Korea dedicates 1,000-MW Yangyang pumped-storage

Korean officials dedicated the 1,000-MW Yangyang pumped-storage plant September 12 at Yangyang in Gangwon Province.

The ceremony, led by plant owner Korea Midland Power Co. (Komipo), marked completion of the 1.1 trillion won (US$1.14 billion) project, whose construction began in 1996, 215 kilometers northeast of Seoul.

Yangyang features four 250-MW pump-turbine motor-generators in an underground powerhouse at Sangbu Dam. The upper reservoir is 937 meters above sea level and boasts Asia's highest maximum operating head of 817 meters, Komipo said.

Komipo, a unit of Korea Electric Power Corp., said the project is also notable for its environmental protection measures, including fish passage facilities.
