Provan Gas Works is an industrial gas holding plant in the city of Glasgow, Scotland. The plant lies between the Blackhill, Blochairn, Germiston and Provanmill areas of the city, and was built by Glasgow Corporation between 1900 and 1904. It later became part of British Gas, and subsequently Transco and most recently Scotia Gas Networks (a subsidiary of Scottish and Southern Energy) who operate it today. In 2020, the Scottish Prison Service announced that it intended to buy 22 hectares (54 acres) of land adjacent to the gas works to build a replacement for HM Prison Barlinnie.
