Třinecké Železárny is investing over $180 million in a combined cycle power station

The new 62 MW power unit will form part of the plant’s decarbonisation programme and is due to come on stream in 2030

The Czech steelworks Třinecké Železárny has signed a contract for the construction of a new combined cycle power station worth over 4 billion Czech koruna (around $185 million). The project is being carried out by a consortium comprising ČEZ ESL and INVELT servis, with the facility scheduled to come on stream in the second half of 2030. This is stated in a press release.

The new 62 MW power complex will be one of the key elements of a large-scale decarbonisation and modernisation programme at the Czech Republic’s largest steelworks. It will replace the K11 coal-fired boiler at the E3 combined heat and power plant, thereby reducing CO₂ emissions and cutting the cost of purchasing emissions allowances.

The project involves the use of a combined-cycle gas turbine capable of co-firing hydrogen, as well as a heat recovery boiler for the production of high-pressure steam, electricity and heat. By utilising waste heat, the plant will be able to provide district heating not only to the town of Třinec and surrounding settlements, but also to neighbouring Český Těšín. The plant currently supplies heat to around 9,000 households, hospitals and schools.

Roman Hajde, Chief Executive of Třinecké železárny, noted that the investment reaffirms the company’s long-term strategy of more environmentally friendly steel production and a gradual transition to new energy sources. For its part, the management of Energetika Třinec emphasised that the new facility will diversify the company’s fuel base, increase its energy independence and help it respond more effectively to fluctuations in fuel prices.

Preparatory work has already begun and includes design work and the signing of contracts with key equipment suppliers. Hundreds of specialists will be involved in the project, and the complex will comprise not only a turbine and a boiler but also new control systems and separate process facilities.

It is worth noting that in 2025, the Czech Republic produced 2.43 million tonnes of steel, matching the 2024 level. This indicates that the country’s figures continue to remain at historically low levels. Steel consumption in the country stood at 5.5 million tonnes at the end of 2025, yet this result is still the second-worst since the 2009 financial crisis.
