Geothermal project Trias Westland

On May 10th 2017, the unique and innovative geothermal project Trias Westland was launched. For the first time in the Netherlands, the Triassic earth layer will be drilled, this layer lies at a depth of 4 km.Previous geothermal projects in the Netherlands have drilled up to 2,5 km into the so called Lower Cretaceous layer.

After the necessary preparations Trias Westland drilled a trial well to investigate if sufficient warm water is present at 4 km depth at the aimed temperature of 140 ºC to incorporate all of the participating companies into the heat network. Research has shown that the Trias sands at a depth of 4 kilometers at this location are not suitable for cost-effective heat extraction. The project now focuses on the Onder Krijtlaag at 2.7 kilometers depth. The geothermal source was put into operation in July 2019 and 26 of the 49 participating companies were connected.

The participants work together through an own cooperation and with large regional parties. The project significantly contributes to the sustainable and economic goals of Greenport Westland and is supported by Westland Agenda II.

AAB is, among others, responsible for the installation and exploitation of the geothermal well. This consists of, amongst others, civil-technical facilities (soil, piping, piling, concrete, asphalt etc.), utilities (water, electrics internet) and building facilities (pump station).
