Dangjin power station

From Global Energy Monitor

Dangjin power station (당진화력) is a 6,040 megawatt (MW) coal-fired power station owned by Korea East-West Power Company in Dangjin, South Korea.

The plant is #3 on the list of Top ten largest coal plants in the world.

The Dangjin coal-fired power complex comprises eight units of 500 MW each and two units of 1,020 MW each, with a total capacity of 6,040 MW.[1] The eight units were commissioned from 1999 to 2007.[2]

Description of expansion

Two new units, units 9 and 10, were added in July and September of 2016. Although designed at 1,020 MW, the units were operating at 930 and 993 respectively due to turbine problems.[3]


Financing for units 9 and 10 was provided through bonds from the following entities: National Pension Service (US$374,844,730), NongHyup Life Insurance (US$82,284,131), Nonghyup Bank (US$45,713,406), Nonghyup Property and Casualty Insurance (US$27,428,044), NH Investment Securities (US$732,336,986), Korea Post (US$69,479,939), IBK Affiliates (US$27,426,596), and Industrial Bank of Korea (US$99,649,964).[4]

Environmental & public health concerns

The community faces significant pollution from the power station. For example, on a windy day, coal dust issues plague community residents who can't hang their laundry outside or keep windows and doors open. Shin Wan-soon, secretary-general of the Dangjin City Development Committee and a resident of Gyorori, said, “If you plant cabbage in the fall, the leaves will get burnt to the extent that they cannot be eaten.” From 1991 to 2019, South Chungcheong Province produced 2.26 million GWh, or 22% of the country's total electricity, of which nearly 60% was transmitted to other regions. 484 transmission towers were built in Dangjin alone to send electricity to various places. Special support project funds allocated to the area around the power plant are reportedly used erratically and fail to support residents.[5]

One of the largest coal plants in the world

In July and December 2016, the expansion raised the capacity of the plant from 4,000 MW to 6,040 MW, although turbine problems with Units 9 (operating at 930 MW due to turbine problems) and Unit 10 (operating at 993 MW due to turbine problems) reduced the plant's overall capacity to 5,923 MW (according to press reports)[3] or 5,860.2 MW (according to Korea East-West Power Company.)[6] The plant is the third largest in the world, behind Datang Tuoketuo power station in China and Taean power station in South Korea. (See Top ten largest coal plants in the world.)

Conversions to gas (Units 1-4)

South Korea plans to shut a total of 15.3GW of coal-fired capacity by 2034, according to a draft of the country's ninth basic electricity plan, of which 12.7GW will be switched to run on imported gas.[7]

The following power stations have plans to convert from coal to gas:[7]

In June 2022, Korea East-West Power announced that they would be conducting environmental improvements to Units 1-4 to combat the aging infrastructure of these older units. They claimed that this work will reduce pollutant emissions by 25% by mid 2023.[8]

Additional Site Details

Planned Unit Retirements: Units 1 & 2 are scheduled to close by 2029; Units 3 & 4 by 2030; Unit 5 by 2035; Unit 6 by 2036; Units 7 & 8 by 2037; Unit 9 by 2045; Unit 10 by 2046.[9]

In March 2022, the Director of the Nuclear Policy Center at Seoul National University suggested that a nuclear power plant could be built on the site of the Dangjin power station following the retirement of the coal-fired units. The Dangjin Environmental Movement Federation condemned the idea and called it reckless.[10]
