Energy efficiency; application for a loan with repayment subsidy for measures to provide process heat from renewable energies

If you invest in systems for the provision of process heat from renewable energies, you can apply for a loan with a repayment subsidy under certain conditions.


The German Federal Ministry for Economic Affairs and Energy (BMWi) promotes the provision of process heat from renewable energies in companies.
You can receive funding for the following measures:

  • Solar collectors,
  • biomass systems,
  • Heat pumps, provided they use renewable heat sources,
  • heat storage systems for these heat generators.

You will not receive a subsidy

  • for measures required by law,
  • if you have already started the measure before submitting the application.

If you want to buy equipment for the provision of process heat from renewable sources, then you can get a loan of up to EUR 25 million.
The amount of the subsidy in the repayment of the loan depends on the size of your company:

  • small and medium-sized enterprises (up to 249 employees and annual sales not exceeding EUR 50 million or total assets not exceeding EUR 43 million): 55 percent of eligible costs,
  • large companies (250 and more employees and annual sales more than EUR 50 million or total assets higher than EUR 43 million): 45 percent of eligible costs.

Eligible costs are:

  • All costs for implementing the measure,
  • Incidental costs for planning and installation.

Eligible costs are also costs for

  • the integration of the measure into the existing process and
  • yield monitoring and error detection of the installed measurement and data acquisition systems.

You can receive a maximum of EUR 10 million in repayment subsidies.
You will not receive the repayment subsidy until you have completed your measure. To do this, you must prove

  • that you have spent the money from the loan on the measure,
  • that the measure technically fulfills its purpose.

You must keep all invoices and receipts related to the eligible costs.
The applications for the subsidy are processed by the Kreditanstalt für Wiederaufbau (KfW).
You are not entitled to the subsidy.

Note on other subsidy options of the program:
You can also apply for a direct subsidy from the Federal Office of Economics and Export Control (BAFA) via the subsidy program "Bundesförderung für Energieeffizienz in der Wirtschaft" (Federal Subsidy for Energy Efficiency in the Economy) (apply for a subsidy for measures to provide process heat from renewable energies).


Applications can be submitted by:

  • domestic and foreign commercial enterprises
  • municipal enterprises
  • farmers
  • freelancers
  • Contractors who carry out measures for a company eligible to apply.

Further requirements:

  • You must be creditworthy
  • Your company must have its registered office or a branch in Germany
  • the subsidized measure must be implemented in Germany and operated for at least three years
  • more than 50 percent of the process heat generated by the measure must be used for the manufacture of products or services
  • your measure must meet minimum technical requirements


You must submit the application for funding in writing to the Kreditanstalt für Wiederaufbau (KfW).

  • You first need a financing partner, through whom you then submit your application to KfW. A financing partner can be a bank, building society or financial intermediary.
  • Select your financing partner and make an appointment for consultation. If you are looking for a financing partner, you can use the online consultation request on the KfW website for this purpose.
  • During the consultation appointment, the financing partner will check whether your planned measure meets all the requirements and whether you are creditworthy.
  • You complete the loan application together with your financing partner. Your financing partner informs you which other forms and documents you need for your application.
  • Your financing partner submits the completed loan application to KfW. KfW reviews your application and decides on the funding.
  • You will then receive notification from your financing partner as to whether your loan with repayment subsidy will be approved.
  • Conclude the loan agreement with your financing partner and start the measure. KfW will pay you the loan amount in full.
  • When you have completed the measure, you must prove to your financing partner,
    • that you have spent the money from the loan on the measure and
    • that the measure technically fulfills its performance.
  • You submit this evidence to your financing partner.
  • Your financing partner will check and confirm your evidence and forward it to KfW.
  • If KfW has also checked the evidence, you will receive the repayment subsidy as a credit.

It is best to seek advice from an energy efficiency expert before submitting your application for funding. Small and medium-sized enterprises (SMEs) can apply for subsidies for this from the Federal Office of Economics and Export Control (BAFA) in the program "Federal funding for energy consulting in SMEs".


  • Application deadline:
    • until 31.12.2022
    • Before the start of the measure
