GS Energy has established a trading division responsible for direct procurement of LNG to supply our downstream demand centers. This expansion into the mid-downstream sector opens opportunities to move further upstream in the LNG value chain going forward.

GS Energy supplies LNG to our downstream demand centers via our newly constructed LNG regasification terminal in Boryeong. GS Energy looks to further expand its trading volume and continue to provide a stable source of fuel to our LNG power plants.

Further, through our subsidiaries Haeyang City Gas and Seorabeol City Gas, GS Energy provides gas distribution services to residential and commercial customers in Cheollanam-do Kyungsanbuk-do. GS Energy has been able to successfully develop an integrated LNG value chain domestically, and now looks to expand this business model in overseas markets.
