SDE+ is a ministerial regulation that has as its aim the stimulation of clean, sustainable energy. In 2017, the SDE+ will be open for applications during a period in spring and a period in autumn.  The spring period has ended. During the autumn, the SDE+ is opened for October 3 2017 9:00 hour until October 27 2017 17:00 hour, it has a budget of 6 bilion euro to support projects for sustainable energy. The second round will open in the start of July 2017.

The ministerial regulations for SDE+ 2017 were published on 12 July 2017 ( in Dutch). 

The SDE+ subsidy assists the Dutch government to stimulate the production of sustainable energy. Since 2012 SDE+ has also included the production of sustainable heat. SDE+ is a production subsidy: producers receive a subsidy for the sustainable energy generated.

To be eligible for an SDE+ subsidy you must hold an exploration permit and a permit issued under the Environmental Licensing Act.
More information on the SDE+ regulation can be found on the Netherlands Enterprise Agency website.

Bear in mind that the application for the subsidy must be accompanied by documentation, including:

  • The exploration permit issued under the Mining Act
  • A declaration from the owner of the site proposed for the production installation (only necessary if you are not the owner of the site)
  • A feasibility study

SDE+ geological research
It is mandatory to submit a geological report based on research that meets the stipulations of the SDE+ Geological Research Model. See annex 7 of the consolidated SDE General Implementation Regulation. Further details on the minimum requirements for the geological information accompanying the application for the SDE+ subsidy can be found in the TNO report "Specifications for the geological research for geothermal projects: SDE+ and RNES reporting requirements” (April 2017). Report is in Dutch.

When preparing your application, to calculate the indicative geothermal capacity you may use the DoubletCalc software that can be downloaded from the Tools webpage. This program, which is made available by TNO, makes it easier to create the required graphs of probability values.
