In 2025, we contributed to accelerating the modernisation of Slovakia’s energy infrastructure. Our investments, worth a total of €18 million, were directed towards the construction of renewable energy sources, modern cogeneration units, photovoltaics and battery storage facilities – with the aim of reducing CO₂ emissions, fossil fuel consumption and increasing energy security for cities and industry.
OUR INVESTMENT 2025:
- € 2.5 million – modernisation of thermal management
- € 15.5 million – energy development projects
Modernization of centralized heat supply in Senica
In Senica we are carrying out an extensive modernisation of the centralised heat supply system. The project includes the reconstruction of primary and secondary distribution systems, modernisation of heat transfer stations and increasing the efficiency of the entire system.
- Total investment: € 7.4 million (2025 – 2026)
- New primary pipelines: 1 679 m
- Rehabilitation of secondary distribution lines: 3 699 m
- Emission savings: 1 600 tonnes CO₂ per year
The modernisation will bring more comfort for the residents, a more stable system with a longer service life, fewer breakdowns and better regulation of the heat supply.
Biomass boiler house and thermal infrastructure for Stellantis Slovakia
In Trnava we are building one of the most important decarbonisation projects in the industry in Slovakia. A new biomass boiler house and a complex thermal infrastructure will supply energy to the key technological operations of the Stellantis Slovakia plant.
- Biomass boiler plant output: 9 MW
- Length of pipelines: 3.9 km
- Natural gas savings: ~50 %
- Emission reductions: ~10 000 tonnes CO₂ per year
The project is a model example of the use of renewable sources in an energy-intensive industrial operation. It is the first of a series of investments planned to support the energy transformation of Slovak industry towards lower emissions, higher efficiency and long-term competitiveness.
Cogeneration and biomass source in Pezinok
In Pezinok, we are preparing the construction of a new combination of renewable source and cogeneration, which will ensure efficient production of heat and electricity for the entire locality.
- Biomass boiler: 299 kW
- Cogeneration: 200 kWe / 304 kWt
- Emission savings: ~305 tonnes CO₂ per year
The aim of the project is to increase energy self-sufficiency and reduce long-term energy costs.
Photovoltaic power plants in Veľké Kapušany
We have installed two photovoltaic power plants on the roofs of the boiler houses in Veľké Kapušany, which will produce their own renewable electricity directly for the needs of the plants.
- Power: 55 kW + 60 kW
- Own electricity production
- Higher energy self-sufficiency
- Emission reductions: ~27 tonnes CO₂ per year
Modernisation of cogeneration in Malacky
In Malacky, we completed the replacement of the cogeneration units in the biomass boiler house, which significantly increased the efficiency of energy production.
- Electrical power: 616 kWe
- Thermal output: 730 kWt
The modernisation will enable more efficient use of the electricity generated and greater stability of energy supply.
Building a sustainable energy future
“We are systematically investing in modernising the energy sector to deliver real savings, greater security of supply and measurable emissions reductions. We are harnessing renewables, increasing energy efficiency and replacing fossil fuels where it makes the most sense – in cities and in industry,” says Ing. Miroslav Pajchl, Director of Heat Production and Distribution of ENGIE Group
Our completed as well as in-progress projects prove that modern energy can be reliable, efficient and environmentally friendly at the same time. By investing in the technologies of the future, we are actively contributing to the transition to low-carbon and sustainable energy.
