Geothermal heating project in Michaelibad, Germany completes first construction phase
With the installation of conductor pipes, the planned geothermal heating project of SWM in Michaelibad, Germany has completed tits initial construction phase.
The first phase of the construction work for the planned geothermal heating project on the grounds of the Michaelibad swimming pool in Munich, Germany has been completed. The year 2025 was dedicated to this phase, following the groundbreaking in late 2024. The project will now proceed to the construction of the drilling site and cellars, with the start of heat supply targeted by 2033.
The Michaelibad project will be the seventh geothermal plant in Munich of local utility Stadtwerke München (SWM). From 2033 onwards, the new facility will supply geothermal heat to around 75,000 Munich residents. The project is also part of the long-term goal of the utility to cover all the district heating needs of Munich with environmentally friendly heat by 2040.
The Michaelibad geothermal plant is planned to have a heating capacity of 80 MWth, which will then be supplemented by a large heat pump with a capacity of 21 MWth. The project was first announced in 2022, with SWM indicating that Michaelibad is located right at the heart of their supply area, thus providing an opportunity to generate the heat where it is needed.
The initial construction phase involved the construction of a perimeter noise and visual barrier, a domestic water well, and a visitor center. This culminated in the installation of the conductor casing for the eight planned boreholes (four production and four reinjection). According to SWM, the construction of the drilling cellars is expected to start by the middle of 2026. This will then be followed with deep drilling, the construction of the heating station, and the construction of the district heating pipeline.
