ERLANGEN, GERMANY- Siemens is again to deliver state-of-the-art power plant technology to South Korea. For the Ansan combined cycle power plant (CCPP), the company is supplying the Power Island consisting of two innovative SGT6-8000H gas turbines, one steam turbine, three generators, and two heat recovery steam generators as well as the entire instrumentation and control technology. Ansan is now the second power plant in South Korea to be equipped with the new gas turbines – SGT6-8000H – from Siemens.
The customer is the South Korean Posco Engineering & Construction Co. Ltd., headquartered in Incheon, which is responsible for construction of the entire plant. The CCPP Ansan will be fueled with liquefied natural gas (LNG) and will have a gross installed electrical capacity of 834 megawatts (MW) at a gross efficiency of 61 percent. In addition to generating electricity, the plant will also provide district heating for the inhabitants of the city of Ansan, which raises the overall fuel utilization factor to over 75 percent. Commissioning is planned for the end of 2014.
The Ansan CCPP is being built in the city of the same name in Gyeonggi-Do province southwest of the capital Seoul. Siemens is constructing the core element of the plant, the so-called power block, as a turnkey project and will supply the main components – two gas turbines of type SGT6-8000H, an SST6-5000 steam turbine, and three hydrogen-cooled generators of type SGen6-2000H. Siemens is also supplying two Benson heat recovery steam generators, and the SPPA-T3000 instrumentation and control system. A long-term service agreement has also been signed for the main components.
South Korea enjoys a burgeoning economy, with demand for electricity annually growing at the rapid rate of 3.6 percent. In the last ten years the installed power plant capacity rose from 60 gigawatts (GW) to more than 80 GW. However, the country has few energy resources of its own and is the second largest importer of LNG in the world. Because of high gas prices, high-efficiency CCPP play a particularly important role. "Ansan is now the second power plant in South Korea that we are equipping with our ground-breaking new gas turbine technology," said Roland Fischer, CEO of the Fossil Power Generation division at Siemens Energy. "We are pleased that we are making an important contribution towards a cost-efficient and environmentally friendly power supply."
"Because of our high gas prices, the efficiency of energy conversion is very important to us. Siemens offers to the date most efficient power plant technology and is an experienced and reliable partner in the handling of projects. We are pleased to be implementing this world-class project together with Siemens," said Kwang-Jae Yoo, CEO at Posco Engineering & Construction Division.
High-efficiency combined cycle power plants are part of the Siemens environmental portfolio, with which the company earned revenues of about €30 billion in fiscal 2011. This makes Siemens one of the largest global suppliers of environmentally friendly technology. Using Siemens products and solutions, customers saved nearly 320 million metric tons of carbon dioxide (CO2) during the same time period; this figure is equivalent to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo combined.
