In a record time of just 24 months, a combined cycle plant has emerged in South Korea which has also become the power plant with the least emissions in the country. Germany’s Siemens and its South Korean partner Posco Engineering & Construction have been responsible for building this 834 MW plant that will operate with a 75% of fuel.
Siemens, a global leader in technology, together with its South Korean partner POSCO Engineering & Construction, a subsidiary of POSCO, one of the world’s largest steel companies, has built a combined cycle power plant in Ansan in record time, just 24 months.
Efficiency level above 60%
It is the fourth combined cycle power plant in Asia based on class H by Siemens, with an efficiency exceeding 60%. In addition to generating electricity, the plant will provide district heating for the inhabitants of the city of Ansan. The combined production of heat and power raises the fuel utilization factor over 75%. Also, its NOx emissions of 7 ppm, are the lowest in the country, which makes it the most efficient and ecological power plant in South Korea.
The Ansan cogeneration plant, owned and operated by S-Power, is located in the city of the same name, in Gyeonggi Province, southwest of the capital, Seoul.
This plant, which uses liquefied natural gas (LNG), is Korea’s first power plant of the H Class in a 2 + 1 multi-axis configuration and has an electrical capacity of 834 megawatts (MW). Siemens will supply the main equipment of the power island: two SGT6-8000H gas turbines, one SST6-5000 steam turbine, three hydrogen cooled generators of the SGen6-2000H model, and two heat recovery boilers of BHI from South Korea as well as all the SPPA-T3000 instrumentation and control technology. In addition, the technological firm will provide long-term maintenance for the gas turbines.
With this plant, Siemens contributes to a low cost and environmentally friendly energy supply, which significantly increases the competitiveness of Korea’s electricity in line with one of the government’s goals.
It is worth noting that Siemens has sold fifteen SGT6-8000 H gas turbines to South Korea for eight combined cycle plants projects accounting to a total installed capacity of 6.3 GW. So far, four Class H projects have been completed, while four others are under construction. Commercial operation is scheduled for 2015 and 2017.
In October 2013, Siemens incorporated a new company, Siemens Energy Solutions Ltd. in Seoul / South Korea that will act as its new regional headquarters to serve power plant solutions to the Asian and Middle Eastern markets.
The German company has global excellence centers in Spain where it innovates, manufactures and exports such as Cornellà (railway material), Getafe (portable radiology equipment) or Rubi (electrical equipment).
