Siemens Finishes Construction of Most Efficient Fossil-Fired Plant in Asia


Siemens Energy and its partner, GS Engineering & Construction (GS E&C), handed over the most efficient fossil-fired power plant in Asia to the South Korean power utility GS EPS Co. Ltd. The handover of Dangjin 3 (formerly Bugok 3) combined cycle power plant took place twelve days ahead of schedule. Thanks to the main components, Siemens’ world record-breaking H-class gas turbine and the special steam cycle, the power plant has a gross efficiency of almost 61 percent and an electrical capacity of 415 megawatts (MW).

The Dangjin 3 power plant is located in Dangjin-City, Chungchong Nam-do Province, approximately 120 kilometers south of Seoul. As the head of a consortium, Siemens built the plant as a turnkey project together with GS E&C and supplied a SGT6-8000H gas turbine, a SST6-5000 steam turbine, an SGen6-2000H hydrogen-cooled generator, a Benson heat recovery steam generator as well as parts of the electrical equipment and the SPPA-T3000 instrumentation and controls system. The company was also responsible for commissioning the power plant.

“At the moment, Korea’s biggest challenge is to even out the imbalance between power consumption and demand,” emphasized W.K. Lee, CEO of GS EPS. “Our Dangjin 3 power plant uses Siemens technology for maximum flexibility.”

South Korea imports nearly its entire demand for gas in the form of liquid natural gas, transporting it by sea. The efficiency of gas-fired power plants thus plays a crucial role for the country. South Korea is also experiencing a rapid rise in demand for electrical energy, which is why it is planning to expand its generation capacity from 95 gigawatts (GW) today to more than 150 GW by 2030. Gas-fired power plants are expected to account for approximately one-third of this amount. Siemens and its partners are currently building the Ansan, Andong, Posco and Daegu combined cycle power plants in South Korea. The company will equip all four plants with H-class gas turbines as well as other main components consisting of generators, steam turbines and heat recovery steam generators.

Highly efficient combined cycle power plants are part of Siemens’ Environmental Portfolio. In fiscal 2012, revenue from the Portfolio totaled about €33 billion, making Siemens one of the world’s largest suppliers of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by more than 330 million tons, an amount equal to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo.
