Apply for a loan with a repayment subsidy for high-efficiency systems 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 use
  • fans,
  • Compressed air systems and their higher-level control
  • Systems for waste heat utilisation or heat recovery from waste water,
  • Insulation of industrial plants and plant components,
  • frequency converters.

You will not receive any subsidies:

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

If you want to buy energy efficiency equipment or units, 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): 40 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): 30 percent of eligible costs.

Eligible costs are:

  • all costs for the implementation of the measure,
  • ancillary 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 of EUR 200,000 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 are not entitled to the grant.

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 grant for high-efficiency systems or aggregates).

Applications may be submitted by

  • domestic and foreign commercial enterprises that are majority privately owned
  • municipal enterprises
  • freelance professionals
  • contractors who implement energy efficiency measures

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 3 years
  • Your measure must meet minimum technical requirements
  • Your measure must cost at least EUR 2,000 net, including incidental costs

When submitting your application, you must submit:

  • Product data sheet, material data sheet or manufacturer's certificate of the system or unit in order to prove the high efficiency. If the efficiency is not evident from this, you must submit a manufacturer's declaration:
    • for WRG compressors: Proof of eligibility - Manufacturer's Declaration WRG Compressors
    • for compressors: Proof of eligibility - Manufacturer's declaration for compressors
    • for fans: Proof of eligibility - Manufacturer's declaration for fans

  • for contracting projects: Confirmation of contracting project

  • for SME funding: Self-declaration of compliance with the SME definition

  • for "de minimis" funding: "de minimis" declaration

  • for AGVO funding: reference offer for measure

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

  • Confirmation after implementation of the investment measure


  • Specialist contractor declaration on the installed technologies - in module 1 (except insulation)


  • Specialist company declaration on the installed technologies - in module 1 (for insulation measures)
  • Application:
    • until 31.12.2022
    • before the start of the measure

  • Call deadline of the loan: within 12 months after 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, your 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
    • a confirmation from the manufacturer or supplier that your measure technically meets the performance (specialist contractor declaration).
  • 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 the advice from the Federal Office of Economics and Export Control (BAFA) in the programme "Federal funding for energy advice in SMEs".
