Geothermal energy supply solutions from a single source

Our business covers the full range of geoscientific and engineering solutions to geothermal energy problems. The projects can be supervised from geological exploration, through the planning of wells and the surface thermal water loop, to heat and power plants and consumer systems. The know-how acquired since 1991 has been consistently expanded and developed since then.


We can refer to completed reference projects for almost all technologies developed by GTN in Germany, Europe and Latin America. The experience feedback from their construction and operation guarantees you the implementation of your projects at any time in accordance with the latest state of the art.
