Competence and capacities in deep geothermal energy: DMT GROUP sets up as general contractor

The DMT GROUP, Essen/Germany, a globally active company for engineering services and consulting of the TÜV NORD GROUP, is repositioning itself along the entire value chain and, as a general contractor for deep geothermal energy, accompanies customers from the idea to the finished heating plant and the first kilowatt hour of heat generated.

When planning projects and developing potential sites for deep geothermal heating plants, municipal utilities, energy suppliers and companies are often under considerable time pressure and have to deal with a high degree of complexity on the way to decarbonising their heating networks. DMT provides them with new, comprehensive support models as a general contractor.

DMT’s expertise in the field of deep geothermal energy covers all the process steps required for commissioning a geothermal heating plant: project planning and design with application and approval procedures, public participation, feasibility study, economic feasibility study, risk analysis and funding advice. DMT then takes over the site investigation using 3D seismics as well as the drilling planning, drilling and borehole measurements, data processing and modelling. Finally, the last phase of the project involves the planning and construction of the plant, right up to the connection of the finished heating plant to the grid.

With DMT as general contractor, the effort for customers is minimised. All responsibilities, planning and implementation tasks lie with a single contractual partner, including schedule and budget planning as well as interface management and comprehensive project management. This makes the highly complex path to a geothermal heating plant more manageable for customers and involves considerably less effort on their part − regardless of whether DMT takes over everything completely or parts of the service chain.

DMT has already provided support for a large number of deep geothermal projects, including seismic surveys for GeoHardt GmbH, a subsidiary of MVV and EnBW, one of the largest inner-city 3D seismic surveys ever carried out for Stadtwerke München and the determination of the geothermal potential of the Vienna region for OMV and Wien Energie.

With the increased attention on the part of federal and state politicians for deep geothermal energy in Germany and an improvement in the framework conditions, e. g., in federal funding for efficient heat grids (BEW), DMT is expecting considerably stronger demand for support in project implementation in the coming months and years. This naturally also affects the planning of the capacities that DMT makes available to its customers.

“As soon as the recently submitted BEW funding applications are approved, customers will need advice, site investigation and plant engineering. We have also prepared for this with our capacities. With our setup as a general contractor, we can relieve our customers considerably − and ultimately accelerate the energy and heat turnaround,” explains Maik Tiedemann, Managing Director of DMT.
