KOMIPO Dedicates 4
Pumped-Storage Units

Capable of producing electricity of 1 million kW


The Yangyang Pumped-Storage Power Plant Units 1 through 4 with a total capacity of 1 million kW, Korea's largest one, has been put into operation during a dedication ceremony after 10 years of construction.
On hand at the dedication ceremony held at the plant complex in Seo-myeon, Yangyang-gun, Gangwon Province, on September 12 were Lee Won-gul, vice minister for energy at the Ministry of Commerce, Industry and Energy, KEPCO Chairman-CEO Han Joon-ho and Korea Midland Power Co. President Chung Jang-sup and other dignitaries and neighborhood residents.
The completion of the Yangyang Pumped-Storage Power Complex, with a capacity, equivalent to a nuclear power unit, brings from 6.5 percent to 7.5 percent the portion of hydroelectric power production of Korea's total power production capacity. The complex accounts for 65 percent of power generation coming from the nation's pumped-storage power units.
Saman Corp. designed the power units, Doosan Heavy Industries & Construction supplied the equipment,
and Sanhwan E&C and Samsung E&C were in charge of construction.
The project was completed about 10 years after it broke ground in September 1996. It cost 1.1 trillion won and about 1.7 million man-days.
The Yangyang Pumped-Storage Power Complex has an 819 meter head of water between the upper and lower dams, the largest one in Asia. A fish way has been created at the lower dam to preserve the ecosystem.
The dedication of the power complex is designed not only to produce environmentally-friendly energy, but also to stabilize the power systems and cope with the obligations of the conventions on climate change.
KOMIPO has provided 26.3 billion won to finance such projects as a village hall and waste treatment facility construction as part of its efforts to stimulate the economy of the neighborhood area. To this end, the power generation company also plans to channel 1.1 billion won.
In a related development, 48 KOMIPO staff members and officials from related companies were presented with government orders, medals and presidential citations in recognition for their contribution to the completion of the power complex. nw
