Sup'ung Dam

Sup'ung Dam is a hydroelectric dam on the Yalu River, forming part of the border between North Korea and China. Its power station supplies electricity to both countries.

Hydroelectricity: Electricity generated by converting the energy of moving or falling water. Sup'ung converts stored river water into electricity through turbines.
Japanese rule in Korea: The period from 1910 to 1945 when Korea was annexed and governed by Japan. Construction began under Japanese colonial rule as industrial demand expanded.
Electric power: Energy transferred by electric currents to operate devices, infrastructure, and industrial processes. The dam's main product supports power systems on both sides of the river.
Yalu River boundary: The international boundary along the Yalu River between China and North Korea. The dam physically occupies a boundary river and embodies its divided jurisdiction.
Yalu River: A river in East Asia that flows along much of the border between China and North Korea. The dam spans this river and depends on its flow.
Manchukuo: A Japanese-controlled state in Northeast China that existed from 1932 to 1945. The dam's location and development served industry on both sides of the colonial-era border.
Power grid: An interconnected system for generating, transmitting, and distributing electricity. Sup'ung's output enters regional electricity networks rather than serving only the dam site.
Hydroelectricity in China: Electricity generated from water power within China. Sup'ung's output has historically been shared with Chinese areas across the river.
Hydroelectric dam: A barrier that stores or redirects water to generate electricity using turbines. This broader structure type explains Sup'ung's basic engineering role.
Korea under Japanese rule: Korea's political, economic, and social condition during Japanese colonial governance from 1910 to 1945. The project was built within the colonial system that mobilized Korean labor and resources.
