The instrument ‘Stimulering Duurzame Energieproductie+’ (SDE+) is the main instrument for promoting renewable energy production in the Netherlands. The project concerns the second and final evaluation of the instrument and aimed to evaluate its effectiveness and efficiency over the 10 years that the SDE+ has been in place, focussing on the last 5 years.
Additionally, the possibilities for incorporating external costs in the subsidy award mechanism have been explored. The evaluation was used as input for improving the SDE+ successor, the SDE++.

Some of the main analyses in the evaluation were:
-Providing an overview of renewable energy production supported by the SDE+ in the Netherlands.
-Impact of project cancellation in all stages of the project developing process (realisation, production).
-Analysis of additionality of the SDE+, by analysing if the IRR of projects are sufficient without the SDE+.
-Analysis of possible surplus profits and incentives within the design of the SDE+ to limit such surplus profits.
-Overview of administrative costs of implementation of the subsidy scheme.

Some of the main analyses in the evaluation were:

  • Providing an overview of renewable energy production supported by the SDE+ in the Netherlands.
  • Impact of project cancellation in all stages of the project developing process (realisation, production).
  • Analysis of additionality of the SDE+, by analysing if the IRR of projects are sufficient without the SDE+.
  • Analysis of possible surplus profits and incentives within the design of the SDE+ to limit such surplus profits.
  • Overview of administrative costs of implementation of the subsidy scheme.
