As part of the ENGIE Group’s investments in modernizing existing energy sources, we have commissioned new cogeneration units on Stavbárska Street in Bratislava and in Malacky. Both projects are part of the renovation of existing boiler rooms. We are replacing older technologies with new solutions that better meet current requirements for performance, flexibility, and operation.
What are the benefits of installing cogeneration units?
Cogeneration units produce both electricity and heat simultaneously from a single source. Energy that would otherwise go unused in conventional production is utilized directly in our system. The result is greater efficiency without the need for additional inputs.
Generating energy directly at the point of consumption means less dependence on external inputs and more stable operation of the equipment. Operations are more predictable and easier to manage in real time.
Lower operating costs
In addition, cogeneration gives us better control over operating costs. Such solutions are becoming increasingly important, especially in an environment of fluctuating energy prices and growing demands for operational efficiency.
Environmental Benefits of the Solution
More efficient use of fuel means lower energy consumption for the same output, and thus lower emissions. Cogeneration reduces the amount of energy that needs to be generated and supplied from external sources, thereby reducing the overall environmental impact of operations.
The project on Stavbárska Street also includes a photovoltaic power plant (56 kW), which supplements energy production with a renewable energy source directly at the point of consumption.

“Today, sustainable energy must make sense not only from an environmental perspective but also from an operational cost standpoint. Cogeneration is one solution that bridges these two aspects and delivers real value in everyday practice,” concludes Miroslav Mravec, Investment Director of the Energy Division at the ENGIE Group.
