twin chain grate stokers could deliver 253 kg/s of steam at 42.7 bar and 468 °C. Cooling water to condense steam in the plant was drawn from the river estuary. The generating capacity and output was: In the year ending 31 March 1981 the station delivered just 0.2 per cent of its capability. In March 1984, it was announced by the Central Electricity Generating Board that the power station would close by the end of October that year. Fuel for the power station was obtained from coal mines in South Wales, and was transported across the Bristol Channel onto a jetty specially constructed for the power station. However, due to the closure of the coal mines in the 1980s, coal would be more expensive to obtain from other areas of the country. Therefore, it was more economical to close the power station. Today, most of the power station, which covered an area of 3.1ha, has been demolished.
