Siemens and its partner POSCO Engineering & Construction (POSCO E&C), an affiliate of POSCO, have completed the construction of 834MW Ansan combined cycle power plant, in South Korea's Gyeonggi-Do province.

With an efficiency level of more than 60%, the power plant will provide district heating for the inhabitants of the city of Ansan.

The facility’s combined heat and power production raises its overall fuel utilization factor to over 75%, thus making it one of the most efficient and eco-friendly fossil-fuel-fired electricity generating plants in South Korea.

Owned and operated by S-Power, the Ansan plant is the first H-class 2 +1 multi-shaft power plant in Korea.

Siemens Energy Power Generation Division Business Unit Project Management Energy Solutions head Lothar Balling said: "Thus we are making an important contribution towards cost-efficient and environmentally friendly power supply in the Gyeonggi-do province at the right time to support the winter peak."

Siemens, as part of a contract signed earlier, delivered two Hclass gas turbines, one steam turbine, three generators and two heat recovery steam generators and entire instrumentation and control technology services for the plant.

The company is also responsible for the supply of the long-term service for the gas turbines.

POSCO E&C project manager Sung-Taek Seo said: "We selected the Siemens H-Class gas turbine technology and Siemens in-house basic engineering and project management capabilities in order to construct one of the most competitive power plants in Korea."
