Construction began in 1970 for the then South of Scotland Electricity Board. It was to be Scotland's first oil-fired power station. The soaring price of oil as a result of the 1973 oil crisis meant that by the time construction was completed generation was uneconomical. It was never utilised commercially, with 1200 MW kept in reserve and the remaining capacity being used to satisfy peak demand. It was only used at peak capacity during the miners' strike of 1984-85, when low coal supplies prompted operation. Generation ceased in January 1988 and although the plant was retained as a strategic reserve, it was never used as such. The plant was finally mothballed in the late 1990s, but was kept fully operational until 2006 when it was decommissioned. The power station's equipment was kept intact and continually operating dehumidifiers were used to keep it in good condition while the facility was unused. In construction, provision was made on site for a fourth generating unit, including a fourth stack inside the chimney, but the fourth generating unit was cancelled before construction commenced. One design feature of the power station is the lack of steam driven boiler feed pumps, with units 1 and 2 being provided with three 50% electric boiler feed pumps and unit 3 with two 50% electric feed pumps. The main turbo-generator was manufactured by Parsons, and many of the major components were interchangeable with the turbo-generators at Hunterston B around south, on the Firth of Clyde, also then owned by the South of ScotlandElectricity Board. Most workers lived in Wemyss Bay, many in housing provided by the Scottish Special Housing association, as well as the more affluent Lawrence estate. The turbines were also interchangeable with Torness and Heysham 2 power station; the stator from one of the turbines was transferred to Heysham 2 Nuclear power station in the 1990s under the CEGB which was then privatised to National Power, Powergen, Nuclear Electric and British Energy.
Demolition
The site has been cleared for housing and small business development. Preparatory demolition work started in April 2010. Since 2006, large amounts of equipment were removed to be used as spares at other power stations, including switchgear, turbine rotors, and control equipment. The last visits to remove equipment took place in March 2012. Electrical oil and other chemicals were drained to make the site safe, and major demolition began in June 2010 with the removal of one of the three large oil tanks. The northern section of the main building was demolished by a controlled explosion at the end of October 2012, and by November all three large oil tanks had been removed from the site. The main boiler room was demolished in February 2013. The final significant structure, its landmark chimney, was demolished by controlled explosions at 10 pm on Sunday 28 July 2013. Former Inverkip workers were relocated to Hartlepool or Heysham nuclear power stations.
