Main Components
The Bedden Dam is a concrete gravity dam with a central
clay core rockfill embankment on both sides. The concrete
section
comprises:
A central concrete section, containing six low level
outlets for emergency drawdown;
A spillway section with thirteen gates for flood
discharge; A non overflow concrete section on the
island; Powerhouse (Size of powerhouse 252m x 46m x 62m (LxWxH)
and outlet works adjacent to the right bank. The power house
has a total capacity of 530MW and equipped with 6 Kaplan
Turbines, each with a capacity of 91.5 MW. The powerhouse
abstracts water directly from the reservoir through the six
power intakes. It is intended that a maximum discharge of
2,040m3/s will be diverted for energy generation. The dam
acts as a run-of-river diversion, with storage to retain
sufficient water for weekly loads. Minimum operating level
is only 1.0m below normal operating reservoir water
level. The Central Clay Core Rock fill Dam is approx 2,347 m
long on both sides of the Nile. The right and left bank
embankments will be founded on rock.
