capacities and the included capacities in a balancing group (based on Sec. 11 GT&C)
  • Network point fully booked (firm) and customer nominates more than booked - Within-Day overnomination
  • Within-Day overnomination: Daily charge for interruptible capacities (including the short-term multiplier)
  • Network point fully booked (firm) during the day and customer nominates more than booked 
    - capacity overrun when network point is not fully booked
    - Within-Day overnomination when network point is fully booked
  • Capacity overrun: Regular daily charge (including the short-term multiplier) for the overrun amount plus three times the daily charge for the difference between the used capacities and the included capacities in a balancing group (based on Sec. 11 GT&C)
    + Within-Day overnomination: Daily charge for interruptible capacities

 

 

How is the customer informed about the possibility to over-nominate?

The information about free firm capacities is published in the transparency tool on the ONTRAS website as well as on PRISMA.

What is the lead time for over-nomination?

The lead time for over-nomination is two hours.

Is the inclusion of the booked point into a balancing group required?

For an over-nomination the following preconditions need to be considered:
Firm capacities at the network point are fully booked,
the grid point that you would like to over-nominate needs to be included into a balancing group in the relevant direction.

When is over-nomination possible?

Only when the network point is fully booked, over-nomination is possible after the Day-Ahead auction.

What if a customer sends an over-nomination and then sends a renomination 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 renominiation does not affect this capacity contract.

The latest price list is published in the download area on ONTRAS website. 

Do the fees for long term bookings retrospectively change once new tariffs are published?

When new fees come into force, these new fees are also applicable to existing bookings.
In accordance with Sec. 25 para 4 of the GT&Cs, ONTRAS grants to the customer the right to terminate the existing capacity contract if it is affected by this adjustment.

Are secondary trades affected by the BEATE regulation?

With the assignment of secondary deals the short term multipliers are applicable. For example, if a quarterly product is bought via secondary trade out of a yearly contract, the multiplier of 1.1 will be applied for the quarterly product. The original yearly contract still has the multiplier of 1.

Due to the contractual relationship between the shipper and the transmission system operator, the short term multiplier does not apply for transfer of use.

Invoicing and technical quantity evaluation

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.
