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 recovery or heat recovery from waste water,
  • insulation of industrial plants or plant components,
  • Frequency.

You will not receive any funding:

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

If you want to buy systems or aggregates for energy efficiency, you can get a loan of up to EUR 25 million.
The amount of the subsidy when repaying the loan depends on the size of your business:

  • 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 eligible costs,
  • large enterprises (250 or more employees and annual turnover more than EUR 50 million or balance sheet total higher than EUR 43 million): 30 percent of eligible costs.

Eligible costs are:

  • all costs for the implementation of 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 not receive the repayment subsidy until you have completed your measure. To do this, you must prove:

  • that you 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.

Note on further funding opportunities of the programme:
You can also apply for a direct subsidy 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 partner can be a bank, building society or a financial intermediary.
  • Choose your financing partner and make an appointment for a consultation. If you are looking for a financing partner, you can use the online advice request on the KfW 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 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 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 action, 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 performance (specialist contractor's declaration).
  • You submit this proof 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.

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

Applications can be submitted:

  • domestic and foreign commercial enterprises, the majority of which are privately owned
  • municipal companies
  • freelancers
  • Contractors implementing energy efficiency measures

Further requirements:

  • You must be creditworthy
  • Your company must have its registered office or branch in Germany
  • the funded 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 ancillary costs

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 is not evident, you must submit a manufacturer's declaration:
    • for heat recovery compressors: proof of eligibility - manufacturer's declaration WRG Kompressoren
    • for compressors: proof of eligibility - manufacturer's declaration compressors
    • for fans: proof of eligibility - manufacturer's declaration for fans
  • for contracting projects: confirmation of the contracting project
  • for SME funding: self-declaration on compliance with the SME definition
  • for de minimis funding: de minimis declaration

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

  • Contractor's declaration on the installed technologies - in Module 1 (for insulation measures)
  • Application:

    • before the start of the action
  • Call-off period of the loan: within 12 months after loan approval, in one sum or in partial amounts
  • Proof of use of funds: within 12 months of full disbursement of the loan
