Xiluodu Hydropower Project
Xiluodu Hydropower Project is
situated on the Jinsha River reach. It is a huge hydropower project with comprehensive
benefits of primary power generation, sediment controlling, flood controlling,
downstream navigation improving. The controlled basin area is 454.4×103 km2, which is 96% of the
whole Jinsha River basin area. The water level in normal storage is 600 m with
a total reservoir capacity of 12.67 billion m3, active storage
capacity of 6.46 billion m3
and
flood control capacity is 4.65 billion m3. The key structures
consist of dam, power conduit systems and power plants, flood discharge and
energy dissipation structures etc. The type of dam is concrete double-curvature
arch dam with a crest elevation of 610m and crest length of 700m. The maximum
dam height is 278 m. Seven 12.5m×13.5m
surface spillways, eight 6m×6.7m deep
outlets are arranged on the arch dam body. There are five spillway tunnels both
on the left and right banks separately. Two large underground power houses are
laid on the both banks separately, each has 9 turbine units with the single capacity
of 700MW, the total installed capacity of the project is 12600 MW, and the
annual average power generation is 57.12 TWh. The power conduit systems are composed
of intakes, headrace tunnels; main powerhouses, main transmission caverns,
tailrace surge chambers and ground surface switch stations.
The construction of Xiluodu
Hydropower Project began on Dec.26th, 2005. The total construction
period is 12 years and 2 months. It is planned to realize river closure in
2008. The project static investment is 45.928 billion RMB based on the 2001’s
price level.
