Cross-border heat supply moves closer to reality
Industrielle Werke Basel (IWB) and the municipal utilities of the German town of Weil am Rhein are looking into a joint heating network. The technically feasible project could supply heat from Basel to Weil from mid-2028.
The Basel-based utility company IWB and Stadtwerke Weil am Rhein are examining the options for a joint, cross-border heat supply. A feasibility study has already demonstrated the technical feasibility of supplying the city in the German state of Baden-Württemberg with heat from Basel from mid-2028, according to a press release.
The feasibility study has been running since May 2025 and the companies have been sounding out potential consumers for their interest in such a heating network since March 2026. The heat required in the area between the Rhine and the A5 motorway would be supplied by IWB, which should already be 80 percent CO2-neutral by the time of delivery. Once the results are available by the middle of the year, a decision will be made on realisation and possible investment plans, according to the press release.
