Between 2006 and 2008 Fiddlers Ferry was fitted with Flue Gas Desulphurisation (FGD) plant to reduce the emissions of sulphur by 94%, meeting the European Large Combustion Plant Directive. In 2010, the station was being considered for the installation of selective catalytic reduction (SCR) equipment. This would reduce the station's emissions of nitrogen oxides, to meet the requirements of the Industrial Emissions (Integrated Pollution Prevention and Control) Directive. The SCR technology would replace the Separated Over Fire Air (SOFA) technology which was used in the station. The SCR equipment was not fitted due to uncertainty over the future of the plant.
