Background of Hydropower DevelopmentBackground of Hydropower Development

Hydropower potential survey1) First Survey (1910-1913)

To correct understand potential

2) Second and Third Survey (1918-1923, 1937-1941)

To make efficient use of hydropower resource

3) Fourth Survey (1956-1959)

To cope with peak load

4) Fifth Survey (1980-1985)

To strengthen the hydropower development

5) Review of Fifth Survey (1993-1995)

To review the promising sites
