Conditions SDE++


Do you want to apply for a Stimulation of Sustainable Energy Production and Climate Transition (SDE++) subsidy? The following conditions apply to all SDE++ categories.


Only for the intended producer

The SDE++ subsidy is intended for companies and organisations (non-profit and otherwise) that produce sustainable energy or apply CO2-reducing techniques. Only the intended producer may apply for the SDE++ subsidy. You are an intended producer if you intend to set up and operate the production facility yourself. If you are building and operating parts of a production facility with other parties, you should apply as a partnership. National government entities cannot apply for a subsidy.

One application per category

For each application round of the SDE++ scheme you may submit a maximum of one application per category of production facility, and per address at which your production facility is located. However, you may apply for a subsidy for different categories of production facilities at the same address.

Application rate

The subsidy rate applied for (the ‘submission rate’) may vary. You should submit your subsidy application with up to four decimal places per unit of product (per kilowatt hour or tonne of CO2). This allows you to tailor your subsidy application more closely to your project. The submission rate may not exceed the maximum rate for the relevant phase. It may also not exceed the maximum base rate for the technology concerned.

Feasibility study

You are required to submit a feasibility study with your application. The feasibility study should include:

  • A description of your project;
  • An energy or yield calculation;
  • An operation calculation;
  • A financing plan; and
  • Various supporting documents.

Different supporting documents are required for the ‘Solar PV ≥ 15 kWp and ≤ 1 MWp’ category. To find out more about the elements the feasibility study must contain, visit the page Haalbaarheidsstudie SDE++ (information in Dutch).


In most cases, one or more permits are required for the production facility. For almost all categories, the competent authority must have issued these permits before you submit your subsidy application. Please send the permits with your application. The permits that apply are different for each category.

Owner consent

If you are not the owner of the intended location for the production facility, you need the consent of the owner of the location to build and operate the facility. Use the ‘Site owner consent template’ for this purpose. You can find it on the page Bijlagen bij uw aanvraag (information in Dutch).

Transmission capacity indication

If you will be producing electricity, you must submit a transmission capacity indication. This is an indication we use to assess whether there is sufficient transmission capacity available for the location for which you are applying for a subsidy. Ask your grid operator to prepare the transmission capacity indication for you. Because the transmission capacity of the electricity grid can change, the indication must be issued for the application round in which you are applying for a subsidy. See also the page Bijlagen bij uw aanvraag (information in Dutch).

Private grid

Would you like to connect your production plant to a private grid (Closed-Distribution System grid)? In that case, you and the private grid operator must request a transmission capacity indication from your national or regional grid operator who is responsible for the transfer point to which the private grid is connected. If you do not know who your network operator is, you can check at

Grid operators

Other subsidies and over-incentivisation assessment

If you receive an SDE++ subsidy for a production facility, you cannot apply for a Sustainable Energy Investment Subsidy (ISDE), Energy Investment Allowance (EIA) and/or the Subsidy Scheme for Cooperative Energy Generation (SCE) for that installation. An exception to this rule is non-building-mounted solar PV projects for which a subsidy is granted between 2016 and 2021. For these projects, it may be possible to apply for an EIA to cover the investment costs of the grid connection. Check the page Energielijst 2021 (information in Dutch) to see if this applies to your situation.

Have you received any other subsidies besides the SDE++? If so, one year after the facility is commissioned we will check whether your SDE++ subsidy meets the conditions of the European Commission’s Environmental Aid Guidelines (EAG). We will do this using the MSK-toets. If the test shows that you have received or will receive more financial support than is allowed, this will be a case of over-incentivisation. It may lead to a reduction in the SDE++ subsidy paid out. 
For a number of categories, we always check for over-incentivisation. We do this even if you do not receive any other financial support. This applies to the following categories:
  • Electric boilers;
  • Use of waste heat;
  • Electrolytic hydrogen production;
  • CCS (Carbon Capture and Storage);
  • CCU (Carbon Capture and Utilisation).
