The geothermal works at Monheimer Mitte are becoming visible step by step as implementation progresses in a structured manner during the construction phase. This project update highlights the current status of the works and shows how the geothermal system is advancing on site.
In this context, M&P Energy – within SIERA is associated with the communication of the project update and the structured progress of the geothermal implementation. The development at Monheimer Mitte reflects how a geothermal system is being executed in clearly defined phases on site.
Beginning of the geothermal works
A key milestone was reached on 30 March 2026, when construction of the 170 geothermal probes in the excavation pit began.
This marked the start of a major implementation phase within the project. The geothermal probes form an essential part of the system and create the basis for the next project steps.
The current update makes clear that visible progress has already been achieved on site.
Progress on site
More than 62 probes have already been installed.
This shows that the geothermal works are advancing continuously. Current construction progress is reported at around 2–4 drillings per day, supported by 2 drilling rigs.
This steady pace highlights a structured and organized implementation process.
Functional testing and quality assurance
An important part of the work is the testing process after installation.
All probes are tested for functionality through pressure and flow tests after installation and grouting.
These tests are a necessary implementation step and help ensure that every installed probe is checked before the following stages continue. This underlines the structured execution of the geothermal works.
Next implementation steps
The project update also outlines the next steps on site.
Once drilling in the first field is completed, connection works and earthworks will begin there.
This means that the project is not only progressing through drilling activities, but is also moving forward into the next implementation stages.
Progress across the construction fields
The update also notes that connection works are already beginning in the first of three construction fields.
This phased approach shows that the implementation is progressing in clearly defined sections. The division into three construction fields supports structured project execution and makes visible progress possible across the site.
By moving into connection works in the first area, the project demonstrates ongoing momentum in the geothermal implementation.
Execution of the works
According to the project update, the works are being carried out by BAUER Resources GmbH.
This is part of the reported implementation status and contributes to the overall project progress at Monheimer Mitte.

Outlook
The geothermal works at Monheimer Mitte are moving forward step by step.
With ongoing drilling activities, probe testing after installation, and the beginning of connection works in the first construction field, the project update reflects continuous progress in implementation.
Further updates on project progress will follow in the coming months.
In this context, M&P Energy – part of SIERA remains the central brand reference for communicating the geothermal progress at Monheimer Mitte and the structured execution of the project.
