First heat delivery in early March:

ECW geothermal project automated by Hoogendoorn at an advanced stage

The progress of the ECW geothermal project in Wieringermeer, the Netherlands, are at an advanced stage. For this leading project, Hoogendoorn supplies the process automation and partner Van der Laan provides the installation. This is done in close cooperation with VB group, specialized in geothermal, who provides the above-ground geothermal installations. All stakeholders are working hard to complete the final preparation in order to deliver the first heat in March. This enables eight greenhouses, with a total of 300 hectares of cultivation area, to make use of geothermal energy and save at least 15 percent gas.



Final preparations

Out of the two doublets that are being drilled to win geothermal heat, doublets 1 is ready to use. Doublet 2 is at the moment in the last phase of its drilling-operation. Meanwhile, the pipeline route from the rig to the greenhouse owners is ready. At present, welding the substations to the greenhouses is in progress.
This way geothermal energy can be delivered to the local greenhouses. The construction of the cabinet is in full swing and the heat exchangers are now placed.

Special temperature sensors

In order to accurately measure the heat transfer from the heat exchanger, Hoogendoorn has delivered special temperature sensors with a very high accuracy and stability. These sensors are calibrated specifically for this project by a measurement institute and come with a certificate.


First heat delivery

End February, the first part of the control will be taken into operation. This means that the process control of Hoogendoorn can be installed and made ready to use. In early March, the first heat can be delivered.



15 per cent reduction in gas

As this total greenhouse complex will use geothermal energy as a renewable energy source, the pump can continue to run day and night. Hereby, the well provides a high return on investment. In addition, geothermal energy reduces CO2 emissions by 70 percent when being compared to traditional heating. Hereby, at least 15 percent of gas saving for the glass greenhouse companies is calculated.

The Agriport A7 greenhouse area includes several large-scale greenhouses that grow tomatoes and peppers. The first drilling has already shown that at a depth of 2600 meters of water over 90 degrees Celsius can be won. This relatively high temperature is favourable for the heat output.
