Middenmeer, The Netherlands

Four deep geothermal wells have been completed in 2014 for two geothermal doublets, commissioned by ECW. The depth of the top of the reservoir rock (sandstones from the Slochteren formation / Rotliegend) is 2 200 m, where the temperatures reach 90 °C. The produced fluids will be used by ECW to supply heat to several greenhouses with large surface areas. For this reason, ECW is in the process of developing a heating network to transport and distribute the heat from the geothermal doublets, but also for potential users to inject heat into the net. So ECW aims to create a robust and sustainable energy supply.

One of the injection wells at Middenmeer will be available for stimulation tests in DESTRESS as a contingency site, if the sites at Westland or Klaipeda cannot be used.
