All important information for
our gas customers

The terranets bw gas network: 3,000 km.
A reliable supplier.

The terranets bw gas network With a length of approximately 3,000 kilometers, the terranets bw gas transmission network is a central component of the energy infrastructure in southwestern Germany. It is connected to national and international partner networks via numerous feed-in and interconnection points and reliably supplies distribution network operators and industrial customers with natural gas. Four underground gas storage facilities further ensure supply and system stability—one of which is uniquely and fully integrated into our transmission network.

Maintenance measures affecting capacity
Wir halten unsere Netze immer auf dem aktuellsten Stand der Technik. Informieren Sie sich über aktuelle Wartungs-, Instandhaltungs- und Einbindungsmaßnahmen im Netzgebiet der terranets bw, die Kapazitätseinschränkungen zur Folge haben können. Davon betroffene Transportkunden oder Netzbetreiber werden rechtzeitig über mögliche Einschränkungen ihrer Transportkapazität informiert.

Im Zeitraum 2006 bis 2011 sowie 2013, 2014, 2019 und 2020 war der Transport im Gasnetz der terranets bw uneingeschränkt möglich. Trotz regionaler Kapazitätseinschränkungen konnte durch den Einsatz interner Schalt- und Ersatzmaßnahmen die Unterbrechung der unterbrechbaren Kapazitäten vermieden werden.

Regulation (EU) 2017/460, Art. 29

According to Art. 29 of Commission Regulation (EU) 2017/460 of 16 March 2017 establishing a network code on harmonised transmission tariff structures, European transmission system operators are obliged to publish information prior to the annual auction.

The following table provides an overview of the implemented transparency requirements and shows where the relevant information can be found on our website.

Art. 29 (a)
Information on standard capacity products for binding capacity (reserve prices, multiplication factors, seasonal factors, etc.)

Please see price list 2026 and price list 2027

To justify the amount of the multiplication factors, terranets bw GmbH refers to the Decision of the Federal Network Agency BK9-25/612 (MARGIT 2027).

Art. 29 (b)
Information on standard capacity products for interruptible capacity
(Reserve prices and an evaluation of the probability of an interruption)

Please see price list 2026 and price list 2027

In Annex I of its Decision BK9-25/612 (MARGIT 2027), the Federal Network Agency determined the amount of the discount for interruptible capacity to be applied at the interconnection points. The methodology to calculate these discounts is described in section 7 of the decision of MARGIT 2027.

The methodology to calculate discounts for interruptible capacity of storage points is specified in the decision of the BNetzA BK9-18/608 (Decision ‘BEATE 2.0’, chapter 3.2). The probability of interruption Pro according to decision BK9-18/608 (Decision ‘BEATE 2.0’) is derived from the data of the last three gas business years of the respective entry and exit point according to the following formula:

(K)u describes the maximum interrupted interruptible capacity on day t, (K)v describes the interruptible capacity marketed on day t and S the safety margin, which represents the forecast uncertainty. The probability of interruption is rounded up to full percentage. The applicable discount corresponds to the probability of interruption and is independent of the product duration.

According to decision BK9-24/608 (‘BEATE 2.1’), the safety margin of S=10% is again valid for all non-interconnection points, whereas the safety margin at non-interconnection points in the H-gas network was set to S=20% from 01/10/2021 to 31/12/2025.

The data to calculate the discount (sales and interruption of interruptible capacity) can be obtained at the ENTSOG transparency platform.

There has been no interruption at the points according to BEATE 2.0.

For the discount for interruptible capacity in the calendar year 2027 terranets bw GmbH refers to the attachment I of MARGIT 2027.

Regulation (EU) 2017/460, Art. 30
Regulation (EU) 2017/460, Art. 30
According to Art. 30 of Commission Regulation (EU) 2017/460 of 16 March establishing a network code on harmonised transmission tariff structures, European transmission system operators are obliged to publish information prior to the tariff period.
Publication obligations according to Art. 30 Regulation (EU) 2017/460 (NC TAR) (as of: 28.11.2025)
Annex for publication obligations to Art. 30 (Excel-file) (as of: 28.11.2025)

Pursuant to Article 19(1) of Regulation (EU) 2024/1789 of the European Parliament and of the Council of 13 June 2024, European transmission system operators are required to publish information on the determination of allowable revenues or the methods, parameters and values used to determine the target revenues of transmission system operators.
