The story
KOGAS was established in August 1983 under the Korea Gas Corporation Act (Law 3639, enacted December 1982), to supply natural gas for public convenience and welfare.
The company introduced liquefied natural gas to South Korea in 1986, beginning supply to the Pyeongtaek Thermal Power Plant that November. Supply was extended to the Seoul metropolitan area in 1987, central Korea in 1993, the southern mainland in 1995, the west coast in 1999 and Gangwon-do in 2002. KOGAS began supplying previously unconnected mainland areas in 2009 and Jeju Island in 2019, by which point the national pipeline network formed a single loop.
KOGAS was listed on the Korea Exchange in December 1999 and designated a market-type public corporation in 2007.
