Cockenzie power station was a coal-fired power station in East Lothian, Scotland. It was situated on the south shore of the Firth of Forth, near the town of Cockenzie and Port Seton, 8mi east of the Scottish capital of Edinburgh. The station dominated the local coastline with its distinctive twin chimneys from 1967 until the chimneys' demolition in September 2015. Initially operated by the nationalised South of Scotland Electricity Board, it was operated by Scottish Power following the privatisation of the industry in 1991. In 2005 a WWF report named Cockenzie as the UK's least carbon-efficient power station, in terms of carbon dioxide released per unit of energy generated. The 1,200 megawatt power station ceased generating energy on 15 March 2013 around 8.30am. the main station is being dismantled by Brown and Mason Ltd, a UK-based demolition company. There are plans to replace the station with a Combined Cycle Gas Turbine (CCGT) power station. The removal of the power station was done in stages with the iconic twin chimneys and the turbine hall of the power station being demolished in a controlled explosion on 26 September 2015, the front section of the boiler house being demolished on 4 November 2015 and finally the rest of the boiler house being demolished on 17 December 2015. This was the last remaining major structure to be removed.
