Background
The 424-megawatt (MW) Seagull cogen plant initially only had three-unit coal-fired power station units above 30 MW for a total of 146 MW (~55 MW, ~31 MW, and 60 MW[6]). The units were commissioned from 2007 to 2014. The Seagull steam power plant was operated by Gunjang Energy of eTEC E&C, to supply electricity and heat to the surrounding Gunjang industrial zone. It is now operated by SGC Energy.[7][8]
Unit 4
A 250 MW expansion was proposed. In 2014, a coal-burning circulating fluidised bed steam generator with a selective catalytic reduction system was ordered from the company Foster Wheeler. As of 2014, the plant was under construction and scheduled to come online in mid-2016.[7]
A contract was awarded to Hamon Korea in June 2014 and commercial operation began on May 18, 2016. The unit was reportedly 275 MW.[9]
Unlike units 1-3, unit 4's boiler receives Renewable Energy Supply Certificates (REC) by using a mixture of bituminous coal and allegedly eco-friendly wood pellets.[10][11]
Ownership & plans to reduce coal emissions
In 2020, Gunjang Energy merged with Samkwang Glass and E-Tech to form SGC Energy.[12] SGC Energy was described as a collective energy businesses that use biomass to supply process steam to 18 customers in the Gunsan Regional Industrial Complex and Chungnam through cogeneration using "clean woody biomass fuel."[13] SGC Energy has identified plans to reduce coal consumption and gradually expand biomass to respond to climate change.[14]
In November 2021, the company noted it had "completed the task of changing the fuel of a bituminous coal-based 60MW power plant to an eco-friendly one." It is unclear if this referred to units 1-3 or not. In addition the "250 MW cogeneration power plant," presumably Unit 4, was also "preparing to utilize domestic unused forest resources." The goal to have that done appeared to be around 2025 ("2025년쯤"), at which point the proportion of coal fuel in the company's "total sales" would be "less than 20%."[15]
In March 2022, a 60 MW unit, presumably Unit 3, was similarly reported as having been converted from a coal-fired unit to being fueled by "unused domestic forest resources" (Google Translate).[16] A 2022 report from parent company SGC Energy confirmed that Unit 3 was converted to a biomass-fueled unit in October, 2021.[17]
Owners fined for illegal internal trading
In July 2023, several sources reported that the plant owner, SGC Energy, had been fined along with two other SGC affiliates for internal trading.[18][19] According to reports, the "Fair Trade Commission found that these affiliates used tricks to enable Samkwang Glass [now SGC Solutions] to win the bid 13 times while conducting a total of 15 competitive bids for bituminous coal from May 2017 to August 2020."[18]
