Big update: Construction work on the district heating pipeline in Ludwigshafen-West!

Important construction work on the district heating pipeline will take place in Ludwigshafen-West on Wednesday, October 29, 2025. TWL Netze GmbH awarded the contracts, which will be implemented by Diringer & Scheidel. The aim of this work, which will be carried out from 7 a.m. to 5:30 p.m., is to ensure the long-term reliable district heating supply in the region. The project is considered part of an ongoing process to modernize the district heating infrastructure in order to adapt it to current standards. However, during the construction work there may be interruptions in the district heating supply, which could pose challenges for the affected residents.

It all sounds like a small construction site, right? But the work on the district heating network is just one piece of the mosaic in a larger puzzle. In addition to the local measures, the heat transition in the Rhine-Neckar metropolitan region is a forward-looking project. The Stadtwerke Frankenthal, the Technical Works Ludwigshafen (TWL) and BASF work closely together to achieve a CO2-free and cost-effective district heating supply for households in Ludwigshafen and Frankenthal. The planned large-scale heat pump, which is to be built on the site of the BASF sewage treatment plant, will have a heating output of up to 50 megawatts and supply around 18,000 households with climate-neutral heat.

Together for the future of heat supply

The project aims to reduce CO2 emissions by approximately 60,000 tons per year and uses waste heat from the industrial wastewater stream from the BASF wastewater treatment plant. Ludwigshafen and Frankenthal are connected via an approximately 10 kilometer long district heating route. The goal is to offer at least 50% of piped heat in a climate-neutral manner by 2030, and even 80% from renewable energies or unavoidable waste heat by 2040. By 2045, all heating networks in Germany should be completely climate-neutral, and the support from BEW funding plays a central role in this.

In order to meet the challenge of heat supply, it is important to take into account the political framework that will facilitate the transition to renewable energies. According to the Federal Environment Agency, the operation of buildings in Germany causes around 35% of final energy consumption and contributes 30% to CO2 emissions. A sustainable heat supply is therefore crucial, with innovative processes such as serial renovations, the digitalization of buildings and energy-saving renovations helping to reduce consumption.

A look into the future

If the project becomes operational in 2027, it could not only revolutionize local energy supplies, but also serve as a model for other regions. It shows how regional cooperation and commitment to sustainable energy can go hand in hand. Finally, the social dimension must also be taken into account in climate policy, particularly for low-income households who may have difficulty heating their homes adequately.

In summary, it can be said that the construction work on the district heating pipeline in Ludwigshafen is not only intended to improve the quality of the energy supply, but is also a step towards a more environmentally friendly future. The heat transition is underway, and the commitment of regional actors is a sign of the necessity and urgency of this transformation.
