Background

The power station is separate from the Shin Boryeong power station (신보령화력).

The Boryeong power station consists of 8 coal-fired units of 500 MW each, built from 1979 to 2009, for a combined capacity of 4,000 MW. The scrubbers on Units 3-6 were retrofitted in the late 1990s. It is owned by KOMIPO.[17] The power station was located just two kilometers from the community center.[18]

Units 1-2, which are subcritical, were planned for retirement in 2025.[19] In May 2017 President Moon Jae-in said the two units will be shut down by 2022,[20] later moved to 2021,[21] and then December 2020. They were retired in December 2020 as planned.[22]

As of 2020, the two units were expected to be replaced by an LNG plant.[23] However, the Government’s 9th Basic Plan for Electricity Supply and Demand 2020-2034 (“연차별 석탄 폐지 및 LNG 전환 계획” section) highlighted an LNG Conversion for Units 5 and 6 by 2025 instead.[24] The gas proposal, expected to come online in 2025, was for two LNG-fueled units of 500MW each.[24]

The Plan (“발전설비 건설계획표” section) also noted a 50 MW expansion at Unit 3 in 2020.[24] The KOMIPO website confirms that the coal plant includes one 550 MW unit.[25]

In August 2021, the Electricity Commission approved conversion from coal to gas at Unit 5, which is seen as the first step in licensing and permitting to convert coal power generation to LNG power generation.[26]

In 2021, there were three 450 MW combined-cycle units operating on LNG fuel at the site. Originally, four units were installed. However, Unit 4 was relocated to KOMIPO's Incheon power station in 2009.[27]

In April 2023, the "10th Basic Plan for Electricity Supply and Demand" extended the planned dates of retirement for Units 5 and 6 a year further, from 2025 to 2026.[28]

Scheduled retirements and conversions

Units 3 and 4 were scheduled to close by 2043; Units 5 and 6 were scheduled to close by 2025; Units 7 & 8 were scheduled to close by 2038.[29][24]

Unit 5 is scheduled to be replaced by an LNG combined cycle power plant in 2026, as well as Unit 6 which is planned to be replaced at an unspecified date.[30] By September 2023, the construction contract for the combined cycle replacement unit (of Unit 5) had been awarded.[31]

Hydrogen co-firing plans

October 2023 reports stated that Korea Midland Power Company had been conducting trials of co-firing hydrogen within gas-fired power generation units.[32] Ko Energy stated that the company expected to be co-firing hydrogen at a rate of 30% by the second half of 2027.

Working conditions

As of 2022, several articles have highlighted work life at the plant. In April, a plant employee stated that unit closures and transitions to LNG were causing thousands of workers to lose their jobs.[33] In May, workers protested that the new Serious Accident Punishment Act was leading to over-surveillance of the day-to-day rather than actually making the power station safer.[34] In June, a fire occurred at the plant in the middle of the night.[35]

In February 2023, it was reported that a coal plant worker had fallen to his death at an unloading facility at the plant, allegedly due to a damaged scaffolding. [36] This happened four years after another on-the-job death of a contracted worker in 2018.[36]

Community opposition and impact

In 2021, residents near the plant led protests related to the plant – including its northern ash disposal site – and flagged high cancer rates in surrounding communities.[37][38]

In November 2022, a news article highlighted that the power station had negatively affected the surrounding community's livelihood and health. Residents recounted that the size of shellfish has decreased, and incidences of chronic illness had increased. One community member stated (Google translate): “If you sweep the ground with your hands like this when it is not raining, it will be black... There are no gentlemen who are not sick... and when they say they're dead, it's cancer." Rates of respiratory illness-related death in Chungcheongnam-do were 1.5 times higher than the national average of South Korea.[18]

In January 2023, a five year study in Chungcheongnam-do revealed that the concentration of mercury and cadmium in urine increased the closer residents lived to Boryeong power station. Rates were also elevated for cancer, skin disease and anxiety.[39]

A health impact survey in 2022 revealed increased rates of gastric cancer and liver cancer for residents in proximity to the power station. [40]
