Tariff information

Starting point for all tariffs is the annual tariff. Annual tariffs apply to contracts with a flat capacity profile for a period of 12 months. An annual contract may start in any month. Long-term contracts may be concluded in multiples of 12 consecutive months. Contracts may also be concluded for shorter periods of time, for example for a few hours per day, one single day, one single month or several days or months.

A monthly contract always expires on the last day of the calendar month concerned.

Our entry and exit tariffs are mentioned in appendix 1a and 1b of the TSC.

Tariff System

If a shipper books capacity for a period of less than 12 months, the so-called ‘monthly factors’ apply to the tariff. The monthly factor is a percentage of the annual tariff and may differ from month to month.

If a shipper books capacity for a period of less than 12 months, the tariff for the whole period forward transport capacity is booked for, is calculated as follows:

  • The sum of the monthly factors for the individual months (which can never exceed 100%) is multiplied by the annual tariff, or, if this is lower,
  • (81.25% plus 3% of the number of winter months plus 1.5% of the number of spring and autumn months together plus 0.75% of the number of summer months) multiplied by the annual tariff.

For the standard capacity products (quarter, month and day) offered on PRISMA, the correct monthly and daily factors are included in the tariffs.

For backhaul capacity, a monthly factor of 1/12 times the annual tariff applies for each month.

FcFs capacity, both firm and interruptible (if firm is sold out), can be requested for any period as long as it relates to a continuous period and to flat capacity throughout the period. Profile bookings and combined firm and interruptible bookings are not supported by PRISMA. Because the monthly factor system is used, the above-mentioned restrictions can lead to higher costs.

At the shipper’s request, GTS can retrospectively apply the monthly factor system to the combined bookings. Such a request from the shipper will only be granted if the bookings have been made on the same day for the same network point and, of course, in the same direction.

If these requirements have been fulfilled, the capacity is divided into horizontal capacity ranges and the monthly factor system is applied to each individual range. Also see the graph below.

Exceeding capacity

A capacity overshoot, for which a surcharge is applicable and effected, occurs when per day the contractual entry capacity and/or exit capacity is exceeded by more than the operational margin of 2% per hour. Only the highest capacity overshoot per gas day will be charged.

The amount of the surcharge is based on the difference in value between the booked capacity and the actual capacity used multiplied by the valid monthly factor multiplied by the annual network point tariff (transport tariff + balancing tariff + quality conversion tariff valid at the network point concerned).

Neutral gas price

The neutral gas price (NGP) is defined in article 4.1.6.4 of the Transportcode gas LNB and is, among other things, being used for calculating the offline allocations and the settlement of the Linepack Flexibility Services.

The neutral gas price per day is defined as the weighted average of the TTF price for the volume at a gas exchange appointed by the Dutch Ministry of Economic Affairs, for all transactions been executed during the day, the day before and two days before the day of delivery.

As from July 1st 2018 the NGP that is published on the PEGAS Spot Market data and the download page of the Powernext website, will be used by GTS.

Publication of the last final NGP en de temporary (near real time) NGP:

  • The final NGP (‘final’) for the last gas day (D-1) will be available not later than 6.20 at the current gas day (D).
  • The near real time NGP (‘temporary’) for the current gas day (D), the next gas day (D +1) and the following day (D+2) will be update every 15 minutes
  • This data can be found on the website of Powernext

Publication of the historical final neutral gas prices:

  • The final NGP’s of the last 2 months are publicly available
  • This data can be found on the website of Powernext.

Additionally, the last 45 final NGP’s are graphically published on the website of PEGAS.

Until June 27th 2018 the calculation of NGP was executed by ICE ENDEX and could be found by this this link (scroll downwards in the report until you have found the neutral gas price).

Between June 27th 2017 and July 1st 2018 a reference price from PEGAS was used in case the NGP at ICE ENDEX was missing. Until January 1st 2018 this was the TTF DRP index, as from January 1st 2018 this was the TTF EGS index (European Gas Spot Index). The DRP index can be found by this link, the EGS index by this link (scroll downwards to the  European Gas Spot Index and then select TTF).

FAQ

  • ‘Neutral gas price being the most recently published as referred to in the Transport Conditions for Gas, article 4.1.3.8’ means the neutral gas price (as defined in the Transport Conditions for Gas, article 4.1.6.4) as published near real time by PEGAS at 06:00 of the gas day that the bids are being placed.
