Grupa Oczyszczalnia Ścieków is to modernise its combined heat and power (CHP) plant at Łódź in a project which will make the sewage treatment facility the second largest producer of renewable energy in the Lodz region. According to a report on GRAMwZIEILONE.pl on 6th March 2018, the project will involve the installation of two new 1.2 MW turbines which will produce electricity and heat from the biogas produced from sewage sludge.
Upon completion, the plant will produce up to 70% of Grupa Oczyszczalnia Ścieków's electricity requirements and 100% of its heat requirements. Electricity production by the Łódź treatment plant in 2016 amounted to 10,064 GWh. This will increase to approximately 19 GWh.
The project, including renovation and construction works and the modernisation of measuring systems, will cost approximately PZL 6.2 million.
