Name of the Project
Grand Ethiopian Renaissance Dam (GERD).

Location
The GERD is located 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 an estimated $4.8-billion.

Planned Start/End Date
In January, Ethiopia's Water and Energy Minister said that, following construction delays, the dam would start production by the end of 2020 and be fully operational by 2022.

Latest Developments
Sudanese Prime Minister Abdalla Hamdok has written to the African Union, the United Nations, the European Union and the US to formally request their mediation on the Nile water being used to fill the GERD.

He has expressed concern about Ethiopia's stated intention of adding more water to the reservoir behind the hydropower dam for a second year.
