The Yeosu Thermal Power Plant consisted of two coal units commissioned in 1975 and 1977 (200 MW & 329 MW).[1] Around 2007, a fuel conversion project was launched to switch from heavy oil combustion to facilities based on fluidized bed boilers.[2]

Two coal-fired fluidized bed (CFB) units with 350 MW and 329 MW capacities replaced the aging units in 2011 and 2016. The renewed No. 1 unit was scheduled to start operation in November 2015, but construction ended in February 2016.[2][3][4][5]

Units 1 and 2 appear scheduled to close by 2046 and 2041 respectively.[6]

In April 2023, it was reported that KEPCO was collaborating with officials of Jeonnam Province, Yeosu City to "build energy self-sufficiency infrastructure" primarily via the installment of "solar power facilities and green hydrogen production facilities."[7] Reporting on the "low-carbon conversion projects" did not mention an attempt to expedite the retirement of the Yeosu power station coal-fired generation units.[7]

In October 2023, it was reported that plans for a future LNG conversion at the coal-fired power plant were being floated, though further details were not available at the time of reporting.[8]
