Taean, South Korea -6.1W

Located in Chungcheongnam-do, South Korea, the 6.1-GW Taean power station stands second in the list of the world’s biggest coal power plants.

It also features a 300-MW integrated gasification combined cycle (IGCC) generator, which uses bituminous coal as fuel.

Between 1995 and 2007, eight 500-MW units were built for the power plant, which supplies electricity primarily to the South Korean capital and surrounding regions.

In 2012, Japanese conglomerate Hitachi and petrochemicals group Daelim Industrial secured a contract for the supply of two boilers of 1,050MW-class for units nine and 10 at the coal-fired thermal power plant.

The existing power station consists of eight 500 MW units built from 1995-2007. The 4,000 MW plant provides power to the South Korean capital and the surrounding regions and is located in Taeangun, Chungcheongnam-do, about 100km southwest of Seoul.

According to the country's 8th Basic Plan for Long-Term Electricity Supply and Demand (2017-2031), finalized in December 2017, Taean power station Units 1-2 will be converted to burn gas instead. The date of the proposed conversion is not listed.  However, in the 9th Basic Plan released in 2020, a schedule is set to replace coal units 1-6 with LNG plants from 2025-2032. 

Units 9 and 10 of 1,050 MW each (2,100 MW total) are scheduled for completion in 2016.

The new units were delayed due to accidents and defects. Before the completion of the project, the third stage of the turbine, which is the core cycle, was damaged and a fire occurred, delaying commissioning. Unit 9 was eventually completed in 2016, and Unit 10 is expected to be completed in 2017.

Unit 10 was completed in 2017.
