About Us

Since May 1985. when it obtained a license for producing city gas, Daeryun E&S has contributed to the development and improvement in lifestyle for regional communities by providing LNG city gas to 800,000 households in Seoul (Seongbuk, Gangbuk, Dobong, and Nowon districts) and northern Gyeonggi-do (Euijeongbu, Dongducheon, Yangju, Pocheon, Yeoncheon).

The company, after obtaining a certification for Integrated Management Systems in Sep. 2003 (the first in Korea), was accordingly qualified as meeting international standards in the areas of city gas quality, the environment, and health & safety. This enabled the company to construct a safer, higher level advanced management system.

After its incorporation as a foreign invested company in July 1999 (during the period of the Asian financial crisis), it was included in the Hanjin Heavy Industries & Construction Group in May 2006 for a new stage of challenge as a leading provider of city gas in Korea.
