Apply for a loan with a repayment subsidy for measures to provide process heat from renewable energies.


The 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 plants,
  • heat pumps, provided they use renewable heat sources,
  • heat storage systems for these heat generators.

You will not receive any subsidies:

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

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

  • small and medium-sized enterprises (up to 249 employees and annual turnover not exceeding EUR 50 million or balance sheet total not exceeding EUR 43 million): 55 percent of the eligible costs,
  • large enterprises (250 and more employees and annual turnover exceeding EUR 50 million or balance sheet total exceeding EUR 43 million): 45 percent of eligible costs.

Eligible costs are:

  • all costs for the implementation of the measure,
  • ancillary costs for planning and installation.

Eligible costs are also costs for

  • the integration of the measure into the existing process and
  • the 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 only receive the repayment subsidy once 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 fulfils its purpose.

You must keep all invoices and receipts relating to the eligible costs.
Applications for funding are processed by the Kreditanstalt für Wiederaufbau (KfW).
You have no claim to the granting of the subsidy.

Note on further funding possibilities of the programme:
You can also apply for a direct grant from the Federal Office of Economics and Export Control (BAFA) via the funding programme "Federal funding for energy efficiency in industry" (apply for a grant for measures to provide process heat from renewable energies).

Applications can be submitted by

  • domestic and foreign commercial enterprises
  • municipal enterprises
  • farmers
  • freelance professionals
  • 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 subsidised 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

When submitting your application, you must submit:

  • Data collection sheet process heat
  • hydraulic system diagram
  • offer of the planned plant
  • for contracting projects: Confirmation of the contracting project
  • for SME subsidies: Self-declaration of compliance with the SME definition
  • for "de minimis" subsidies: "de minimis" declaration

Which other documents you may need to submit in your case can be found in the annex to the information sheet "Minimum technical requirements for process heat from renewable energies".

Once you have completed your measure, you must submit the following documents:

  • Confirmation after the investment measure has been carried out.
  • Application:
    • until 31.12.2022
    • before the start of the measure
  • Call deadline for the loan: within 12 months of the loan commitment, in one sum or in instalments.
  • Proof of use of funds: within 12 months after full disbursement of the loan

for processing the application: 3 to 6 weeks

Once you have submitted your application, you can begin the action at your own financial risk.

  • Forms: yes
  • Online procedure possible: no
  • Written form required: yes
  • Personal appearance required: yes (at the financing partner)

You will receive the original forms from your financing partner. You fill out the forms together.

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 a consultation. If you are looking for a financing partner, you can use the online consultation request on the KfW website.
  • At 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 will inform you which other forms and documents you need for your application.
  • Your financing partner submits the completed loan application to KfW. KfW will review your application and decide 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.
  • Once you have completed the measure, you must provide proof to your funding partner,
    • that you have spent the money from the loan on the measure and
    • that the measure technically fulfils its purpose.
  • You submit this evidence to your financing partner.
  • Your financing partner checks and confirms your evidence and forwards it to KfW.
  • If KfW has also checked the evidence, you will receive the repayment grant 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 programme "Federal funding for energy consulting in SMEs".
