1. The Grand Ethiopian Renaissance Dam

2. Location
l
Formerly called as project x
then known as the Millennium
Dam then it renamed to Grand
Ethiopian Renaissance Dam.
l
located on the Blue Nile River
in Ethiopia .
l
It is in the Benishangul-Gumuz
Region of Ethiopia, about 15
km east of the border with
Sudan.
l
Coordinates 11°12′55″N
35°05′35″E

3. Location

4. Design and Type
l
Gravity dam , 175 m tall, 1,800 m long and composed of
roller-compacted concrete. The structural volume of the dam
will be 10,000,000 m3 with a construction cost of $6.4 billion
USD .

5. Design and Type
l
Reservoir will have a
storage capacity of 74 billion
m3 and surface area of
1,561 km2 .
l
The dam will have three
spillways, the main one is
located to the left of the dam
and will be controlled by six
sector gates and have a
design discharge of 15,000
l
m3/s

6. Design and Type
l
Supporting the dam and reservoir will be a 5 km long and 50
m high rock-fill saddle dam. To the right of the saddle dam
will be a third spillway for emergencies.

7. Design and Type
l
The dam will be capable of handling a flood of 19,370 cubic
meters per second

8. Power station
l
At 6,000 MW, the dam will be the largest hydroelectric
power plant in Africa when completed, as well as the 7th
largest in the world. ( Hofer Dam 2000 MW)

9. Power station
l
The power stations are positioned on the right and left banks of
the river and estimated production of 15,000 GWh per year.
l
A major benefit of the dam will be hydropower production. The
electricity to be produced by the hydropower plant is to be sold in
Ethiopia and to neighboring countries .

10. Geology and Environment
l
The Nile river
l
Blue Nile
l
Head water : lake Tana ,

l
White Nile
l
lake vectoria , equitorial lake
, swamps

11. Geology and Environment
l
The Nile water that Egypt
relies on comes from two
sources. The first, and most
important, is the Ethiopian
Plateau, which supplies the
country with nearly 85 per
cent of its needs only during
the summer months, July to
October. Some 65 per cent
of these come from the Blue
Nile (BN), and the remaining
20 per cent comes from the
Atbara River.

12. Geology and Environment
l
The second source that
compensates the rest of the
year is the Great Lakes
region of Africa, which
provides about 15 per cent
of Egypt’s needs.
l
The dam lies over an area
which is dominated by per-
camberian metamorphic
rocks ( similar to red sea
mountains in formation ).*

13. Environmental Impact
l
Flow Stream Scenarios
the time periods needed to fill the reservoir of 74 BCM with water level 146 m, times
needed are 37, 14.8, 7.4 and 3.7 BCM/year respectively. These results refer to a
significant problem coming with charging the reservoir even at a long period time such
as 40 years. The effects of charging time sceneries of the reservoir on Egyptian water
demand were studied. The results showed that a sever water shortage problem will
affect Egypt even with using the storage water in Nasser Lake
The results referred to a significant problem coming with charging the reservoir even at
a long period time such as 40 years.

Mohamed Helmy Elsanabary

14. Environmental Impact
l
Damage Scenario
l
In case of dam breach, a severe flood will result in
inundation of the Senner dam with 15 km width and 200 km
long and the areas in between until it reaches Khartoum.
Also, excessive water level rise with 3 m is expected from
the dam until it reaches Nasser Lake.

15. Environmental Impact
With the huge reservoir scenario of 79 BCM, 122,000 people
will be displaced and 7 million tons of CO2 emissions.
The agricultural lands and scattering millions of families will
be affected due to the reduction in the water share of
downstream countries especially in Egypt.

16. Recommendation
l
Nile river countries should work together in order to find a
compromise solutions and to prevent many hazards which
may lead to sever damages .
