As part of the Green Energy Park project in Gliwice, Poland
Valmet is set to supply the complete Valmet DNAe Distributed Control System (DCS) and safety systems for PEC Gliwice Sp. z o.o’s waste-to-energy steam unit, part of the Green Energy Park project in Gliwice, Poland
The order was placed by the Engineering, Procurement, and Construction (EPC) consortium consisting of Mostostal Zabrze Gliwickie Przedsiębiorstwo Budownictwa Przemysłowego S.A., Oschatz Power, and Przedsiębiorstwo Remontów Ulic i Mostów S.A. (PRUiM).
The automation system has been developed to ensure safe and efficient operation of the complex multifuel energy facility. It also hopes to maximise energy recovery, enable transparent monitoring and data-driven optimisation, and help reduce operating costs and environmental impacts.
Krzysztof Szaliński, president of the Management Board, PEC Gliwice Sp. z o.o., said, “Our Green Energy Park is a key investment within the long-term strategy to modernise the city’s heating and waste processing infrastructure. It is a flagship circular-economy project for the city, and it was essential for us to equip it with modern, reliable technologies ensuring safe and highly efficient operation. We needed a comprehensive automation and safety concept capable of integrating all process areas and supporting the long-term stability of the facility. Advanced automation will play a key role in enabling efficient, safe and reliable operation of this multifuel energy system.”
Dr Christian Linder, managing director, Oschatz Power, said, “The facility is being constructed by a consortium responsible for the overall EPC scope, combining construction expertise with advanced process engineering capabilities. In preparing the automation concept for this project, we focused on solutions offering high integration capability, a SIL3-compliant safety architecture, and user-friendly operation supported by advanced analytics. From our previous cooperation with Valmet, we know their technology stands out for its strong track record in waste-to-energy and district-heating applications, as well as its extensive know-how in the energy sector.”
Grzegorz Łach, sales manager, Automation Solutions business area, Valmet, said, “We are proud to support PEC Gliwice in building a modern, sustainable heat and power facility for the city. This project is an excellent example of how advanced automation contributes to the efficient, safe, and reliable operation of multifuel energy systems. Our state-of-the-art Valmet DNAe DCS, combined with close international-local cooperation, showcases Valmet’s ability to deliver both deep technical competence and responsive support throughout the entire project lifecycle.”
Green Energy Park in Gliwice is one of Poland’s most modern circular-economy energy projects. It expands the existing heating plant with a high-efficiency steam block and includes a new 25MWt/4MWe unit with a grate-fired boiler, a backpressure steam turbine, and a 10MWt heat pump for heat recovery from moist exhaust gases. The unit converts non-recyclable municipal waste, including pre-RDF shredded bulky waste and dried sewage sludge, into energy, producing over 136,000MWh of heat and 22,000MWh of electricity annually. As a result, the city will reduce coal consumption by 25,000 tonnes and decrease CO2 emissions by over 43,000 tonnes annually.
The delivery includes Valmet DNAe DCS for monitoring and controlling the waste-to-energy plant, integrating all process units from fuel feeding to flue gas treatment. It also features a Safety Instrumented System (SIS) for burner and boiler protection, with safety interlocks up to SIL 3.
The system also provides advanced capabilities for alarming, trending, and long-term data archiving, ensuring high availability through advanced diagnostics and safety functions. The scope also includes the integration of auxiliary systems supplied by consortium partners, as well as commissioning support and operator training.
Valmet provides comprehensive, plant-wide automation solutions for waste-to-energy facilities, enhancing waste incineration performance and overall operational efficiency through integration and advanced control technologies.
