Daldrup & Söhne AG receives order to sink a geothermal well for geothermal power plant in Switzerland

Oberhaching / Ascheberg, 23 June 2021 - Drilling technology and geothermal specialist Daldrup & Söhne AG (ISIN DE0007830572) has been awarded a contract by a regional Swiss consortium to drill a well to develop a geothermal aquifer in the Rhone Valley. Drilling with the Drillmec "DS 20" rig with a hook load of 272 tonnes is scheduled to start in October 2021. The contract is worth a mid-single-digit million euro amount.

The well is expected to be drilled to a depth of approximately 3,000 metres. The thermal water will be used to generate electricity and heat. To this end, a consortium plans to build a geothermal power plant using ORC technology (Organic Rankine Cycle) with an electrical output of at least 4.2 GWh and a thermal output of about 15.5 GWh. Part of the heat is also to be made available to a traditional thermal spa and health resort.
