In the Overbuurtse Polder in Bergschenhoek, at Warmoeziersweg 56, one of our deep geothermal energy systems is located. Here, we extract renewable energy from deep-earth heat.

Together with AgroEnergy, we supply heat to several greenhouse horticulture companies in the region. The system has been operational since 2018 and plays a central role in the local cluster’s sustainability.

The geothermal source is about 2,000 meters deep and extracts formation water at approximately 60 °C from sandstone layers. Heat is transferred through a district heating network to connected greenhouses.

After heat extraction, the cooled formation water is reinjected into the subsurface in a closed-loop, where it's reheated. This creates a sustainable system delivering over 100,000 MWh of heat annually.
