# Korea Electric Power Corporation

Korea Electric Power Corporation, better known as KEPCO (Korean: 켑코) or Hanjeon (Korean: 한전), is the largest electric utility in South Korea, responsible for the generation, transmission and distribution of electricity and the development of electric power projects including those in nuclear power, wind power and coal. KEPCO, through its subsidiaries, is responsible for 96% of Korea's electricity generation as of 2023. The South Korean government (directly and indirectly) owns a 51.10% share of KEPCO. Together with its affiliates and subsidiaries, KEPCO has an installed capacity of 83,235 MW. On the 2023 Fortune Global 500 ranking of the world's largest companies, KEPCO was ranked 258. KEPCO is a member of the World Energy Council, the World Nuclear Association and the World Association of Nuclear Operators. As of September 2024, KEPCO possesses an AA credit rating with S&P Ratings, while Moody's has assigned KEPCO an Aa2 stable rating.
Originally located in Samseong-dong, Seoul, KEPCO headquarters was relocated to the city of Naju in South Jeolla Province in August 2014 as part of a government decentralization program. The move, which has been in the works for years has been controversial. Dong-Cheol Kim is the president and CEO of KEPCO.

## History

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.

Construction of KEPCO nuclear power plants is undertaken by major Korean construction companies, while the manufacture of key elements of a nuclear power plant is done by companies including Doosan Heavy Industries & Construction and Westinghouse Electric Company. In 2009, KEPCO won a bid to construct four units of the APR-1400 reactor in the United Arab Emirates at Barakah.
In October 2013, a vice-president of KEPCO, amongst about 100 people, was indicted for falsifying safety documents.
In 2017, KEPCO showed interest in taking a stake in the Moorside Nuclear Power Station in the UK, though did not proceed with the project.
In October 2020, KEPCO signed a memorandum of understanding with Daewoo Shipbuilding & Marine Engineering to develop a floating nuclear power plant based on the BANDI-60 60 MWe small modular reactor, which has been under development since 2016.

### Overseas activities

KEPCO's overseas forays started in 1993 when the company was awarded a technical consulting contract for maintenance on the Guangdong nuclear power plant in China. At present, KEPCO is involved in projects in 18 countries around the world. In 1996, KEPCO entered the Philippines power market when it was awarded the contract for the refurbishment and operation of the Malaya thermal power plant. In 1996, KEPCO won the bid to construct the Ilijan gas-fired combined cycle power plant, a 1,200MW build-operate-transfer project. Today, KEPCO operates four power plants in the Philippines, including the Naga Power Plant Complex and the Cebu Circulating Fluidized Bed Combustion Power Plant, while the company's operations account for 12% of the country's installed generation capacity. In April 2012 KEPCO contracted ICPO to raise $400m to buy into Boutique Coal in Australia to benefit from cheap coal briquettes which improved burn efficiency by up to 30% reduced SO $_x$ and NO $_x$ by >80% and reduced CO $_2$.
In the area of transmission and distribution consultation, KEPCO has undertaken projects in Myanmar, Cambodia, Vietnam, Indonesia, Libya, Ukraine, Paraguay and Egypt. KEPCO entered the wind power industry in China with its involvement in the Gansu wind project, on which the first stage of construction began in 2007. KEPCO also holds an equity share in wind projects in Inner Mongolia and Riaoning, as well as in China's Shanxi Province. In 2010, a KEPCO-led consortium including Samsung C&T and Korean firm Techint was awarded a contract to build and operate the Norte II combined cycle gas power plant in the Mexican state of Chihuahua. In 2005, KEPCO began supplying electricity to the Kaesong Industrial Region in North Korea.

### Resources development

In order to raise its fuel self-sufficiency rate to 60% by 2020, in 2010, KEPCO acquired the Bylong Coal Mine in Australia from Anglo American PLC. Also in 2010, KEPCO bought a 20% stake in Bayan Resources in Indonesia, thus allowing the company to raise its coal self-sufficiency rate by 7 million tons annually from 2015. In 2009, KEPCO bought a 1.5% stake in Indonesia's Adaro Energy, thus securing 3 million tons of coal annually. Regarding uranium procurement, in 2009, KEPCO acquired a 17% share of Denison Mines Corp. in Canada, as well as a 10% stake in Areva SA's Imouraren uranium mine in Niger. In 2010, KEPCO signed an agreement with Areva to jointly develop uranium mines.

### Smart grid

In early 2010, KEPCO announced it would invest over US$7 billion in its smart grid business by 2030 to make electricity distribution more efficient and decrease Korea's greenhouse gas emissions. KEPCO is one of the 168 Korean and foreign companies taking part in the Jeju Smart Grid Demonstration Project, begun following the announcement of Korea's National Smart Grid Roadmap in 2009. In June 2011, it was announced that KEPCO would collaborate with IBM to build a Total Operations Center at the Jeju Smart Grid Test-Bed Demonstration Complex.
