Apply for a loan with repayment subsidy for highly efficient plants or aggregates


The Federal Ministry for Economic Affairs and Energy (BMWi) promotes measures to increase energy efficiency in companies.
You can receive funding for the following measures:

  • electric motors and drives,
  • Pumps for industrial and commercial applications
  • Ventilators
  • Compressed air systems and their higher-level control
  • Plants for waste heat utilization or heat recovery from wastewater,
  • Insulation of industrial plants or plant components,
  • Frequency.

You will not receive any funding:

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

If you want to buy systems or units for energy efficiency, then you can get a loan of up to EUR 25 million.
The amount of the grant in the repayment of the loan depends on the size of your company:

  • small and medium-sized enterprises (up to 249 employees and annual turnover maximum EUR 50 million or balance sheet total maximum EUR 43 million): 40 percent of the eligible costs,
  • large companies (250 or more employees and annual turnover more than EUR 50 million or balance sheet total higher than EUR 43 million): 30 percent of the eligible costs.

Eligible costs are:

  • all costs of implementing the measure,
  • Additional costs for planning and installation.

With this funding, the eligible ancillary costs are limited to a maximum of 30 percent of the investment costs.
You can receive a maximum repayment subsidy of EUR 200,000.
You will only receive the repayment subsidy when 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 performance.

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

Reference to further funding opportunities 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 the Economy" (apply for a subsidy for highly efficient systems or aggregates).


You must submit your 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. Financing partners can be a bank, building society or a 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 KfW's website.
  • In the consultation appointment, your financing partner checks whether your planned measure meets all the requirements and whether you are creditworthy.
  • You fill out the loan application together with your financing partner. Your financing partner will inform you which further forms and documents you need for your application.
  • Your financing partner submits the completed loan application to KfW. KfW will examine your application and decide on the funding.
  • You will then be informed by your financing partner whether your loan with repayment subsidy will be approved.
  • Conclude the loan agreement with your financing partner and start with 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
    • that you have spent the money from the loan on the measure and
    • a confirmation from the manufacturer or supplier that your measure technically fulfils the service (specialist entrepreneur's declaration).
  • You submit these proofs 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 subsidy as a credit note.

It is best to seek advice from an energy efficiency expert before applying for funding. Small and medium-sized enterprises (SMEs) can apply for grants for advice from the Federal Office of Economics and Export Control (BAFA) in the "Federal Promotion of Energy Consulting in SMEs" programme.

When applying, you must submit:

  • Product data sheet, material data sheet or manufacturer's certificate of the system or unit to prove the high efficiency. If the efficiency does not result from this, you must submit a manufacturer's declaration:
    • for WRG compressors: Proof of eligibility for funding - Manufacturer's declaration WRG Kompressoren
    • for compressors: proof of eligibility - manufacturer's declaration compressors
    • for fans: proof of eligibility for funding - manufacturer's declaration for fans
