The completion ceremony of ’s first USC (Ultra Super Critical) power stations, Danjin Thermal Power Plant Units 5 & 6 engineered by KOPEC, was held on June 9, 2006 at Dangjin Thermal Power Auditorium.

 The ceremony was held in the participation of some 300 people including the Minister of Commerce, Industry and Energy, CEO of KEPCO, CEOs of power companies, CEO of KOPEC, Governor of Chungcheong-do, Magistrate of Dangjin-gun, local officials and employees of related power and construction companies. Kim Cheol-su, director of KOPEC Plant Engineering & Construction Division, won the Industrial Award while project manager Kim Jeong-hoi received the Presidential Award.

 Starting with the Boryeong Thermal Power Plant Units 3 & 4, there are 22 500MW coal-fired thermal power plants currently in operation in Korea and based on the successful completion of the 1^st phase of the project to standardize 500MW coal-fired thermal power plants, the Dangjin Thermal Power Plant Units 5 & 6 were built and put in commercial operation in September 30, 2005 and March 31, 2006 as the first 500MW coal-fired thermal power stations in the second phase of the 500MW Coal-Fired Thermal Power Project three months ahead of the schedule since the groundbreaking for the main office began in July 2002

 Major Design Characteristics of the Dangjin Thermal Power Plant Units 5 & 6

 First, they are Korea’s first USC (Ultra Super Critical) power stations 2% or more efficient than other power stations with the main and reheat steam temperatures increased from 538°C/538°C to 566°C/593°C. Also, they can save about 150,000 tons of coal and reduce carbon dioxide emissions by about 800,000 tons a year.

 Second, equipped with high-efficient desulfurizer and DeNOx systems, they are environmentally friendly power stations designed for resource recycling using both heavy water and lake water.

 Third, the value engineering method was implemented to improve the performance, quality, lifecycle and maintainability while minimizing the LCC (Life Cycle Cost) throughout its lifecycle, and the power stations are also equipped with an ICMS (Integrated Control and Monitoring System) so that they can be monitored and ran from the main control room and improve operation reliability as well as reduce construction, operation, and maintenance costs.

 KOPEC expects that engineering, construction and testing experience gained in the project will create more synergistic effects in the construction of the Units 7 & 8 as well as other power companies’ upcoming projects to build their power plant units 7 & 8.
