Boryeong power station

From Global Energy Monitor

Boryeong (Poryong) power station (보령 발전소) is a 4,350 megawatt (MW) power station (3,000 MW coal-fired and 1,350MW gas-fired) in Boryeong, Chungcheongnam-do, South Korea.

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

Background on Plant

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.[1]

Units 1-2, which are subcritical, were planned for retirement in 2025.[2] In May 2017 President Moon Jae-in said the two units will be shut down by 2022,[3] later moved to 2021,[4] and then December 2020. They were retired in December 2020 as planned.[5]

As of 2020, the two units were expected to be replaced by an LNG plant.[6]

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.[7]

The gas proposal, expected to come online in 2025, was for two LNG-fueled units of 500MW each.[7]

The Plan (“발전설비 건설계획표” section) also noted a 50 MW expansion at Unit 3 in 2020.[7] The KOMIPO website confirms that the coal plant includes one 550 MW unit.[8]

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.[9]

As of 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.[10]

Opposition

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.[11][12]
