Stimulering Duurzame Energieproductie en Klimaattransitie (SDE++)
The main Dutch operating subsidy for large renewable energy and CO2 reduction projects.
SDE++ supports projects where the sustainable or CO2-reducing option is still more expensive than the market alternative. For COMCAM clients, SDE++ is often relevant for larger solar, heat, renewable gas, low-carbon heat or low-carbon production projects. RVO has announced the 2026 round for 27 October to 26 November 2026.
2026 round
27 October to 26 November 2026 (RVO, page checked 31 August 2026)
2026 budget
EUR 8 billion
Application method
Five phases; earlier phases require lower subsidy intensity
Status
Temporarily closed for applications; opens 27 October 2026
Reference date: Checked 2 September 2026 against RVO; RVO page content dated 31 August 2026. Always verify the current rules, budget status and deadlines with RVO before submitting an application or making investment commitments.
Where the opportunity is
- Large-scale renewable electricity projects.
- Renewable heat, renewable gas and low-carbon heat.
- Low-carbon production and CO2-reduction technologies.
- Projects where permitting and business case preparation can start before the round opens.
Key conditions to check
- Required permits usually need to be available at the moment of application.
- Do not make irreversible investment commitments before the application rules allow it.
- The project must fit one of the eligible categories and technical requirements.
- The subsidy request must match the correct phase and base amount.
Do not let the subsidy choose the technology.
COMCAM can connect SDE++ to the energy portfolio: production profile, offtake, PPA structure, grid capacity, imbalance exposure and the interaction with procurement strategy.
Common pitfalls
- Treating SDE++ as a standalone subsidy instead of part of the energy strategy.
- Underestimating permit lead times and grid capacity constraints.
- Applying in the wrong phase or with incomplete financial assumptions.
Practical next steps
- Check category fit and technical requirements.
- Verify permit, grid and offtake readiness.
- Model the project against market prices and portfolio needs.
- Prepare application documentation well before 27 October 2026.
