Network data

All relevant structural data and information on the terranets bw network.

Structural characteristics

The high-pressure pipeline network operated by terranets bw, with operating pressures of up to 80 bar, spans a total length of approximately 3,000 km. Gas is transported via the terranets bw pipeline network to approximately 300 interconnection and off-take points.

The peak load in fiscal year 2025 was recorded on January 14, 2025, between 8:00 a.m. and 9:00 a.m. During this hour, downstream network operators and industrial customers simultaneously withdrew a total of 28.0 MWh/h from terranets bw’s transmission network. The annual energy withdrawn in fiscal year 2025 amounted to 95,684,953 MWh.

We transport exclusively H-grade gas. The calorific value at the entry and exit points ranged between 10.12 kWh/m³N and 11.81 kWh/m³N in the 2025 fiscal year.

Further information on the structural characteristics of the terranets bw network is available for download below.

Calculating technical entry and exit capacities

terranets bw calculates firm, freely allocable capacities (FZK) at entry and exit points on the basis of historical capacity bookings and internal orders according to a statistical procedure. Learn more about this from this PDF document.

Capacity-relevant maintenance measures
We constantly maintain our networks to state-of-the-art technology standards. Here you will find information on current maintenance, repair and integration measures in the network area of terranets bw that can cause capacity restrictions. Shippers or grid operators that may be affected are informed in good time about possible restrictions to their shipping capacity.

Interruptions
Interruptions
In the period 2006 to 2011 as well as 2013, 2014, 2019 untill 2024 shipping in the gas network of terranets bw was possible without restrictions. Despite regional capacity restrictions, interruption of interruptible capacities could be avoided by applying internal switching and subsitution measures.
Below you will find information on interruptions at significant entry and exit points in the network area of terranets bw due to capacity congestion according to section 16 of the Energy Industry Act (EnWG).

Regulation (EU) 2024/1789

According to Regulation (EC) 715/2009 of the European Parliament and of the Council on access to the natural gas transmission systems and in particular Chapter 2 of Annex 1 as amended on 10 November 2010, European transmission system operators are obliged to publish various regularly updated information in a common data format on their websites.

The following table provides an overview of the implemented transparency requirements and shows where the relevant information can be found on our website. Further publications according to Regulation (EU) 2024/1789 Annex 1 Section 3.3 are available at ENTSOG Transparency platform

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 2025 and price list 2026

To justify the amount of the multiplication factors, terranets bw GmbH refers to the Decision of the Federal Network Agency BK9-24/612 (MARGIT 2026).

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 2025 and price list 2026

In Annex I of its Decision BK9-24/612 (MARGIT 2026), 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 2026.

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 2026 terranets bw GmbH refers to the attachment I of MARGIT 2026.
