New Korea combined cycle power plant comes online

It’s the most efficient fossil-fired power plant in Asia.

South Korean power utility GS EPS Co. Ltd has taken over the Dangjin 3 (formerly Bugok 3) combined cycle power plant following the completion of its construction by Siemens Energy and GS E&C.

The Dangjin 3 power plant has a gross efficiency of almost 61% and an electrical capacity of 415 megawatts. It is located in Dangjin-City, Chungchong Nam-do Province some 120 kilometers south of Seoul.

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.

South Korea imports nearly its entire demand for gas in the form of liquid natural gas, transporting it by sea. It is also experiencing a rapid rise in demand for electrical energy, which is why it is planning to expand its generation capacity from 95 GW today to more than 150 GW by 2030.

Gas-fired power plants are expected to account for one-third of this total.
