South Korea to build world's largest
tidal power station
May 04, 2007 - AsiaPulse
South Korea's Incheon City said Thursday
that it plans to build the world's largest tidal power
station on Ganghwa Island by 2014.
The project calls for connecting four
islands in Gyeonggi Bay with seawalls and installing
32 electric generators for a total output of 812 megawatts,
three times the capacity of the Rance tidal power
station in northern France, the current title holder
in the field.
The generators make electric power by
using the difference in water levels during high and
low tide, which can reach a maximum of 9.6 meters.
On average, the difference is about 6-7.6 meters.
The four islands are Ganghwa, Gyodong,
Seogeom and Seongmo.
Incheon, located 80 kilometers west
of Seoul, said construction will cost 1.77 trillion
won (US$1.90 billion). The port city has signed a
memorandum of understanding with Korea Midland Power
Co. and a consortium led by Daewoo Engineering and
Construction Co. (KSE:047040) to build the power facility.
Incheon said once commercial generation
starts in 2015, it can provide 8.4 percent of the
annual electric power used by the city, currently
18,165 gigawatt-hours. The electricity can power 400,000
of the 930,000 homes in the city, equivalent to burning
320,000 tons of heavy oil.
