Siemens has said that, after a construction period of 26 months the plant was put on line about one month ahead of schedule in March 2008. Siemens has also signed a 20-year maintenance agreement with GS Electric Power and Services (GS-EPS) for the Bugok-1 and Bugok-2 plants.

In addition to the turnkey construction of Bugok-2, Siemens has also supplied key components including two SGT6-4000F gas turbines, the steam turbine with condenser, three generators, water-steam cycle components, process engineering, instrumentation and controls, and the distributed control system SPPA-T3000.

Siemens had previously constructed the Bugok-1 plant which has an installed capacity of 550MW. The two Bugok units, approximately 100km south of Seoul, are reportedly the first projects awarded to a foreign company by an independent South Korean power producer.
