Name of the Project
Grand Ethiopian Renaissance Dam (GERD).
Location
On the Abay river, in the Beneshangul Gumuz region of Ethiopia.
Project Owner/s
Ethiopian Electric Power Corporation (EEPCo).
Project Description
The project envisages a plant with an installed capacity of 6 000 MW that will supply 15 692 GWh/y.
The major components of the project include:
• a 145-m-high, roller-compacted concrete (RCC) dam with a 1 780-m-long crest;
• a rock-filled saddle dam, 4 800 m long and 45 m high, with a bituminous surface facing;
• two outdoor powerhouses of 3 750 MW and 2 250 MW installed capacity, containing ten and six generating units respectively, each with a capacity of 375 MW; and
• a 500 kV switchyard, which will transmit power from the two powerhouses to the grid.
The main dam and saddle dam will create 74-billion cubic metres of impounding capacity, with a surface area of 1 680 km2 at full capacity.
A gated spillway, equipped with six radial gates and a discharge capacity of 14 700 m3/s at probable maximum flood occurrence, will be located on the left side of the main dam.
A saddle dam on the left side of the RCC dam, with an emergency side spillway, is envisaged to allow for the discharge of floodwater directly into the Roseires reservoir.
The construction of 123 km of access roads, as well as camps, workshops and other civil works, form part of the activities for the project.
Potential Job Creation
Not stated.
Capital Expenditure
The project is valued at $4.8-billion.
Planned Start/End Date
The project started construction in 2021 and faced many delays. It is expected to be completed in 2023, barring any further delays.
Egypt is opposed to the project, alleging that the dam will endanger its water share, which violates the 1959 treaty. The treaty allocated 66% of the river’s water flow to Egypt, although Ethiopia was not a signatory to it.
Cairo insists that the project is being built without the permission of Egypt. Therefore, the dam is a threat to Egypt’s water safety. The African Union is still leading negotiations, aiming to reach a three-way agreement on the dam’s filling and operation.
Latest Developments
The project is more than 90% complete. The fourth filling of the dam’s reservoir is expected between July and August this year.
