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.

Client
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 24 upstream bituminous 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 flood water discharged 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.

Value
The project is valued at an estimated $4.8-billion.

Duration
The project was initially expected to be completed in 2020, but is now expected to face a delay of several years.

Latest Developments
German mechanical engineering conglomerate Voith has signed an agreement to supply turbines for the GERD.

The agreement with Voith, which has already supplied 13 out of the dam's 16 turbines alongside France's Alstom, was made after the government, as a result of delays, cancelled a contract with its military-run Metals and Engineering Corporation (METEC) to provide the remaining three turbines in August this year.

METEC was the contractor for the electromechanical and hydraulic steel structure divisions of the project.

Italian firm Salini Impregilo remains the main contractor building the dam, while government plans to restructure METEC, which is set to be renamed as the National Metal Engineering Corporation.

Key Contracts and Suppliers
Salini Costruttori, a subsidiary of Salini Impregilo (construction contract) and Alstom (turbine and generators).

On Budget and on Time?
Government previously said the dam would be completed within two years, but is now expected to face a lengthy delay.
