{{#badges:CoalSwarm|Navbar-SouthKoreacoal}}Samcheok Green power station (삼척그린파워) is a 2,044-megawatt (MW) coal-fired power station operated by Korea Southern Power (KOSPO) of Korea Electric Power Corporation (KEPCO) for Samcheok, South Korea.

KEPCO said it plans to eventually expand the plant to 5,000 MW, powered by a mix of coal, biomass, and renewables.

Background on Plant

The plant was originally proposed in 2010 to consist of two 1,000 MW zero emission turbines equipped with carbon capture and storage (CCS). KEPCO has said they would like to expand the plant to 5,000 MW, powered by a mix of coal, biomass, and renewables.[1][2]

The plant will use "ultra-supercritical circulating fluidized bed" technology, allowing it to use lower grade coal (4,000 kcal/kg versus 6,000 kcal/kg in a typical pulverized coal plant) along with five percent wood chip biomass.[2] However, the efficiency of the process is rated at 38.8 percent, which matches that of the typical supercritical coal plant described in MIT's "Future of Coal" study.[3][4]

According to engineering firm Foster Wheeler, Kepco proposes that the plant be four units of 550 MW each, planned for completion by 2015.[5][6][3] However in May 2011 Toshiba Corporation received the contract to supply two 1,000 MW ultra-supercritical units to KEPCO.[7]

According to Korean sources, the first two coal units will be 1,022 MW each,[8] and completed in 2016. CCS is not mentioned.[9]

In May 2016 it was reported that unit 1 would be commissioned in December 2016 and unit 2 in January 2017.[10]

Unit 1 began commercial operation in December 2016.[11]

On May 6, 2017, Unit 2 was reported as 99.27% complete. It is planned for operation by June.[12] It was completed in June 2017.[13][14]
