Energy efficiency; application for a loan with repayment subsidy for high-efficiency systems or aggregates.

If you invest in high-efficiency equipment and gensets, you can apply for a loan with a repayment subsidy under certain conditions.


The German 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
  • Systems for waste heat utilization 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 with the measure before submitting the application.

If you want to buy energy efficiency equipment or aggregates, then 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 sales not exceeding EUR 50 million or total assets not exceeding EUR 43 million): 40 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): 30 percent of eligible costs.

Eligible costs are:

  • All costs for implementing the measure,
  • Incidental 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 repayment subsidy.
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 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 program funding options:
You can also apply for a direct grant from the German Federal Office of Economics and Export Control (BAFA) via the "Bundesförderung für Energieeffizienz in der Wirtschaft" funding program (apply for a grant for high-efficiency systems or aggregates).


Applications may be submitted by:

  • domestic and foreign commercial enterprises, the majority of which are privately owned
  • municipal enterprises
  • freelance professionals
  • Contractors who implement energy efficiency measures

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


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 for this purpose.
  • During 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 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
    • 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 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 consulting from the Federal Office of Economics and Export Control (BAFA) in the program "Federal funding for energy consulting in SMEs".
