New CCPP Erected in Record Time

The 417-MW Andong combined cycle power plant (CCPP) constructed in the province of Gyeongsangbuk-do, in South Korea, was completed in only 24 months.

Owned and operated by Korea Southern Power Co. Ltd. (KOSPO), the plant is fired using liquefied natural gas and utilizes a Siemens SGT6-8000H gas turbine, an SST6-5000 steam turbine, an SGen6-2000H generator, and a Benson heat recovery steam generator. The CCPP operates at an efficiency level of more than 60% and is designed for 250 starts per year. With a startup time of 30 minutes from standstill to full load, the plant offers KOSPO the flexibility to react quickly to demand changes in the Korean power market.

“We place special emphasis on maximized efficiency, operational flexibility, and environmental friendliness,” declared Lee SangHo, president and CEO of KOSPO.

“The trustful relationship developed with KOSPO and our partner GS E&C made it possible to execute this high efficient H-class single shaft power plant in a record time with highest quality to support the high power demand in the Andong area. The project execution also was a benchmark in terms of health and safety and zero harm in Korea,” said Lothar Balling, executive vice president and head of global project management in the Siemens Energy Power Generation Division.

Three other CCPPs with H-class gas turbines are also under construction in South Korea with a total capacity of 2.5 GW. Those facilities are scheduled to come online over the course of the next two years.
