in 1887 circa 1898 KEPCO traces its origins to
Hanseong Jeongi Hoesa (Seoul Electric Company), founded in 1898 during the Korean Empire. It was wholly invested by
King Gojong, who had a special interest in implementing electrical business in Korea; internally, the imperial-invested company was funded through Hanseong Electric's president Lee Chae-yeon. Subsequently, American businessmen Henry Collbran and Harry Rice Bostwick were contracted to manage Seoul's streetcars, lights, and telephone systems. Hanseong Electric completed its first
power plant in 1899 at Dongdaemun. By the end of that year, the company had succeeded in launching its
streetcar service, and soon after had turned on its first electric lights in Seoul's Jongno Street. With a monopoly on Seoul's electricity and streetcar systems, Hanseong Electric continued to build up its public lighting network into the turn of the century, and began offering electrical service to private homes as well. The company had also established a movie theater of which could be travelled to via the main line, a
streetcar line that went through downtown Seoul and multiple districts; experts recall that opening an electric movie theater was part of a marketing ploy to promote the convenience of trains and attract tram passengers. A total of three lines were constructed, all of which connecting 5 different districts of Seoul (Seodaemun-Jongno-Dongdaemun-Cheongnyangni (Main Line), Jongno-Namdaemun-Yongsan (Yongsan Line), and Seodaemun-Namdaemun (Uiju Line)). Up until the
Eulsa Treaty, the company had proved successful in expansion. Supporting the expansion included the enthusiastic support of Allen, a U.S. Legation official, including Lee Chae-yeon (the president), William F. Sands, a former secretary appointed as an internal adviser to the palace, and the active support of pro-American officials in Korea, including Lee Yoon-yong, Min Young-hwan, Min Sang-ho, and Kang Seok-ho. The company's president Lee Chae-yeon, who was a pro-American leader, died in August 1900. Upon this, non pro-American Lee Yong-ik joined the executives of
Hanseong Electric Company, tightly controlling the company's funding and strictly blocking Collbran's business expansion plans. Claiming it broke the mortgage contract, Collbran responded in demand for the repayment of debts related to the
railroad construction project and pressed on profits. Lee Yong-ik refuted Collbran's request based on the "Brown Paper," which stated that Collbran's claims were over-inflated; this caused tensions to rise. Soon, a new contract was signed to settle the debt dispute of Hanseong Electric Company. Gojong mutually withdrew all demands between the two sides, and in February 1904 established Hanmi Electric Company (韓美電氣會社) to hand over all rights and assets. The management of Hanmi Electric Company was held by Collbran, and 50% of the company's shares were acquired by Gojong which increased his involvement and management of the company as the majority shareholder. However, after Japan had won the
Russo-Japanese War in September 1905, Japan had expanded their influence in the Korean Empire with the signing of the
Eulsa Treaty. This included the process of absorbing, dismantling, and taking over various reform projects that the
Korean Empire had pursued independently. The electric power industry, the basic industry of modern commercial and industrial development, was no exception. In June 1909, Collbran sold
Hanseong Electric to a Japanese business named Ilhanwasa Co., Ltd 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). KEPCO was listed on the
Korea Stock Exchange on 10 August 1989 and later in 1994 on the
New York Stock Exchange. In 1996, KEPCO was named the prime contractor for the multinational
Korean Peninsula Energy Development Organization (KEDO) project to construct a light water reactor nuclear power plant in North Korea, a project which was eventually abandoned in 2006. Following a push by the Korean government to restructure Korea's power industry which began in the mid-1990s, the
Act on the Promotion of Restructuring the Electric Power Industry was proclaimed on 23 December 2000, after which the electricity generation business was split up into
Korea Hydro & Nuclear Power, a subsidiary responsible for nuclear & hydro power generation, and five thermal power generation companies: Korea South-East Power, Korea Midland Power, Korea Western Power, Korea Southern Power, and Korea East-West Power. In October 2012,
Korea Deposit Insurance Corporation sold its 3.6% of its stake in KEPCO for a fee of around $550 million. == Timeline ==
