Doosan Enerbility Achieves Localization of Gas Combined Cycle Power Generation... First Order of 380MW-Class Gas Turbine

Ultra-large Gas Turbine Developed with Purely Domestic Technology
Supply Contract for Main Equipment with Jungbu Power and Boryeong New Combined Power Plant

Doosan Enerbility has succeeded in securing an order for a 380MW-class ultra-large gas turbine developed purely with domestic technology. This marks the start of the first domestic project setting the standard for Korean-style combined cycle power generation.

Doosan Enerbility announced on the 28th that it has signed a main equipment supply contract worth 280 billion KRW with Korea Midland Power for Unit 1 of the Boryeong New Combined Cycle Power Plant. Doosan Enerbility succeeded in domestic production of large gas turbines for power generation in 2019 and has been promoting the development of combined cycle models as a national project with over 340 domestic industry-academia-research institutions since 2021.

The Boryeong New Combined Cycle Power Plant is being constructed in Boryeong City, Chungnam Province, with a target completion date of June 2026. It has a power generation capacity of 569MW. Doosan Enerbility will supply a 380MW H-class ultra-large gas turbine, steam turbine, and heat recovery steam generator to this power plant. Gas turbines are classified by capacity into small (20?99.9MW), medium (100?214.9MW), large (215?299.9MW), and ultra-large (300MW or more). The H-class turbine is a high-efficiency turbine made of superalloy materials that withstand temperatures above 1500°C. Korea Midland Power plans to convert the Boryeong New Power Plant into a hydrogen combined cycle power plant to achieve '2050 Carbon Neutrality.' Conversion to a hydrogen turbine is possible by replacing only the gas turbine combustor nozzles and some auxiliary equipment.

Doosan Enerbility has been developing 50% hydrogen co-firing technology for high-efficiency H-class hydrogen turbines as a national project under the Ministry of Trade, Industry and Energy since 2020, in collaboration with domestic industry-academia-research institutions. Technology demonstration is being conducted at the East-West Power Ulsan Combined Cycle Power Plant. The world's first 400MW ultra-large hydrogen full combustion turbine is also being developed with a target year of 2027. Installing H-class hydrogen turbines in power plants is expected to reduce annual fuel costs by approximately 60 billion KRW and carbon emissions by about 50,000 tons compared to existing E-class hydrogen turbines. Jeong Yeon-in, CEO of Doosan Enerbility, said, "We will lay the foundation not only for revitalizing the domestic gas turbine industry ecosystem but also for advancing into overseas markets."
