SBB ENERGY S.A. has successfully completed the modernization of the OOG 320 K3 boiler for ORLEN S.A. at the Płock Combined Heat and Power Plant.

The modernization was carried out under a contract valued at over PLN 100 million, executed in the years 2024–2025.

The project involved the comprehensive adaptation of the boiler to operate on heavy fuel oil (HFO) as the primary fuel, with the option to alternatively fire a mixture of this fuel and gas. The objective of the project was to ensure compliance with the Regulation of the Minister of Climate and Environment of 24 September 2020 on emission standards (Journal of Laws 2020, item 1860), as well as Directive 2010/75/EU of the European Parliament and of the Council (the Industrial Emissions Directive-IED).

As part of the investment, SBB ENERGY S.A. implemented state-of-the-art environmental protection technologies, including Selective Catalytic Reduction (SCR) for flue gas denitrification and a dry electrostatic precipitator (ESP) for dust removal. The pressure part of the boiler was also rebuilt, significantly improving its efficiency and operational safety.

Upon completion of all modernization works, the Regulatory Run and the 72-hour Performance Test Run were carried out with positive results, confirming the proper functioning of the installation.

The final acceptance protocol was signed on 15 October 2025, formally concluding the project.

“We are pleased to confirm the successful completion of all modernization stages. The project for ORLEN S.A. is another example of our effective delivery of technologically advanced undertakings that contribute to reducing emissions and improving the energy efficiency of Polish industry,” said Ziemowit Słomczyński, President of the Management Board of SBB ENERGY S.A. The successfully completed project reaffirms SBB ENERGY S.A.’s position as one of Poland’s leading contractors for industrial installation modernization, delivering investments in line with the highest technical and environmental standards.
