Security of supply, also at peak load times

To ensure a secure supply of energy also in times of increasing demand – this is our most important task and the reason for terranets bw to continuously expand its gas network. For Hesse, the Gas Network Development Plan (Gas NDP; German: NEP Gas) foresees the construction of a pipeline from Wirtheim to Lampertheim, the "Spessart-Odenwald pipeline" (SPO).

The Spessart-Odenwald pipeline will sustainably increase the security of supply both for gas and electricity, also during peak loads. It is planned that the pipeline be commissioned for gas transmission from 2027.
Additionally: terranets bw is building the "Spessart-Odenwald pipeline" as a flexible energy grid for the future. The Spessart-Odenwald pipeline will be "H2-ready", i.e. it will also be designed for the transmission of hydrogen.

Planning and dialogue

Nationwide development planning: Spessart-Odenwald pipeline secures energy supply as demand increases

The "Spessart-Odenwald Pipeline – SPO" is one of the measures to strengthen the gas transmission system anchored in the Gas Network Development Plan 2020-2030 (Gas NDP). It will connect to the existing gas pipeline network of terranets bw and extend 115 kilometres to Lampertheim. Commissioning is planned for 2027. In the future, the Spessart-Odenwald pipeline will be able to ship hydrogen in addition to climate-neutral green gases and is being designed for this purpose today.

Development requirements are coordinated across Germany in the Gas Network Development Plan (Gas NDP). This plan sets out all the measures necessary in the next ten years to ensure safe, secure and reliable network operation – for optimising, strengthening and expanding the network in line with demand as well as for guaranteeing security of supply. These measures are reviewed by the Federal Network Agency and – after consulting the public – confirmed. This process means that terranets bw is then officially commissioned to implement the development measures.

Commencement of planning: First assessments

A feasibility study for the Spessart-Odenwald pipeline has already been completed. The result of the study is: the Spessart-Odenwald pipeline is to run predominantly along the existing "MIDAL” gas transmission pipeline (German: "Mitte-Deutschland-Anbindungsleitung”). 

The distance between the Spessart-Odenwald pipeline and the existing MIDAL pipeline can vary along the course of the pipeline. At a few places, it is also possible that the route of the planned Spessart-Odenwald pipeline will deviate – for technical reasons, for example, or because nature conservation, existing industrial sites or residential areas make it necessary. 

From summer 2022, terranets bw will begin with assessments on the detailed planning of the pipeline route. In addition to ground properties, also the natural environment and nature along the pipeline route will be analysed in the coming months. Based on the results of these analyses, terranets bw will then draw up a proposal for the course of the Spessart-Odenwald pipeline in detail, plot-by-plot.

Dialogue: Finding the best solution for the region together

The planning team assesses very carefully: What is the best possible solution for the region? Where can the planned pipeline route be further improved? And how can the implementation be as compatible as possible? And especially important: open exchange and transparent processes.

terranets bw therefore regularly informs representatives of the region and the affected communities, authorities and interest groups as well as citizens about the current planning status and provides targeted offers for information and exchange during the individual project phases.

Approval and construction preparation: What happens up to the time of commissioning?

terranets bw plans to submit the planning application for constructing and operating the Spessart-Odenwald pipeline to the Darmstadt Regional Council in 2024. The planning approval procedure then begins, whereby the competent authority weighs up all the public and private concerns affected by the planning. Public interest groups and affected parties are able to submit their comments. With the planning approval decision, the authority approves the detailed pipeline route application.

Parallel to the approval procedure, terranets bw begins with acquiring the rights of way and pipeline rights for the Spessart-Odenwald pipeline. From 2025, preparations then begin for constructing the pipeline. Construction itself is planned to begin in 2026. Commissioning is scheduled for 2027.

Questions and answers

  • Why is it necessary to develop the gas transmission system?

    Why is it necessary to develop the gas transmission system?

    To ensure that the energy transition is implemented successfully and to guarantee a secure energy supply also during the phase-out of nuclear and coal, it is necessary to have a powerful gas transmission system – for local suppliers in the region, for industry and commerce and for system stability in the electricity grid, which must be supported by modern gas-fired power stations. terranets bw is responsible for operating and expanding its gas transmission system. According to sections 1 and 11 of the Energy Industry Act (German: EnWG), terranets bw is obliged to operate a safe, secure, reliable and powerful gas transmission system and to develop the network as demand for gas shipping capacity continuously increases.

    Development requirements are coordinated across Germany in the Gas Network Development Plan (Gas NDP). This plan sets out all the measures necessary in the next ten years to ensure safe, secure and reliable network operation – for optimising, strengthening and expanding the network in line with demand as well as for guaranteeing security of supply. These measures are reviewed by the Federal Network Agency and – after consulting the public – confirmed. This process means that terranets bw is officially commissioned to implement the development measures.

  • Why is the Spessart-Odenwald pipeline important?

    Why is the Spessart-Odenwald pipeline important?

    Gas pipelines such as the Spessart-Odenwald pipeline play an indispensable role in transforming the energy infrastructure. Data provided to terranets bw by distribution system operators, municipal utilities, modern power station sites and industry is unambiguous: by the year 2030, demand for natural gas shipping capacity in the terranets bw supply area will grow by 24 percent in order to be able to secure the agreed phase-out of nuclear energy and coal in the region. In order to be able to ship more gas at the same time, terranets bw must develop its gas transmission system. In the future, the Spessart-Odenwald pipeline will be able to ship climate-neutral, green gases and hydrogen. The pipeline is being designed for this purpose today.

  • Why do we need natural gas? Do we not want to be climate-neutral as soon as possible?

    Why do we need natural gas? Do we not want to be climate-neutral as soon as possible?

    Using natural gas is associated with fewer emissions than other fossil fuels, such as lignite or anthracite. Natural gas secures an efficient and reliable supply of energy amidst the transformation of our energy systems. As a source of energy, natural gas is an important companion on our way to a complete energy supply based on renewable energy. It stabilises the supply of energy, also in times of low wind and little sunshine – and supports the rapid phase-out of nuclear energy and coal.

  • Who is responsible for constructing and operating the Spessart-Odenwald pipeline?

    Who is responsible for constructing and operating the Spessart-Odenwald pipeline?

    terranets bw, which is located in Frankfurt and Stuttgart, is responsible for constructing the Spessart-Odenwald pipeline. The company is responsible for providing a reliable supply of electricity and heat in the region. terranets bw was founded 60 years ago. Some successful building projects completed by terranets bw are, for example, expansion of the gas compressor station in Scharenstetten near Ulm and construction of the new Nordschwarzwald pipeline. The total length of pipeline network operated by terranets bw is currently around 2,700 kilometres.

  • What rights and obligations does terranets bw have in the use of land?

    What rights and obligations does terranets bw have in the use of land?

    In order to use land for constructing pipeline routes, pipeline rights in the form of permission agreements must be established with all landowners and users of the land who are affected. A limited personal easement that must be granted by the landowners secures this permission in the land registry. The landowners receive in return an one-off payment. This payment depends among other things on the size of the protective strip along the pipeline. Calculations are based on defined compensation rates. terranets bw also pays for any loss of farming income or other damages that can result from works in connection with laying the pipeline.

  • What restrictions are to be expected by the farming community?

    What restrictions are to be expected by the farming community?

    Agricultural land will be temporarily occupied by the working strip when constructing the pipeline. Areas along both sides of the working strip can continue to be used during the construction phase. terranets bw minimises harvest disruptions as far as possible and compensates such disruptions if necessary based on defined rates. After usage by terranets bw, the land is recultivated so that there are no significant restrictions on agricultural use.
