  • Subsidies available
  • Innovative solutions

To make this measure more effective and tailored to the specific context of your company, we recommend that you first perform an overall analysis of your energy situation.

Replacement of individual refrigeration units with a single unit fitted with a variable speed compressor.

In a butcher shop, the refrigeration cycle ensures the cold rooms are cooled. These refrigeration units, which are subject to operating variations, are often separate and not or very little regulated.

The project consists in replacing small production units supplying cold rooms with a main, centralised cold production unit, controlled with a frequency variation on the refrigeration compressor motor.

By installing this technology, which has been available on the market for more than 5 years, the company may save between 15 and 20% on its energy bills. Although this measure has a fast return on investment, implementing it is complex and requires a temporary production shutdown.

In an installation with individual refrigeration units, the air evaporator is influenced by the climate of the room it cools. The system is disrupted every time a door is opened or food is loaded.  In addition, the operation of the condenser is also affected by external temperature variations.

Energy and environmental impact

The new centralised refrigeration unit will result in energy savings on two levels:

  • improved refrigeration efficiency: the energy efficiency ratio (EER) is greater on the final installation
  • improved control due to speed variation

State subsidy application

State subsidies

Please note: any application for government or non-government subsidies must comply with the “incentive effect”, subject to compliance with the subsidy conditions.
To ensure that the ‘incentive effect’ is respected, no binding commitment (signing a quotation; paying an advance) may be made BEFORE submitting the application file or receiving the agreement in principle from the State or the electricity and natural gas supplier following an application for subsidies.

SME Packages – Sustainability

  • Financial Aid for small and medium-sized enterprises covering up to 70% of eligible costs for the implementation of a project aimed at reducing the environmental impact. The eligible project budget must be in a range from 3.000 € to 25.000 € excl. VAT.
  • For more information:

Environmental protection scheme – Investment aid for the protection of the environment

N.B. State subsidies cannot be combined for the same project

Subsidies from electricity and natural gas suppliers

Since 2015, natural gas and electricity suppliers are required to make energy savings for consumers under the obligation scheme. Since then, energy suppliers have been offering support and advice, as well as subsidy programmes for consumers to implement energy efficiency measures.

The following suppliers offer this service for companies:

N.B. Supplier subsidies can be combined with any state subsidies for the same project.

Tax relief for investment in an ecological and energy transition project

The tax relief is calculated based on the investments and operating expenses incurred as part of an ecological and energy transition project.
The tax relief rate is set at 18% and is applied directly to the amount of tax due.
This deduction can be combined with standard state subsidies.

For the project to be eligible, it must meet at least one of the following objectives:

  • Improve the energy efficiency of a production process
  • Improve the material efficiency of a production process
  • Decarbonise a production process
  • Reduce air pollution at the production site (excluding CO2 emissions)
  • Produce or store renewable energy for self-consumption
  • Promote the extended use of products through reuse

For certain objectives, minimum thresholds must be met.
To verify your eligibility and ensure that these thresholds are satisfied, it is recommended that the impact of the measure on one of the above conditions be certified by an expert or a design office.

For questions: Ministry of Economy – Bonus

This type of project may be eligible, provided that the implemented project relates to the company’s main economic activity, the eligibility thresholds are met, and that all other criteria set out in Article 152bis L.I.R. are complied with.
