A new HRSG for a combined cycle power plant in Poland will contribute to save 1.2 million tons of CO2 per year

August 22nd 2022

The John Cockerill HRSG technology has been chosen by MYTILINEOS and Siemens Energy through a successful e-bidding for the design and supply of a Benson-type boiler. This new John Cockerill boiler will be installed behind a Siemens Energy SGT5-4000F gas turbine in the future combined cycle power plant of Grudziadz (Poland). The new equipment will contribute to save 1.2 million tons of CO2 per year.

John Cockerill has already designed and supplied such steam generators under a Siemens Energy license for power stations in the Netherlands and the UK. The construction of this new 560 MW gas-steam power station is in open consortium with MYTILINEOS and Siemens Energy and will definitely accelerate the Polish energy transition, moving away from coal. This is therefore an important step towards Poland’s decarbonation as the Grudziadz combined cycle power plant will significantly help reduce CO2 emissions in the country and is intended to replace expiring production from coal-fired power plants, saving approximately 1.2 million tons of CO2 emissions per year.

This power station will produce up to 50% more electricity thanks to the heat recovery steam generator (HRSG), which will transform the waste heat from the gas turbine into steam, which will then be used in a Siemens Energy SST-5000 steam turbine, generating extra power.
