The new project will bring 50% natural gas savings, significant emission reductions and is a model for the decarbonisation of industry in Slovakia
ENGIE Services starts construction of a biomass boiler house and thermal infrastructure for the Stellantis Slovakia automotive plant in Trnava. It is one of the largest investments of this type in Slovakia. The new renewable source will cover 50% of the plant’s heat consumption, generate 36 GWh of biomass energy per year and reduce emissions by almost 10 thousand tonnes of CO₂ per year.
The €17.5 million project is funded entirely by ENGIE Services, which has committed to build and operate the entire biomass-based energy infrastructure over the next 15 years.
“Decarbonisation of industry today is not only an ecological but also an economic necessity. ENGIE, as a long-term and stable partner, offers manufacturing plants comprehensive energy solutions. The project for Stellantis is a prime example of how we can help industry to meet its climate goals and at the same time increase energy independence,” says Juraj Sochor, Director of the Project Implementation and Services Division of ENGIE Services.
Biomass boiler house: the heart of the new energy plant
The new heat source will consist of a 9 MW biomass boiler house using wood chips as the primary energy source.
Key technologies:
- 3.9 km of new pipeline network in the plant area,
- connection to 26 technological devices of the paint shop and assembly.
- storage tanks with a capacity of 500 m³,
- electrostatic filtration and emission minimisation equipment.
The fuel will be exclusively sustainably sourced wood chips, and the project envisages minimal operation of existing gas boilers to cover peak heat demand.
Construction is divided into two phases:
- December 2025 – completion of the construction of the new thermal infrastructure,
- March 2026 – completion of construction of the biomass boiler house and start of operation.
Sustainable production thanks to green solutions
Stellantis Slovakia plans to cover more than half of its energy consumption from its own green renewable sources as early as 2025. The new biomass-fired heating plant will provide approximately 33% of the annual heat production for the entire plant.
“Other upcoming decarbonisation projects include the construction of a photovoltaic power plant and a battery storage facility. Through photovoltaics we would like to cover almost 30% of our annual electricity consumption. The battery storage facility will be one of the largest in Slovakia in terms of capacity,” says Michal Nič, Communications Manager at Stellantis Slovakia.
These measures and projects are a concrete step towards achieving carbon neutrality and also fulfill the brand’s commitment to We Care For The Future.
The road to energy independence in industry
Based on the successful model implemented for Stellantis Slovakia, ENGIE Services offers the same type of cooperation to other industrial plants. Within the framework of “Design & Build”, it can provide the design, construction, financing and also the long-term operation of renewable energy sources.
“Decarbonisation of the industry is one of the strategic areas of focus for ENGIE Services. We bring added value to our customers in the form of extensive experience, technical expertise and a comprehensive portfolio of services, including the energy mix (production and supply of heat, cold and electricity from renewable sources). In addition, by being able to finance and operate the projects independently over the long term, we significantly reduce the investment burden on the plants and enable them to move faster towards decarbonisation,” concludes Juraj Sochor.
The project in Trnava is the first in a series of investments ENGIE Services is preparing to support the energy transformation of Slovak industry towards lower emissions, higher efficiency and long-term competitiveness. Thanks to modern green solutions, industrial plants can reduce their dependence on fossil fuels, increase their own energy independence and prepare for a sustainable future.
