South Killingholme

South Killingholme is a village and civil parish in North Lincolnshire, England. The population of the civil parish at the 2011 census was 1,108. The parish was predominately agricultural and sparsely populated and the village small until the 1960s when industrialisation of the south Humber bank took place throughout area north-west of Grimsby – within the parish of South Killingholme the Humber Oil Refinery was built in the late 1960s. At the same time the village greatly expanded reaching near its present (2006) scale by the early 1970s. The expansion of the Port of Immingham westwards encroached on the parish from the 1970s onwards, mainly due to the Immingham Bulk Terminal (1970) and later Immingham Gas Jetty (1985); in 2004 a 730 MW powerstation Conoco Philips Power Station (now known as Immingham Power Station) was built alongside the refinery. As of 2006 the land area of the parish consists of an approximately 50:50 split of heavy industry – petroleum storage, refining and power generation; and agricultural land. South Killingholme is the only village in the parish and is located roughly in the centre of area.
