It is located at Limpert Bay, near the villages of Gileston and West Aberthaw. The current power station on the site, Aberthaw B Power Station, co-fires biomass and as of 2008 has a generating capacity of 1560 megawatts (MW). The station is the location of a carbon capture trial system to determine whether the technology can be scaled up from lab conditions. The system consumes 1 MW. HistoryThe site of the stations was a golf course before the construction of the first station.[1] Aberthaw "A" Power Station although recorded as first generating power on 7 February 1960, officially opened on 29 October 1963, and at the time it was the most advanced in the world.[2] Aberthaw "B" station opened in 1971. Aberthaw "A" operated until 1995.[3] It was subsequently demolished. Its two {{convert|425|ft}} chimneys were the last section to be demolished, and this was done on Saturday, 25 July 1998.[4] The site now has three generating units, each driven by its own Foster-Wheeler boiler. From 2006-2007 new steam turbines were fitted, allowing each unit to generate an extra 28-30 MW of power. Each unit is now rated at 520 MW. OperationsAberthaw burns approximately 5,000–6,000 tonnes of coal a day. The site usually burns two-thirds Welsh coal with the remainder being either foreign low-sulphur coal or biomass. The station takes its entire coal feed stock in by rail from the Vale of Glamorgan Line, under contract to DBS. Rail facilities included east- and west-facing connections to the main line, three reception sidings, No. 8 and No. 9 merry-go-round loop lines, two gross-weight and tare-weight weighbridges, two hopper wagon discharge hoppers, a former fly ash siding, an oil discharge siding, two sidings adjacent to the former A station, and two exchange sidings.[5][6] Until its closure, the Tower Colliery in Hirwaun supplied much of the coal for Aberthaw. Coal now mainly comes from the Ffos-y-fran Land Reclamation Scheme in Merthyr Tydfil, with other sources including: the Aberpergwm drift and opencast mines in the Neath Valley; and the Cwmgwrach Colliery via the Onllwyn Washery and the Tower Opencast mine based at the site of the original Tower Colliery. Further stocks are sourced from abroad, primarily Russia, and shipped in via the ports of Portbury, Avonmouth and Newport Docks. In response to the UK government's renewable energy obligation that came into effect in April 2002, the station is currently firing a range of biomass materials to replace some of the coal burned. This is due to Welsh coal being less volatile than other coal and as such producing more sulphur dioxide and carbon monoxide. {{Citation needed|date=October 2014}} Flue gas desulphurizationAberthaw B was due for closure, but in June 2005 station owners npower agreed to install new technology to reduce sulphur dioxide emissions by installing Flue Gas Desulphurization (FGD) equipment. This was to reduce sulphur dioxide levels by 90% by 2008, when new European environmental regulations came into place.[7] Construction of the equipment started on 21 June 2006, with a tree-planting ceremony attended by the Welsh Minister for Enterprise, Innovation and Networks, Andrew Davies. The desulphurization FGD project is being carried out by a consortium of ALSTOM and AMEC, which will employ 500 workers on site at the peak of construction.[8] Nuclear proposalIn 2006 it was reported that the site had been identified as a suitable location for a nuclear power station, based on the existing infrastructure and logistics.[9] Court caseOn 26 March 2015, the BBC reported that the UK government is being taken to court by the European Commission over excess emissions of nitrogen oxides from Aberthaw power station.[10] This issue was raised in the National Assembly for Wales on 10 November 2015 by Bethan Jenkins AM.[11] GallerySee also{{Portal|Wales|Energy}}
