CCPP Exceeds 60% Efficiency

Siemens confirms South Korea as key market for LNG-powered electricity production, opening regional headquarters

Posted on February 5, 2014

In cooperation with consortium partner GS E&C, Siemens Energy has commissioned the Dangjin 3 combined-cycle power plant (CCPP) in Bugok, about 120 km south of the South Korea’s capital city, Seoul.

Dangjin 3 is a turnkey project by Siemens and GS E&C for independent power producer GS EPS, which invested US$460 million in the project. The plant features an SGT6-8000H fully air-cooled gas turbine in single-shaft configuration, an SST6-5000 steam turbine, and a hydrogen-cooled SGen6-2000H generator.

The 415 MW single-shaft, combined-cycle plant follows two other installations at the same Bugok site, all fueled by LNG: Dangjin 1, a 538 MW combined-cycle plant in 2+1 multi-shaft configuration; and Dangjin 2, another 2+1 multi-shaft combined-cycle facility using Siemens F-class technology and delivering 550 MW of power with an efficiency of 58.6% (LHV basis net).

Siemens said that Dangjin 3 has broken more than one record – it is not only the first 60 Hz combined-cycle plant  in Asia to achieve over 60% net efficiency, but this is also the first time the company has installed a single-shaft, combined-cycle configuration with an H-class 60 Hz unit.

Because South Korea has become a major market, Siemens said it is founding a new regional headquarters in Seoul for its Energy Solutions Business.
