Efficient hard-coal-fired power plant 

Aberthaw is a coal-fired power plant located in Wales in the UK. With a capacity of around 1,560 MW it can generate enough power to meet the needs of 1.5 million households. We aim to maintain Aberthaw as one of the most efficient coal-fired power stations in the UK.  
We have invested in technologies to reduce emissions at Aberthaw, such as the Flue Gas Desulphurisation (FGD) technology already in operation, that reduces sulphur emissions by up to 95%. More recently we are working towards compliance with the Industrial Emissions Directive (IED) and have installed low NOx boiler technology to Unit 9 reducing emissions by over 90%.  

In early 2016 we announced further investments in NOx emissions improvements to all units. This will enable the station to be compliant with the IED through its ability to use a wider range of coals including high volatile. In addition, we have announced a change to our operating regime, which will focus on ensuring secure capacity is available when needed but with lower energy generation operations. 

As of 31 March 2020 the station will be closed. RWE will transfer Aberthaw Power Station’s existing Capacity Market agreements for the years 2019/2020 and 2020/2021 to third parties and a small proportion to other units within RWE’s fleet. See here for the full press release
