한국전력공사
KEPCO traces its origins to "Hanseong Jeongi Hoesa" (Seoul Electric Company), founded in 1898 during the Joseon Dynasty. The announcement of the Chōsen Electricity Control Decree by the Colonial Korean government in March 1943 saw the integration of several electric companies into the Korea Electric Power Company. The Korea Electric Company (KECO), established through the integration of the Korea Electric Power Company and two distribution companies, Gyeongsung Electric Company and South Korea Electric Company, opened on 1 July 1961. In 1982, KECO became a wholly government owned entity and was renamed the Korea Electric Power Corporation (KEPCO).
